TECHNICAL FIELD

[0003] The present application relates to the field of wireless communications, and more specifically to methods, apparatuses, and systems for facilitating navigation of, for example, a vehicle. BACKGROUND

[0004] Autonomous driving systems, such as autonomous vehicles, rely on sensors to obtain relevant and timely data needed to facilitate effective navigation. The sensors generate data indicative of driving conditions and forward the generated data to the autonomous driving system for navigation purposes. However, the sensors can not generate data, or even reliable data, in all situations, particularly when driving conditions change. The availability and accessibility of reliable data is particularly important for effective responses to changes in driving conditions. The lack of relevant and timely data can render the autonomous driving system less useful. Accordingly, the effectiveness of the autonomous driving system becomes significantly dependent on the system’s response to changing driving conditions.

[0005] Thus, there is a need for methods, apparatuses, and systems for facilitating navigation of a mobile device, such as a vehicle, that can eliminate or alleviate one or more of the limitations in the prior art.

[0060] Embodiments of the application provide methods and apparatus for facilitating navigation of mobile devices, such as autonomous vehicles on a road or network of roads. Routes along the road are defined, for example, in the form of lanes having a given width, and followed by a plurality of consecutive mobile devices. These routes are overlaid on map information indicating the location of the road, and can be defined as a series of geo-tags following a portion of such a road. The combination of the routes overlaid on the map information results in a dynamic map that is updated in response to changes in conditions. The map information can be relatively static, only the overlaid portion changing over time. The routes are defined by an automated controller running in or coupled to network infrastructure, and transmitted wirelessly to the mobile devices, which are then configured to follow the routes.

[0061] The route is further dynamically defined and adjusted based on current operating conditions. These operating conditions can include traffic conditions, such as traffic congestion conditions, or to accommodate the requirements of one or more higher priority mobile devices, such as emergency mobile devices. Operating conditions can include the appearance of obstacles on the road, such as a vehicle breakdown or vehicle collision, or large potholes, debris, etc.

[0062] While the routes described herein are defined, it should be understood that it can be the characteristics of the route that are determined, defined, or selected, rather than the route itself. The characteristics of the route can correspond to one or more lanes of traversal through a physical road, and the route can include at least one of the lanes described above. The characteristics can correspond to a line that indicates the route, where the route includes a set of geographic points positioned along the line. In embodiments and throughout this disclosure, the characteristics can be virtual lanes.

[0063] Embodiments of the present application can define which path on a particular physical road should be followed by dynamically defining virtual lanes that do not necessarily rely on pre-established painted lanes on the road, and directing mobile devices to follow such virtual lanes. Multiple virtual lanes can be defined, where one or more mobile devices are directed to follow each of the multiple virtual lanes.

[0064] Operating conditions can be transmitted to the automated controller from a variety of sources. Sources can include (e.g., fixed) traffic monitoring devices (e.g., cameras or other sensors) deployed along or within the physical road. Such sources can indicate conditions such as traffic load and mobile device speed on the road, and the appearance of debris, breakdowns, or collisions. Other sources can include the mobile devices themselves, which can transmit data from their own sensors or cameras or telemetry data such as desired speed or route, desired level of service, current speed, breakdown alerts, etc. Still other sources can include traffic managers, construction managers, or mobile device customers responsible for individual mobile devices or fleets of mobile devices, which can provide input to the automated controller. Such input can include requests for routes or mobile device service, schedules of expected conditions, notifications of emergencies, etc. The network controller can be provided and configured to obtain indications from traffic monitoring devices. The network controller can then allocate wireless communication resources for use by the traffic monitoring devices to communicate with the automated controller. For example, the network controller can be part of the wireless communication network infrastructure.

[0065] Traffic managers can provide traffic management information, traffic status information, or both. This can include information related to congestion, construction, the appearance of obstacles, breakdowns or collisions, etc. Traffic management conditions can be considered a type of operating condition provided by traffic managers.

[0066] Routes or their characteristics can be defined to avoid obstacles and to make room for higher priority routes or emergency vehicles. Different priority lanes can be defined for different categories of mobile devices, where less congested lanes are defined and accessed by higher priority mobile devices. Access to higher priority lanes can be restricted to manage congestion. Lanes of different widths can be defined so that mobile devices of different widths can be accommodated. The proportion of road allocated to mobile devices travelling in a first direction, relative to the proportion of road allocated to mobile devices travelling in a second direction opposite to the first direction, can be adjusted over time based on demand. As such, reversible lanes can be defined and managed. The definition of a route or characteristic (e.g. a virtual lane) can include a determination of a virtual lane by a controller. The determination can correspond to generating an indication of a virtual lane that travels along a physical road, avoids obstacles, makes room for other virtual or non-virtual lanes, accommodates a certain volume of traffic, etc. Various methods can be used to determine a virtual lane, for example, using an automated calculation system that implements physical traffic engineering principles accepted in the relevant jurisdiction.

[0067] In embodiments, in order to properly follow a route transmitted to a mobile device, it can be necessary for the mobile device to intermittently or continuously determine its geographic location with precision. The use of various technologies such as a geolocation system or a network-assisted positioning system can be used to facilitate such location determination. The navigation system of the mobile device determines its position relative to the route and causes the mobile device to navigate such that its position follows the route as closely as possible.

