[0021] In the present application, the multiple referred to herein means two or more. In addition, it should be understood that in the description of the present application, terms such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0022] First, a brief description of the related art will be given below:

[0023] Currently, users such as vehicle drivers or passers-by obtain road condition information from a traffic control center through a mobile network (Mobile web). The user needs to search for the road condition information of the area they want to know by themselves and filter out the road condition information of the areas they don't want to know. At the same time, the content of the road condition information is limited and independent of each other. For example, the road condition information only includes the traffic flow situation on the road, traffic control information, and vehicle accidents. The traffic flow situation, traffic control information, and vehicle accidents are independent of each other, and the user needs to associate the relationship between the three by themselves and analyze their own answers. For example, the user needs to query the traffic flow situation information, control information, and vehicle accidents separately, and then analyze whether the three parts of information occur within the same period of time.

[0024] Radio broadcasts can also play road condition information. The radio broadcasts adopt a way of alternating programs and road condition information. Users cannot obtain road condition information in a timely manner, and the road condition information may not be what the user wants to know.

[0025] In view of this, the embodiments of the present application provide a method for generating traffic information, a reminder method, a roadside device, a receiving terminal, and a traffic system.

[0026] Please refer to Figure 1 , Figure 1It is a schematic diagram of an application scenario of a traffic system. The traffic system 100 includes a traffic control center 10 and multiple roadside devices 20. The traffic control center 10 and one or more roadside devices are communicatively connected via wireless technology. For example, the wireless technology includes the 5th Generation Mobile Communication Technology (5G). The traffic control center 10 can be deployed on multiple servers. The traffic control center 10 has data storage and computing capabilities, and can be used to collect traffic information on each road section and send the traffic information to one or more roadside devices 20. The multiple roadside devices 20 are installed by the roadside. The roadside devices 20 also have data storage and computing capabilities, and can interact with the receiving terminal 30 for traffic information, having the function of a gateway. Communication between the roadside device 20 and the receiving terminal 30 can be carried out via Bluetooth technology. The receiving terminal 30 can be a vehicle 30 and / or an electronic device 30. The electronic device 30 can be a mobile phone, a smart watch, a laptop computer, etc. Among them, the traffic information can include traffic accident information and road condition information.

[0027] In some embodiments, the traffic system 100 further includes traffic signal devices 40 for directing the passage of pedestrians or vehicles. The traffic signal devices 40 include traffic lights. The traffic signal devices 40 can be used to send traffic light device information to the roadside devices 20.

[0028] Please refer to Figure 2 , Figure 2 It is a schematic flowchart of the method for generating traffic information according to an embodiment of the present application. The generation method can be applied in the traffic system 100, specifically, it can be applied to the roadside device 20. The generation method includes the following steps:

[0029] Step S101: Receive traffic accident information sent by the traffic control center.

[0030] The traffic control center 10 prestores the sending conditions of traffic accident information. The sending conditions include that after obtaining the traffic accident information of a certain road section, the information is sent to the roadside devices 20 of other road sections within the first preset range of this road section. For example, as Figure 1 shown, the sending conditions include that after obtaining the traffic accident information of section D, the information is sent to the roadside devices 20 of sections A, B, C, E, F, and D within the first preset range of this road section. One roadside device 20 can be set for multiple road sections, or one roadside device 20 can be set for one road section.

[0031] Traffic accident information includes the accident location, accident details, and resolution time, etc. Among them, the resolution time is the time when the accident is processed and the receiving terminal can pass. For example, the traffic accident information includes that the accident location is place a, the accident details are that two cars collided, and the resolution time is N hours.

[0032] Step S102: Determine the impact scope of the traffic accident according to the traffic accident information.

[0033] The impact scope refers to the scope that affects the driving of other means of transportation or the passage of pedestrians. The scope can be reflected by the road sections within the second preset range from the accident location. For example, taking place a as the accident location, sections E, B, D, and F are the impact scope. It can also be reflected by the area within the second preset range from the accident location. For example, the area includes sections E, B, D, and F, and the non-road sections near section F. It can be understood that the boundary shape of the preset range can be any shape such as a circle, rectangle, ellipse, etc.

[0034] The more serious the traffic accident information indicates the traffic accident is, the larger the impact scope. It can be understood that traffic congestion and traffic control and other road conditions may occur on the road sections leading to the accident location. If the accident is more serious, the sections with traffic congestion and traffic control will be longer, that is, the impact scope will also be larger.

[0035] Step S103: Obtain the road condition information within the impact scope.