[0068] In some embodiments, a route can be dictated to a mobile device as a single defined route. In this case, the mobile device is configured to follow the defined route. In other embodiments, characteristics of a route to be followed are transmitted to the mobile device navigation system along with an indication of multiple routes or multiple types of routes. In this case, the mobile device navigation system is used to select one route or one type of route that exhibits the characteristics of the route described above, and then follow the selected route or type of route.

[0069] Embodiments of the present application provide an eROAD concept or system to overcome one or more limitations in the prior art.

[0070] Autonomous driving systems rely on sensors to obtain relevant and timely data needed to effectively navigate. However, sensors can generate data or even reliable data in all situations, particularly when driving conditions change. For example, a sensor used by an autonomous driving system to detect a road line can be unable to detect the line due to ice and snow covering the line. The same sensor can be unable to detect a road line due to lack of light needed by the sensor to detect the line, for example, in a tunnel. The operability or ability of such a sensor to detect a road line is very important to effective navigation by the autonomous driving system. Effective navigation by the autonomous driving system also depends on the response of the system to changing conditions, for example, effectively responding to sudden traffic congestion, whether due to an accident or due to merging traffic. Similarly, determining how to prioritize the use of a road in an emergency, for example, giving way to an ambulance and police car, also becomes relevant to effective navigation by the autonomous driving system.

[0071] Embodiments of the present application provide a transportation traffic navigation service, which can be referred to as an eROAD service. The eROAD service can be provided to vehicles, for example, autonomous or self-driving vehicles on physical roads, through the use of an eROAD map. The eROAD map can be a dynamic map that includes marked virtual lanes for guiding a navigation system of a mobile device. The eROAD map does not necessarily indicate traditional painted physical lanes. Rather, the eROAD map indicates virtual lanes that are defined only in the navigation system. This allows for more flexible use of physical roads. That is, lanes can be dynamically defined according to conditions and requirements. This can include lane width and lane path. Multiple lanes can be dynamically determined and defined in order to properly manage traffic in one or more directions in response to current conditions and requirements. The eROAD service can also obtain data from camera systems or other sources that provide real-time transportation traffic load monitoring. This allows the eROAD service to respond to current conditions and can further improve traffic management and road use optimization.

[0072] In embodiments, the eROAD map defined by the autonomous controller is the same eROAD map provided to subscribers. The subscribers can use the eROAD map as a basis to determine which route to follow (e.g., designated by the autonomous controller). The autonomous controller obtains input from other sources, such as monitoring devices or mobile devices, and determines whether to update (re-determine) the eROAD map or routes defined thereby in response to such input. The determination can be made based on various operational routines, optimizations, etc.

[0073] Devices employing autonomous driving systems, such as autonomous vehicles, can use the eROAD service to control their movement (speed and direction). To use the eROAD service, a device with access to the eROAD map can compare its current location to the location of a particular virtual lane. The virtual lane can be the nearest or most appropriate virtual lane location corresponding to a desired path or destination of the device, or otherwise assigned. The device can use various techniques, such as a geo-positioning system or a network-assisted positioning system, to obtain its current geographic location. Upon determining a virtual lane to pass through, the device can accordingly begin to navigate. This can involve navigating the device (e.g., by maneuvering the vehicle) such that the distance between the device and the virtual lane is minimized (e.g., substantially 0), and such that the direction of travel of the device is aligned with the direction of travel of the virtual lane.

[0074] Embodiments will now discuss the architecture and functionality of the eROAD system.

[0075] Figure 1 The overall architecture of the eROAD system according to embodiments of the present application is shown. Referring to Figure 1 , the eROAD system 100 includes an eROAD controller 102 and registered eROAD subscribers 108. The eROAD controller 102, which can also be referred to as an autonomous controller, operates in or is coupled with network infrastructure and wirelessly communicates with other network entities including devices such as autonomous vehicles. As such, one or more of the illustrated interactions 107, 109, 111, 113 can be performed via the wireless access network 104. The eROAD controller 102 is responsible for obtaining or receiving various information indicative of the current operating conditions of physical roads. The autonomous controller 102 can also be used to determine or create eROAD maps as needed in response to requests for eROAD services by the eROAD subscribers 108. The autonomous controller 102 can determine or create one or more eROAD maps based on at least the current operating conditions, pre-existing data, or both. The autonomous controller 102 can also be used to transmit the created eROAD maps to devices such as the eROAD subscribers 108. The autonomous controller 102 can transmit the one or more determined or created eROAD maps to the eROAD subscribers 108 through broadcast messages, multicast messages, or unicast messages.

[0076] In operation, the autonomous controller 102 interfaces with other system entities including the eROAD service customers 110, the eROAD service subscribers 108, the road managers 112, the monitoring systems 106 including transportation traffic monitoring devices, monitoring system managers or monitoring system management functions, and the wireless access network 104.

[0077] According to embodiments of the application, the automated controller 102 can interface 111 with one or more service customers 110, which can include owners of one or more mobile devices that can use the eROAD service or entities responsible for the one or more mobile devices. The service customers 110 can request the eROAD service from the automated controller 102. The request can include a requested level of service. The service customers 110 can send information to the automated controller 102 in the request. The information can include one or more of the following: a number of mobile devices; information identifying the mobile devices, such as model and year; a planned route and schedule; and preferred quality of service requirements. The automated controller 102 can determine a level of service based on the information obtained from the service customers 102 and other information indicative of operating conditions. The automated controller 102 can create an eROAD map including routes (virtual lanes) based on the determined level of service, the obtained information, and the other information indicative of operating conditions. The automated controller 102 can respond to the service customers 110 using the determined level of service included in instructions or policies. The instructions or policies are then implemented by the service customers 110. The automated controller 102 can include the created eROAD map in the response. The service customers 110 can configure their mobile devices based on the instructions or policies obtained from the automated controller 102.