[0036] The traffic control center 10 receives the road condition information sent by the road infrastructure or other terminals. The road infrastructure includes roadside devices 20 and road monitoring, etc. Other terminals include electronic devices 30 and vehicles 30, etc. The road condition information includes the road information and vehicle information sent by the roadside devices 20, vehicles 30, or road monitoring. The vehicle information includes vehicle speed, vehicle quantity, etc. The road information includes the road location. The road condition information also includes traffic control information, traffic law enforcement information, the maximum speed limit and minimum speed limit of each road section, etc. input by the operator or sent by the electronic device 30.

[0037] After the traffic control center 10 stores the road condition information of each road section, the roadside device 20 can obtain the road condition information within the impact scope from the traffic control center 10. For example, the roadside device 20 obtains the road condition information of sections E, B, D, and F from the traffic control center.

[0038] Step S104: In response to the appearance of a receiving terminal within the communication range, send the road condition information to the receiving terminal.

[0039] In one example, the roadside device 20 turns on Bluetooth broadcasting. When the receiving terminal 30 enters the Bluetooth broadcasting range, it sends the road condition information to the receiving terminal 30.

[0040] Please refer toFigure 3 , in an application scenario, on section D of a road, two vehicles 30 collide. Law enforcement officers report traffic accident information to the traffic control center 10 through electronic devices 30. After receiving the traffic accident information of section D, the traffic control center 10 sends the traffic accident information to the roadside device 20 on section F. The roadside device 20 determines the impact range of the traffic accident according to the traffic accident information. The impact range includes sections F and D. The roadside device 20 obtains the road conditions information of sections F and D from the traffic control center 10. At this time, the vehicle 30 enters the Bluetooth broadcast range of the roadside device 20, and the roadside device 20 sends the road conditions information of sections D and F to the vehicle 30. It can enable the receiving terminal 30 within the impact range to obtain the road conditions information from the accident location to the current location, so that users can make plans in advance and reduce the impact of traffic accidents. For example, users can change lanes in advance to avoid entering congested sections of the road.

[0041] It can be understood that after receiving the traffic accident information sent by the traffic control center 10, the roadside device 20 can determine the impact range of the traffic accident according to the traffic accident information, and then obtain the road conditions information within the impact range from the traffic control center 10. When a receiving terminal 30 appears within the communication range, it can send the road conditions information to the receiving terminal 30, so that the receiving terminal 30 can obtain the road conditions information that needs to be understood in a timely manner. It does not require users to search and filter out the road conditions information they want to know by themselves, saving time and manpower. At the same time, since the impact range of the traffic accident is determined and the road conditions information within the impact range is obtained after receiving the traffic accident information, the road conditions information is obtained after the traffic accident occurs, and the road conditions information can reflect the real-time impact of the traffic accident.

[0042] In some embodiments, determining the impact range of the traffic accident according to the traffic accident information includes the following steps:

[0043] Step S201: Determine the distance section between the traffic accident location and the roadside device.

[0044] The distance section refers to the section between the traffic accident location and the roadside device 20. The traffic accident information also includes the distance section. The traffic accident location refers to the place where vehicles or pedestrians cannot pass due to the occurrence of a traffic accident. The traffic accident location may include the accident site and the affected areas around the accident site. The affected area refers to the place affected by the accident site. For example, at the accident site, the vehicles 30 collide, and the fragments of the vehicles 30 fly to a certain place, resulting in damage to the road infrastructure at that place, or the road is damaged and cannot be passed, and that place is the affected area.

[0045] Step S202: Determine that the distance section is the impact range of the traffic accident.

[0046] As described above, the impact range can be represented by a section of the road. As Figure 3As shown, section F and section D are the distance sections between the roadside device 20 and the accident sending location, and section F and section D can be determined as the affected range.

[0047] It can be understood that the distance section between the accident location and the roadside device 20 may include the section leading to the accident sending location. Since traffic congestion and traffic control and other road conditions may occur on the section leading to the accident sending location. Therefore, after determining the distance section as the affected range, the roadside device 20 can obtain the road condition information of the distance section and send it to the receiving terminal 30 within the communication range. The receiving terminal 30 can timely understand the road condition information of the section between the accident location and the roadside device 20.

[0048] In some embodiments, determining the affected range of a traffic accident according to traffic accident information includes the following steps:

[0049] Step S301: Obtain a dynamic section according to the settlement time of the traffic accident.

[0050] It can be understood that as the severity of the traffic accident increases, the time required to handle the traffic accident and resume traffic is also longer, that is, the settlement time is also longer. Therefore, a dynamic section can also be calculated according to the settlement time. For example, as Figure 1 shown, the calculated dynamic section may be section D and section F, or may be section D, section F and section E. Among them, the longer the settlement time, the longer the dynamic section.