[0078] In some embodiments, the service customers communicate with the controller without the support of a wireless connection or access network. For example, the customer can send a list of possible subscribers to the controller, and there can be subscribers that are not on the list. The subscriber can still register and / or subscribe to the controller for service. In one embodiment, the controller can reject registration of a device even if the device is on the list sent by the customer. That is, the device can need to register without necessarily requiring information from the customer. In another example, the customer can have the ability to register subscribers with the controller. That is, the registration can occur via an interface separate from the interface used to transmit eROAD maps and routes to the mobile device navigation system.

[0079] According to embodiments of the present application, the automated controller 102 can interface 109 with eROAD service subscribers 108, which can represent one or more mobile devices. The service subscribers 108 can register or subscribe to the eROAD service by sending a request to the automated controller 102. In the request, the service subscribers 108 can include one or more of, for example: an identification of the device or vehicle, such as a model of the device or vehicle; a requested quality of service or level of service or both; a planned route and schedule; and other relevant information. Upon receiving the request, the automated controller 102 can determine a level or quality of service based on the information obtained in the request. The automated controller 102 can then assign or associate the level or quality of service to the subscriber's device. Routes can also be associated with a level of service quality, such that a mobile device requires a level of service quality at least as good as the level of service quality of the route in order to use the route. The automated controller 102 can generate an eROAD map and a corresponding usage policy (also referred to as a level of service policy) according to the determined level of service, the information obtained in the request, and other obtained information. The map can be dynamically adjusted based on the road conditions, with updates being sent to the service subscribers accordingly. The usage policy can indicate which routes and virtual lanes the subscribers 108 are allowed to use, a valid time window for the usage, and other usage criteria, such as speed and vehicle carrying requirements. The usage policy can be periodically updated according to changes in road conditions, allowing the mobile devices of the subscribers to effectively respond to the changing conditions. In some embodiments, the transmission of the eROAD map can be encrypted, and the automated controller 102 can also provide the service subscribers 108 with a key for decrypting the eROAD map. The usage policy can be transmitted as a property of the route.

[0080] After decrypting the eROAD map (if necessary), the service subscribers 108 can implement the usage policy and start using the eROAD map. As the automated controller 102 periodically obtains information indicative of road conditions, the automated controller 102 can update the usage policy provided to the service subscribers 108, which can accordingly implement the updated usage policy.

[0081] Similarly, the service subscribers 108 can periodically obtain information related to changing road conditions during their travel. The service subscribers 108 can report events related to the changing road conditions to the automated controller 102.

[0082] According to embodiments of the application, in providing eROAD services including development and periodic updates of eROAD maps, the automated controller 102 can interface 113 with a manager 112 for road operations or road construction. The road manager 112 can send information to the automated controller 102 indicating current road conditions. The information sent by the road manager 112 can include indications of physical layout, scheduled road maintenance or construction events, road quality, weather related road conditions and corresponding speed limits, and permitted uses. This information can include events reported to the road manager 112 by other road entities. The automated controller 102 can use the acquired information to adjust the eROAD maps provided to the subscribers 108. The automated controller 102 can also send indications of events reported by the subscribers 108, such as accidents, potholes, and other road conditions, to the road manager 112, which can be used to inform the road manager 112 of required maintenance, construction, or both. The automated controller 102 can also send information related to proposed schedules for road maintenance, construction, or both, to the road manager 112 based on traffic conditions.

[0083] According to embodiments of the application, the automated controller 102 can interface 107 with a monitoring system 106 including (e.g., fixed) traffic monitoring devices or a monitoring system manager (management function). The automated controller 102 can acquire one or more reports including monitoring results. The reports can be acquired upon request. The reports can be acquired from the monitoring devices or the monitoring system management function of the monitoring system 106. In some embodiments, the monitoring system 106 can periodically send one or more reports including monitoring results. The monitoring results sent by the monitoring system 106 can be related to one or more of the following changing traffic conditions: existing and predicted congestion zones; existing and predicted congestion time periods; lane usage and available lanes for mitigating traffic congestion; periodic traffic load status results; triggering of one or more predefined conditions, thresholds, or both; and other related changing traffic conditions. The automated controller 102 can interact with monitoring devices such as registered road-side cameras and periodically acquire monitoring data.

[0084] According to embodiments of the application, different components in the eROAD system 100 can communicate with a wireless access network 104 through the interface 105. The wireless access network 104 can provide network resources to the eROAD system 100 to enable the automated controller 102 to communicate with the service subscribers 108 and the monitoring devices. The wireless access network 104 can exclusively use network slicing to provide communication services to the eROAD system 100.

[0085] Figure 2A process for providing eROAD maps, registering service subscribers, and reporting events via a wireless access network according to embodiments of the present application is shown. Referring to Figure 2 At step 202, the automation controller 102 can provide an encrypted eROAD map to the service subscriber 108 periodically or on-demand via the wireless access network 104. The automation controller 102 can also include the usage policies and encryption keys discussed elsewhere herein in the encrypted eROAD map. The wireless access network 104 can obtain the encrypted eROAD map from the eROAD controller 102 and can broadcast, multicast, or unicast the obtained map to the service subscriber 108 periodically or on-demand. The obtained encrypted eROAD map can be provided in response to a request for eROAD services by the service subscriber 108. The request can include information discussed above and elsewhere herein.

[0086] Referring to Figure 2 At step 204a, a new service subscriber 108 can register for eROAD services by requesting eROAD services from the automation controller 102, where the request includes information identifying the mobile device of the subscriber, the planned path and schedule of the mobile device, and other information discussed elsewhere herein. The service subscriber 108 can send the request to the automation controller 102 via the wireless access network 104, which relays the request to the automation controller 102. At step 204b, the automation controller 102, having obtained the registration information of the service subscriber, can respond accordingly via the wireless access network 104. The response can be a positive response to register the service subscriber, or a negative response to reject the registration. The positive response can include one or more of an encrypted eROAD map generated based on the registration information of the subscriber, the usage policies for the eROAD map, and the encryption keys discussed with reference to step 202 and elsewhere herein.

[0087] Referring to Figure 2At step 206a, the service subscriber 108 can report an event to the automated controller 102 through the wireless access network 104, as discussed elsewhere herein. The service subscriber 108 can report the event to the automated controller 102 when a predefined threshold is triggered. The automated controller 102 can multicast, broadcast or unicast the reported event to one or more of the other service subscribers 108 accordingly at step 206b. The wireless network 104 forwards messages between the service subscriber 108 and the automated controller 102. As described herein, when a wireless network is designated to perform an action, or when a communication is designated to occur via a wireless network, it should be understood that the aforementioned action can be performed via a node in the wireless network, or the aforementioned communication can occur via a node in the wireless network. The node can be an access network (AN) node with wireless communication capability.

[0088] The wireless network can be used to facilitate various communication operations with the controller, e.g., with mobile devices, subscribers, monitoring devices, road managers, or a combination thereof. In some embodiments, some or all of the communication operations can be conducted using specific allocated resources. For example, wireless resources can be dedicated to certain communication operations, such as reporting from monitoring devices, transmission of virtual lanes to mobile devices, etc., or a combination thereof.

[0089] Figure 3 A process for communicating between an automated controller and a monitoring system (device) via a wireless access network according to embodiments of the present application is shown. Reference is made to FIG. 3. Figure 3 At step 301a, the monitoring system 106 can register with the automated controller 102 by sending a registration request. At step 301b, the automated controller 102 can send a response to the monitoring system 106 indicating that the monitoring system 106 has registered or has not registered.

[0090] At step 302, the monitoring system 106 can collect information indicative of transportation traffic load, road conditions, or both. For example, such information can include camera images or data. The monitoring device can be preconfigured or periodically provisioned with network resources to communicate with the automated controller 102. The monitoring device 106 can report or send the collected information to the automated controller 102.

[0091] Figure 4 An exemplary eROAD map including an eROAD with two virtual lanes according to embodiments of the present application is shown. Reference is made to FIG. 4. Figure 4, eROAD 480 can use the physical road defined by roadways curb boundaries 402 and 404. eROAD 480 can include virtual lanes 482 and 484, which can be represented by virtual lines, virtual line 1 and 2 corresponding to lanes 482 and 484, respectively. Virtual lines 1 and 2 can be defined or described by a series of location points 486 (represented as circles) with coordinates along the physical road. Each virtual line can have a corresponding usage policy that includes a quality of service level identifier (ID). Quality of service can be determined in various ways. For example, quality of service can be defined according to an emergency level, such as a high level, an intermediate or medium level, a normal level, or a low level, etc. Service level can also be determined according to a speed level requirement, for example, level 1 speed can correspond to a speed greater than 300 km / hour, level 2 speed can correspond to a speed range between 250 km / hour and 300 km / hour, etc. Quality of service level can be determined according to a range of width that a mobile device is allowed to traverse a route. For example, a lane can have a predetermined width, and vehicles up to a certain width are allowed. eROAD maps are dynamic maps that can change according to one or more of physical road layout, changing traffic and road conditions, or subscriber quality of service requirements, as will be further discussed elsewhere herein. Mobile devices subscribing to eROAD services can be assigned an eROAD map that includes a route corresponding to the mobile device requirements, as discussed elsewhere herein. For example, vehicle 488 can be assigned an eROAD map that indicates the vehicle's route to be virtual line 1 corresponding to first virtual lane 482. Vehicle 488's route is defined by physical location markers, which can be location points with coordinates 486. After obtaining its route, vehicle 488's navigation system can be used to monitor vehicle 488's physical location and guide vehicle 488 to travel along the series of location markers defined by the eROAD map. Similarly, vehicle 490 can be assigned an eROAD map that indicates the vehicle's route to be virtual line 2 corresponding to second virtual lane 484. Vehicle 490's navigation system can be used to monitor the vehicle's physical location and guide the vehicle to travel along its route.

[0092] In some embodiments, each lane or each line on the eROAD map belongs to or is associated with one or more classifications. Each classification corresponds to one or more characteristics of the lane or line. In some embodiments, the classifications include one or more characteristics such as speed limit, quality level, lane sharing allowance, width size, lane ID or line ID, etc. The mobile device can select a lane or line from a plurality of presented alternative lanes or lines by matching the received characteristics to at least one specific classification and selecting one or more lanes or lines from the set of lanes or lines that belong to the specific classification. Different lanes or lines can have certain classifications, and in order to use the lane or line, the mobile device should have an indication to use the lane or line characteristics corresponding to these classifications. The lane characteristics can be transmitted to the mobile device by the automated controller.