[0051] Step S302: Determine the dynamic section as the affected range of the traffic accident.

[0052] As Figure 2 shown, when the dynamic section is section D and section F, the affected range of the traffic accident is section D and section F. When the dynamic section is section D, section F and section E, the affected range of the traffic accident is section D, section F and section E.

[0053] It can be understood that by introducing the settlement time, the affected range of the traffic accident can be dynamically determined, so that users within the dynamic affected range can all receive the road condition information that needs to be understood.

[0054] In some embodiments, determining the affected range of a traffic accident according to traffic accident information further includes the following steps:

[0055] Step S401: Determine the distance section between the traffic accident location and the roadside device.

[0056] Step S402: Determine a dynamic section according to the settlement time of the traffic accident.

[0057] Step S403: Determine the affected range of the traffic accident according to the distance section and the dynamic section.

[0058] In one embodiment, if the length of the dynamic section is greater than that of the distance section, the dynamic section is determined as the influence range of the traffic accident. For example, if the distance sections are section D and section F, and the dynamic section is section D, section F, and section E, it indicates that the length of the dynamic section is greater than that of the distance section, then section D, section F, and section E are the influence range of the traffic accident.

[0059] In another embodiment, if the length of the dynamic section is less than or equal to that of the distance section, the distance section is determined as the influence range of the traffic accident. For example, if the distance sections are section D, section F, and section E, and the dynamic section is section D and section F, it indicates that the length of the dynamic section is less than that of the distance section, then the distance sections D, F, and E are the influence range of the traffic accident.

[0060] It can be understood that when determining the influence range, the distance from the traffic accident occurrence location to the roadside device 20 and the solution time of the traffic accident can be comprehensively considered. The influence range can be greater than the distance from the traffic accident occurrence location to the roadside device 20, and the influence range changes dynamically with the change of the solution time.

[0061] Please refer to Figure 3 , in an application scenario, on section D, two cars collided. After receiving the traffic accident information, the roadside device 20 determines that the distance sections between the traffic accident occurrence location and the roadside device 20 are section D and section F, and calculates the dynamic section as section D, section F, and section E according to the solution time of the traffic accident. The roadside device 20 determines the influence range as the dynamic section, that is, section D, section F, and section E. The roadside device 20 obtains the road condition information of section D, section F, and section E from the traffic control center 10. At this time, the vehicle 30 enters the Bluetooth broadcast range of the roadside device 20, and the roadside device 20 sends the road condition information of section D, section F, and section E to the vehicle 30.

[0062] In some embodiments, the generation method further includes the following steps:

[0063] Step S501: Obtain the device information of traffic signal devices within a preset device range.

[0064] The preset device range can be set according to the actual situation. For example, the preset device range can be traffic signal devices 40 within a preset distance from the roadside device 20. There may be one or more traffic signal devices 40 within the preset device range. The device information includes the display status of the traffic lights, the number of seconds of prohibited passage, and the number of seconds of passable, etc. For example, the display status is red, green, or yellow. In one example, the device information includes red, and the number of seconds of prohibited passage is ns.

[0065] Step S502: Respond to the appearance of a receiving terminal within the communication range.

[0066] Step S503: Send device information to the receiving terminal.

[0067] Please refer to Figure 3 , in an application scenario, the preset device range of the roadside device 20 includes section E and section F, and the traffic signal device 40 is located between section E and section F and belongs to the preset device range. When the vehicle 30 appears within the communication range of the roadside device 20, the roadside device 20 sends device information to the vehicle 30 so that the vehicle 30 reminds the number of seconds ns for the red light and no passage, and then the user can understand the device information.

[0068] It can be understood that the roadside device 20 can also send the device information of the traffic signal device 40 to the receiving terminal 30 so that the receiving terminal 30 reminds the device information, and then the user can timely understand the device information of the traffic signal device 40 and make timely advance planning.

[0069] This application also provides a method for reminding traffic information. The reminding method is applied to the traffic system 100. Specifically, it is applied to the receiving terminal 30. Please refer to Figure 4 , the reminding method includes step S601: Receive the traffic information sent by the roadside device and remind the user of the traffic information. There are various ways for the receiving terminal 30 to remind the user. For example, the receiving terminal 30 displays and / or broadcasts the traffic information to remind the user.

[0070] In one implementation, receive the road condition information sent by the roadside device 20 and remind the user of the road condition information.

[0071] Please refer to again Figure 3 , in an application scenario, when the vehicle 30 drives into the communicable range of the roadside device 20, the roadside device 20 sends road condition information to the display terminal of the vehicle 30, and the display terminal displays the road condition information and broadcasts the road condition information: "Two vehicles collided on section D ahead. It is expected to take m hours until the traffic accident is handled. It takes K hours to drive from section F to section D. The maximum speed limit on section D and section F is b m / s, and the minimum speed limit is c m / s. Do not speed."