[0093] In various embodiments, an eROAD map defining a plurality of possible lanes (e.g., lanes or lines) is provided. Each lane can be associated with certain characteristics such as width, quality of service, speed range, etc. A mobile device receiving the eROAD map can then select one of the lanes to follow based on this information. The lane should be such that the mobile device meets any requirements associated with the characteristics. For example, the mobile device should have a width that is narrow enough, be explicitly authorized to receive the quality of service, travel within the specified speed range.

[0094] In some embodiments, the eROAD map includes other information to simulate a vertical traffic light at a physical intersection. The physical intersection can be represented by a location marker on the eROAD map. The location marker can be associated with a stop time window, for example, 0 seconds to 30 seconds. Within the stop time window, a mobile device at the location marker needs to be at 0 speed, i.e., stop as if at a red traffic light. Accordingly, once the mobile device reaches the physical intersection represented by the location marker on the eROAD map, the navigation system of the mobile device can check the current time and control its speed so that the mobile device does not pass the location marker within the stop time window. This can require the mobile device to slow down or stop before or at the location marker. For example, a mobile device arriving at a location marker at 2:31:13 PM with a stop time window starting at 2:31:00 PM and lasting until 2:31:30 PM, can stop at the location marker until 2:31:30 PM and then start moving again (e.g., then turn left at the intersection).

[0095] In some embodiments, the automated controller can configure virtual traffic control signals to control traffic at an intersection involving at least one of the virtual lanes. The automated controller can also transmit an indication of the virtual traffic control signals to the vehicle(s), user(s), or mobile device 108. The virtual traffic control signals can be transmitted and associated with a location marker representing the physical intersection, as described above. The virtual traffic control signals can simulate vertical traffic lights at the intersection, as described above.

[0096] In some embodiments, the eROAD map includes other information for controlling lane changes. This can allow a mobile device to switch between multiple virtual lanes defined on the eROAD map. The lanes can be marked or updated by one or more location markers. Each of these location markers is associated with a (e.g., 1-bit) "lane change" flag. This flag can be set to indicate that a lane change is allowed at that location marker. Otherwise, if the flag is not set, then a lane change is not allowed at that location marker. A mobile device reaching a location marker with the "lane change" flag set can make a lane change at its own discretion.

[0097] In embodiments, a virtual lane or a virtual line that is part of a virtual lane can include a list of location coordinates to follow. A vehicle following the virtual line can navigate between successive coordinates in the list, e.g., by driving from one coordinate to the next in a substantially straight manner. The virtual line does not necessarily have to be a straight line, but refers to an arbitrary shaped path. The selected coordinates can be marked with an indication that allows a mobile device to transform between virtual lanes at such coordinates. This allows a mobile device to perform semi-automated navigation by selecting a desired virtual lane while controlling the manner in which lane changes are allowed. This allows for traffic control.

[0098] Figure 5A 、 Figure 5B 、 Figure 5C and Figure 5D An exemplary eROAD according to embodiments of the present application is shown. An eROAD can be defined as a physical road having one or more virtual lanes included as part of an eROAD map. The virtual lanes can be dynamically adjusted during use, e.g., to provide a changed lane width or to avoid obstacles.

[0099] One or more of the virtual lanes can have a specified width to accommodate a predetermined size of mobile device. One or more of the virtual lanes can be associated with one or more specific quality of service or level of service, such as an emergency level or a required speed level. Accordingly, one or more of the lanes can be prioritized according to traffic conditions and road conditions. Similarly, the width, length, and direction of travel of one or more of the virtual lanes can be adjusted according to changing traffic conditions. As such, an eROAD including one or more virtual lanes can represent at least a portion of a physical road. Limiting use of a physical road to certain portions of the physical road during road maintenance and construction is particularly useful. Determining which portions of a physical road can be used through eROADs or virtual lanes can reduce the time and resources required to block off using traffic cones, barricades, and other human and physical resources. An eROAD map can be automatically generated based on scheduled maintenance and / or road construction provided by the road manager 112 to the automated controller 102, as described elsewhere herein.

[0100] Figure 5A An exemplary eROAD including lanes with the same quality of service and width is shown in accordance with embodiments of the application. Referring to Figure 5A An eROAD 400 having physical road side boundaries 402 and 403 can include virtual lanes 406 and 408. These lines determine the routes to be taken by mobile devices. Lanes 406 and 408 have the same width, indicating that mobile devices 409, 410, and 411 can use these lanes can have up to the allowed width or a certain width determined according to the lane width. The direction of lanes 406 and 408 can be the same or opposite, and can change according to changing traffic conditions and road conditions.

[0101] According to traffic conditions and road conditions, lanes 406 and 408 can need to change to accommodate larger size mobile devices that are not allowed to use the lanes. Accordingly, eROAD 400 can need to be adjusted to more effectively respond to changing traffic conditions and road conditions.

[0102] Figure 5B An exemplary eROAD including lanes with different widths is shown in accordance with embodiments of the application. Referring to Figure 5BeROAD 414 may include virtual lanes 416 and 418 with different widths. Lane 416 may have a wider width compared to lane 418, thereby limiting use of lane 416 to larger mobile devices 420. Similarly, lane 418 may have a narrower width compared to lane 416, thereby limiting use of lane 418 to smaller mobile devices 422. In some embodiments, the virtual lane may be defined using a single line indicating the center of the virtual lane, optionally accompanied by a width parameter indicating the width of the virtual lane. In other embodiments, the virtual lane may be defined using a pair of lines indicating the left and right boundaries of the virtual lane.

[0103] Figure 5C An exemplary eROAD for alleviating traffic congestion according to an embodiment of this application is shown. Reference Figure 5C eROAD 430 may include virtual lanes 432 and 434. Mobile device 435 is a subscriber whose route has been assigned lane 432 according to their eROAD map and has just experienced traffic congestion along their route. Mobile device 435 can collect transportation data related to the experienced traffic congestion, such as... Figure 3 As described in step 302. Then, the mobile device 435 can report the traffic event to the monitoring system 106, the automatic controller 102, or both. The mobile device 435 can, according to... Figure 2 Step 206 in the process involves reporting an event. A traffic event may include determining a coordinated location point of congestion zone 450. If mobile device 435 only reports a traffic event to monitoring system 106, monitoring system 106 forwards the event to automatic controller 102 and other system entities, including other mobile device subscribers 108. In some embodiments, monitoring system 106 can, according to... Figure 3 In step 302, data is collected and transmitted to the automatic controller 102, which may indicate, for example, congestion zone 450.

[0104] The automatic controller 102 can then respond to changing traffic conditions, i.e., congested areas, and update the eROAD map for the user subscriber with the same route as mobile device 435, which is lane 432. The automatic controller 102 can then execute the updated eROAD map. Figure 2In step 202, the updated eROAD map is provided to mobile device 436. Accordingly, mobile device 436, which may have the same route as mobile device 435, will receive the updated eROAD map, which indicates or suggests changing the route of mobile device 436 from lane 432 to lane 434. This indication may include the appropriate location coordinates 438 where mobile device 436 should (or is permitted) change its route from lane 432 to lane 434, thereby preventing mobile device 436 from passing through congestion zone 450 and further reducing congestion zone 450. The navigation system of mobile device 436, having received the updated route, can generate a result that causes the mobile device to change its route based on the changed route. For example, the navigation system can notify the driver via the mobile device's display of the anticipated congestion zone and at which point on the route the driver should change their route.

[0105] Figure 5D An exemplary eROAD for an emergency lane is shown according to an embodiment of this application. Reference Figure 5D eROAD 460 may include lanes 462 and 464. Mobile device 466 may correspond to a subscriber of the eROAD service that has been assigned an emergency level. Automation controller 102 has an indication of the route of mobile device 466 (i.e., lane 462). Automation controller can accordingly determine that a route change from lane 462 to 464 may be more efficient for the service level of mobile device 466. Automation controller 102 can learn the higher priority service level of mobile device 466 by receiving input from mobile device 466, which indicates the service priority level at an earlier time point, such as location point coordinate 467. Accordingly, automation controller can determine that at that location, mobile device 466 should change its route from lane 462 to the appropriate location point coordinate 468 at location point coordinate 470 on lane 464, thereby making the route more efficient. Automation controller 102 can then update the eROAD map of mobile device 466, including the new route, and notify mobile device 466. Accordingly, the navigation system of the mobile device 466, having obtained the updated route, can generate a result that causes the mobile device to change its route based on the changed route. For example, the navigation system can notify the driver via the mobile device's display that a faster route is available and at what point on the route the driver should change their route.

[0106] Embodiments of the application can be implemented in electronic hardware, software, or combinations thereof. In some embodiments, the application is implemented by one or more computer processors executing program instructions stored in a memory. In some embodiments, the application is implemented partially or entirely in hardware, e.g., using one or more field-programmable gate arrays (FPGAs) or application-specific integrated circuits (ASICs) to perform processing operations quickly.

[0107] Figure 6 For a schematic diagram of an electronic device 600 according to different embodiments of the application, the electronic device can perform any or all of the operations of the above-described methods and features explicitly or implicitly described herein. For example, a computer equipped with network functionality can be configured as the electronic device 600.

[0108] As shown, the device includes a processor 610 such as a central processing unit (CPU) or specialized processors such as graphics processing units (GPUs), or other such processor units, a memory 620, a non-transitory mass storage device 630, an input output interface 640, a network interface 650, and a transceiver 660, all of which are communicatively coupled via a bidirectional bus 670. According to certain embodiments, any or all of the described elements can be used or merely a subset of the elements are used. Further, the device 600 can have multiple instances of certain elements, such as multiple processors, multiple memories, or multiple transceivers. Further, elements of the hardware device can be coupled directly to other elements without a bidirectional bus. Additionally or alternatively, other electronics besides a processor and memory can be employed to perform the required logical operations.

[0109] The memory 620 can include any type of non-transitory memory, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous DRAM (SDRAM), read-only memory (ROM), or any combination of these or other non-transitory memories.

According to certain embodiments, the memory 620 or mass storage device 630 can have recorded thereon statements and instructions executable by the processor 610 for performing any of the above-described method operations.