[0072] In an application scenario, when the user holds the electronic device 30 and enters the communicable range of the roadside device 20, the roadside device 20 sends road condition information to the electronic device 30, and the display screen of the electronic device 30 displays the road condition information and broadcasts the road condition information: "Two vehicles collided on section D ahead. It is expected to take m hours until the traffic accident is handled, and it takes G hours to drive to section D.

[0073] In an application scenario, vehicle 30 drives into the communicable range of roadside device 20. The roadside device 20 sends road condition information to the display terminal of vehicle 30. The display terminal displays the road condition information and broadcasts the road condition information: "There are red light running and speed measurement photo taking within the next Lm. Please drive carefully."

[0074] Another way for the receiving terminal 30 to remind the user is that after the receiving terminal 30 receives the road condition information, when the speed of the receiving terminal 30 is less than or equal to the speed range indicated by the road condition information, the speed is adjusted to within the speed range. The speed range can be from the minimum limit speed to the maximum limit speed, where the speed range does not include the maximum limit speed and the minimum limit speed.

[0075] In an application scenario, vehicle 30 drives into the communicable range of roadside device 20. The roadside device 20 sends road condition information to vehicle 30, triggering the driving assistance system of vehicle 30 to reduce the speed of vehicle 30 below the maximum limit speed.

[0076] In another implementation, the traffic signal device 40 that receives the roadside device 20 sends a reminder to the user about the device signal of the traffic signal device 40.

[0077] Please refer to Figure 3 , in an application scenario, vehicle 30 drives into the communicable range of roadside device 20. The roadside device 20 sends device information to the display terminal of vehicle 30. The display terminal displays the device signal and broadcasts the device signal: "There is a traffic light at the intersection ahead. Please drive carefully."

[0078] Another way for the receiving terminal 30 to remind the user is that after the receiving terminal 30 receives the device information, the receiving terminal 30 adjusts the speed of the receiving terminal 30 according to the device information.

[0079] In an application scenario, vehicle 30 drives into the communicable range of roadside device 20. The roadside device 20 sends device information to vehicle 30. The device information indicates that the display state of the traffic signal device 40 ahead changes from yellow light to red light, triggering the driving assistance system of vehicle 30 to adjust according to the change of the display state, so that when the traffic signal device 40 displays a red light and vehicle 30 is located at the zebra crossing, vehicle 30 stops moving.

[0080] It can be understood that the receiving terminal 30 adjusts its state according to the device information, which can prevent the receiving terminal 30 from running a red light and reduce the occurrence of safety accidents.

[0081] In some embodiments, reminding the user of traffic information includes the following steps:

[0082] Step S:701: Store the traffic information into the traffic information list.

[0083] The traffic information list is used to store one or more pieces of traffic information. After receiving the traffic information, the receiving terminal 30 can store the traffic information in the traffic information list.

[0084] Step S702: In response to the user's selection operation on the traffic information list, display or announce the selected traffic information.

[0085] In an application scenario, when the vehicle 30 drives into the communicable range of the roadside device 20, the roadside device 20 continuously sends multiple pieces of road condition information to the vehicle 30. The vehicle 30 stores the multiple pieces of road condition information in the traffic information list. When the user clicks on a piece of road condition information in the traffic information list, the display terminal of the vehicle 30 displays the road condition information and announces the road condition information: "Two vehicles collided on section D ahead. It is expected to take m hours for the traffic accident to be handled. It takes K hours to drive from section F to section D. The maximum speed limit on sections D and F is b m / s, and the minimum speed limit is c m / s. Do not speed."

[0086] In an application scenario, when the user holds the electronic device 30 and enters the communicable range of the roadside device 20, the roadside device 20 continuously sends multiple pieces of road condition information to the electronic device 30. The electronic device 30 stores the multiple pieces of traffic information in the traffic information list. When the user clicks on a piece of road condition information in the traffic information list, the display screen of the electronic device 30 displays the detailed road condition information "A car and a truck collided on section D ahead. There are no casualties. Traffic control is being carried out on section D ahead. It is expected to take m hours for the traffic accident to be handled...", and announces the road condition information: "Two vehicles collided on section D ahead. It is expected to take m hours for the traffic accident to be handled. It takes G hours to drive to section D."

[0087] It can be understood that by storing traffic information in the traffic information list and, in response to the user's selection operation on the traffic information list, displaying or announcing the selected traffic information, the user can freely select the traffic conditions they want to know most recently.