[0110] Figure 7A and Figure 7B A method for facilitating navigation of a mobile device operatively coupled to a wireless network is shown according to embodiments of the application. Reference is made to Figure 7AAt step 702, the automated controller 102 obtains input from other system entities. The input indicates the current operating conditions of the physical roadway. As described elsewhere herein, the monitoring system 106 (any one or more of the devices, managers, or management functions) can send information related to the current operating conditions to the automated controller 102. Similarly, the roadway manager 112 and the eROAD customer 110 can also send information to the controller 102 indicating the current operating conditions. In some embodiments, the input indicating conditions on the physical roadway can be received from a manager responsible for managing the physical roadway, such as the roadway manager 112, and the input can include one or more of: the physical layout of the roadway; the quality of the roadway; and weather-related roadway conditions. Service subscribers can also report events to the automated controller 102, the events indicating the current operating conditions.

[0111] In some embodiments, the current operating conditions include transportation requirements of the mobile devices. The transportation requirements of the mobile devices include one or more of: a required speed, a required schedule, a required route, and a priority level. For example, referring to Figure 5B In comparison to the mobile device 422, the mobile device 420 can require a larger lane size. Accordingly, each mobile device can transmit its size requirements to the automated controller 102. Similarly, the mobile device 466 can require a level of emergency service, which will be transmitted to the automated controller 102.

[0112] In some embodiments, the current operating conditions include one or more of traffic conditions on the physical roadway, or traffic state information associated with the physical roadway, which can include one or more of: a traffic congestion condition, an occurrence of an obstruction, and requirements to accommodate one or more higher priority mobile devices. For example, referring to Figure 5C The mobile device 435, which has passed through the congestion zone 450, will report the experienced traffic congestion to the automated controller 102. Similarly, Figure 5D The mobile device 466, which has a higher priority level of service, will transmit its higher priority level of service to the automated controller 102 to provide a more efficient route.

[0113] In some embodiments, the automated controller 102 can receive traffic state information from one or more fixed monitors deployed along the physical roadway, such as the monitoring system 106. In some embodiments, the traffic state information can be determined based on information from one or more monitors, and the conditions can indicate traffic conditions on the physical roadway. The traffic state information can include one or more of the traffic congestion conditions and the occurrence of an obstruction discussed herein.

[0114] At step 704, the automated controller 102 determines (e.g., defines) a route along the physical roadway based at least in part on the inputs described above, and the route is to be followed by the mobile device. Exemplary embodiments of the automated controller 102 defining a route are discussed elsewhere herein, including with respect to Figure 5A , Figure 5B , Figure 5C and Figure 5D described above. The automated controller can determine one or more routes in this manner. Each of the one or more routes can include a respective virtual lane along the physical roadway that defines the respective route, and the mobile device is to follow at least one of the virtual lanes.

[0115] In some embodiments, the current operating conditions are reported to the automated controller 102 via the wireless network 104 based on information generated by one or more of: the mobile device on the physical roadway, a monitoring device (monitoring system 106) deployed along the physical roadway, a customer of the mobile device for travel on the physical roadway, and a manager of the physical roadway (road manager 112). Exemplary embodiments are discussed elsewhere herein, including with respect to step 202 in Figure 2 and step 302 in Figure 3 described above with respect to gathering data indicative of the current operating conditions on a regular or on-demand basis.

[0116] At step 706, after determining the route for the mobile device, the automated controller transmits the route (e.g., one or more virtual lanes) to the navigation system of the mobile device via the wireless network. Exemplary embodiments of transmitting the route to the navigation system of the mobile device are discussed elsewhere herein, including with respect to Figure 5C described above with respect to releasing the mobile device 436 from the congested zone 450. Other embodiments of transmitting the route are discussed elsewhere herein, including with respect to Figure 5D described above with respect to updating the route of the mobile device 466 from lane 462 to lane 464.

[0117] In some embodiments, an indication of the determined route (one or more virtual lanes) can be transmitted to the mobile device. In some embodiments, the indication of the determined one or more virtual lanes can include one or more usage requirements for at least one of the virtual lanes. The usage requirements may, for example, indicate which criteria the mobile device needs to satisfy in order to use the virtual lane. Such criteria can include a vehicle width criterion, a minimum or maximum speed, a priority level, and the like.

[0118] In some embodiments, the route transmitted at step 706 is transmitted as part of a dynamically updated map, the part including the route through the physical road. Exemplary embodiments of routes transmitted as part of a dynamic map, i.e. an eROAD map, have been discussed throughout the disclosure, particularly in Figure 2 step 202 of Figure 5C releasing the mobile device 436, and Figure 5D providing emergency level service in

[0119] In some embodiments, the map transmitted to the subscribing mobile device defines parallel lanes through the physical road. Each lane can be dynamically updated according to changing operating conditions of the physical road. Exemplary embodiments are discussed elsewhere herein, including with reference to Figure 5A wherein lanes 406 and 408 are defined for mobile devices of the same size, and Figure 5B lanes 416 and 418 are defined for mobile devices of different sizes. Accordingly, the input acquired by the automated controller 102 can indicate that the current operating conditions of the physical road require a change in lanes to accommodate mobile devices of different sizes. If so, the automated controller 102 can dynamically update the map, and can adjust the lane widths accordingly.

[0120] In some embodiments, the route defined by the automated controller 102 is represented as a line on the dynamically updated map. The line can be represented as a set of geographic point locations. Exemplary embodiments are discussed elsewhere herein, including with reference to Figure 4 , Figure 5A , Figure 5B , Figure 5C , Figure 5D wherein the route is represented as virtual lines 1 and 2 in each corresponding map.

[0121] In some embodiments, at step 708, the navigation system of the mobile device that has acquired the route from the automated controller can generate an output that causes the mobile device to follow the route. For example, the output can include steering control signals. In some embodiments, the step of transmitting the route at step 706 includes transmitting a series of physical location markers or coordinates along the route (e.g. in the form of a virtual line to be followed). In some embodiments, the navigation system is used to monitor the physical location of the mobile device, and to guide the mobile device to travel along the series of physical location markers. Exemplary embodiments are discussed elsewhere herein, including with reference to Figure 4 wherein the route of the mobile device 488 is defined by a series of physical location markers, which can be the location point coordinates 486, and the navigation system of the mobile device monitors the physical location of the mobile device and guides the mobile device to travel along its route.

[0122] In some embodiments, the route defines a lane to be followed by a plurality of successive mobile devices, the lane being substantially free of physical obstacles and not intersecting one or more other lanes along the physical roadway. In some embodiments, the route is determined to provide the lane with at least a specified width to accommodate a predetermined size of mobile device. For example, Figure 5A The lane 406 determines a route to be followed by the mobile devices 409 and 413, which can have the same service priority and size requirements.

[0123] Similarly, in some embodiments, the route is dynamically defined such that the lane avoids physical obstacles on the physical roadway, or such that the lane avoids intersecting one or more other dynamically defined lanes along the physical roadway.

[0124] In some embodiments, at step 710, the automated controller 102 can define, based at least in part on the input obtained, a second route along the physical roadway to be followed by a second mobile device. In some embodiments, at step 712, the automated controller 102 can transmit the second route to a navigation system of the second mobile device via a wireless network. In some embodiments, the route defines a first virtual lane to be followed by a plurality of mobile devices, the first virtual lane being substantially free of physical obstacles and not intersecting one or more other lanes along the physical roadway. In some embodiments, the second route defines a second virtual lane to be followed by a plurality of other mobile devices, the second virtual lane being substantially free of physical obstacles and not intersecting one or more other lanes along the physical roadway, including the first virtual lane. Exemplary embodiments are discussed elsewhere herein, including with reference to Figure 5A The lane 406 is defined as a route for the mobile devices 409 and 413, and the lane 408 is defined as a route for the mobile devices 410 and 411. The first route as the virtual lane 406 is substantially free of physical obstacles, and the second route as the lane 408 is also substantially free of physical obstacles and does not intersect one or more other lanes along the physical roadway, including the first lane 406.

[0125] In some embodiments, the automated controller can dynamically adjust one or more virtual lanes in response to further input obtained after the input at 702, the further input indicating one or more of: a subsequent condition on the physical roadway, a subsequent traffic state information associated with the physical roadway, and a subsequent requirement of a mobile device.

[0126] In some embodiments, the automated controller can configure virtual traffic control signals to control traffic at intersections involving at least one of the virtual lanes described above. The automated controller can also transmit indications of the virtual traffic control signals to the vehicle(s), user(s), or mobile device 108. The automated controller can implement the virtual traffic control signals for the virtual lanes in a coordinated manner at points where multiple virtual lanes intersect. This allows vehicles to physically pass one another via the controlled intersections in a coordinated manner, with physical traffic lights being replaced by virtual traffic lights.

[0164] The eROAD scheme discussed in the embodiments herein can be useful and applicable to various future use cases of autonomous driving systems. For example, the eROAD system can be useful in cases of poor visual perception, especially when visual sensors or sensing are not available or can not be functioning properly, such as in bad weather or in tunnels.

[0165] Further, the eROAD system can be helpful in mitigating or alleviating traffic congestion, as discussed in the embodiments herein. The autonomous controller 102 can generate and broadcast eROAD maps to mobile devices on demand to enable the mobile devices to disengage from traffic congestion. The generated eROAD maps update the routes of the mobile devices by changing lanes at suitable locations along the physical road. Accordingly, the lanes represented by the lines on the eROAD maps can be automatically designed and flexibly implemented based on changing operating conditions to allow for efficient lane design for peak and off-peak hours, thereby avoiding and alleviating traffic congestion. Similarly, the eROAD system can help with temporary road construction by allowing temporary design of eROAD maps and automatically broadcasting them to mobile devices, thereby accommodating any road maintenance or construction. The navigation systems in the mobile devices can easily implement the new routes defined in the acquired temporary eROAD maps.

[0166] Further, the eROAD system can facilitate prioritization of different types of mobile devices for efficient navigation when the situation calls for it. For example, in the case of emergency services such as an ambulance, fire truck, or police car, the autonomous controller 102 can design a temporary eROAD map and multicast it to all relevant mobile devices to allocate a particular lane or a portion thereof to plan a route for the higher priority mobile device, while allocating separate other lanes for medium or lower priority mobile devices. Accordingly, the eROAD map can be designed to reflect the priority levels of the mobile devices.

[0167] In the various use cases discussed above, the mobile devices use the eROAD map by following the allocated route defined in the acquired eROAD map while monitoring their current locations to guide the mobile devices to travel along the allocated route.

[0168] It is noted that the eROAD system is not limited to autonomous cars, but is applicable to controlling path movement of robots and other similar devices that can use such a system.

[0169] To navigate a mobile device, such as a vehicle, to follow a defined route, it is desirable for the mobile device to have an indication of its location. Various location determination techniques can be used for this purpose, such as the global positioning system (GPS).
