Description

Technical Field

[0001] This disclosure relates to the field of traffic safety technology, specifically to a traffic incident data acquisition method, a traffic incident data acquisition system, an electronic device, and a computer-readable storage medium. Background Technology

[0002] Mixed traffic is the current state of traffic, especially the mixing of motor vehicles and non-motor vehicles. In mixed traffic, motor vehicles and non-motor vehicles often conflict and interfere with each other, leading to reduced traffic efficiency and safety, and increasing the risk of accidents. Non-motorized vehicles, especially pedestrians, are often referred to as "vulnerable road users."

[0003] For a long time, transportation systems have typically been built around motor vehicles, including the determination of traffic accidents. For example, current vehicles are equipped with Event Data Recorders (EDRs) to record key operational data of the vehicle in three phases: before, during, and after a collision. This data includes speed, ABS status, steering wheel angle, airbag status, and vehicle braking status, reconstructing the situation before and after the accident from the vehicle's operational perspective. Specifically, the EDR is in a "sleep state" during normal, stable driving, only being activated when there is a sudden, drastic change in speed, instantly recording and storing important vehicle operational data.

[0004] Vehicle EDR requires certain triggering conditions. When a vulnerable road user faces a powerful road user with significantly different strength, and a contact-type traffic incident occurs, if the powerful party does not meet the triggering or locking conditions, the event data cannot be accurately recorded or locked. Furthermore, if the vulnerable party is a non-motorized vehicle, it may be impossible to obtain traffic event information at the time of the incident. Summary of the Invention

[0062] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments and drawings described herein are merely for explaining the invention and are not intended to limit the invention.

[0066] The following detailed embodiments illustrate the technical solutions of this disclosure and how they solve the aforementioned technical problems in the prior art. It is understood that in the embodiments of this application, the executing entity may perform some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application may also perform other operations or variations thereof. Furthermore, the steps may be executed in different orders as presented in the embodiments of this application, and it is not necessary to execute all the operations in the embodiments of this application. Moreover, the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0067] Figure 1 This is a flowchart illustrating a traffic incident data collection method provided in Embodiment 1 of this disclosure, applied to a user's traffic incident recording device, such as... Figure 1 As shown, the method includes:

[0068] Step S101: Continuously monitor user status;

[0069] The user traffic incident recording device is a traffic incident recording device for vulnerable traffic participants. For example, when a user is walking, it can be a pedestrian traffic incident recording device, and when a user is cycling, it can be a cyclist traffic incident recording device. The user traffic incident recording device is carried by the user and can be handheld or set as a wearable electronic device. It is used to continuously monitor the user's status and has two data recording states: one is to record and store relevant information before and after the event when the trigger condition is met, and the other is to store, mark and forcibly report the event information to the traffic incident management platform when the lock condition is met.

[0070] Furthermore, the user state includes the user's motion state;

[0071] The user's motion status includes the user's speed, cadence, stride length, and motion posture.

[0072] User status includes user movement status. Taking walking as an example, user traffic event recording devices continuously monitor users' speed, cadence, stride length, and movement posture. Under normal circumstances, users' movement status is relatively stable, and their speed, cadence, stride length, and movement posture do not change drastically. User traffic event recording devices determine whether a traffic event has occurred by monitoring users' movement status.

[0073] Furthermore, the user status also includes location information and vital signs;

[0074] The vital signs include the user's heart rate, pulse, blood pressure, and blood oxygen.

[0075] User status can be measured using existing handheld terminals and wearable devices, such as combining the positioning functions of sports watches and mobile terminals. While monitoring user status, the system can also monitor the user's location information and vital signs, and determine whether the user has triggered a traffic incident based on the user's vital signs.

[0076] Furthermore, the method also includes:

[0077] The monitored user status data is associated with user identity information, which includes one or more of the following:

[0078] ID card information, mobile phone number, and unique terminal device code.

[0079] By associating user status data with user identity information to identify the user, the collected data is linked to user identity information, enabling subsequent data to be associated with people and vehicles.

[0080] Step S102: In response to the user's state reaching the preset traffic event triggering condition, record and store the user's state information within a preset time range before and after the traffic event occurs;

[0081] When a user's state changes to the preset trigger condition, the device will start recording user state information for a period of time before, during, and after the event and store it in the device. For example, if the user stops suddenly or brakes suddenly while riding, if the user is not injured or only slightly injured, or if the change is not very intense, only the relevant information before and after the event will be recorded and stored. The trigger condition can be one or more of the following indicators that reach the set value within a certain time range: change value of speed, intensity of vibration, vital sign threshold, etc.

[0082] Step S103: Further determine whether the user's status meets the preset locking conditions;

[0083] After a user's status reaches the preset traffic event triggering conditions, it is further determined whether the preset locking conditions have been met. The locking conditions are indicators that further define the severity of the event based on the triggering conditions. For example, if the user's speed changes drastically or the user's vital signs exceed the normal range by a large margin, it may indicate that the user has triggered a collision. If the locking conditions are met at this time, more traffic event information needs to be collected.

[0084] Furthermore,

[0085] The user's state reaching the preset traffic event triggering conditions includes:

[0086] If the rate of change of parameters in the user's motion state exceeds the first preset value, or if one or more of the vital signs indicators reach the set first threshold within a certain time range;

[0087] The preset locking conditions include:

[0088] If the rate of change of parameters in the user's motion state exceeds the second preset value, or if one or more of the vital signs indicators reach the set second threshold within a certain time range;

[0089] Among them, the second preset value is greater than the first preset value, and both the second threshold and the first threshold exceed the normal range of vital signs indicators, with the second threshold exceeding the limit by more.

[0090] The first and second preset values ​​can be set according to the user's travel mode or traffic conditions. They can be set according to the actual situation. If the first preset value is exceeded, it indicates that the user's status has changed, such as avoiding obstacles. The first and second thresholds can be set according to the user's vital signs under normal conditions. The first threshold can be slightly exceeded, such as when the heart rate increases due to stimulation. The second threshold can be set when the user is injured, such as when the heart rate exceeds the normal range by a large margin or when the blood pressure drops. They can be set according to the actual situation and experience.

[0091] Step S104: If yes, then lock the traffic incident and the corresponding traffic incident data and report them to the traffic incident management platform; and,

[0092] If the preset locking conditions are met, it indicates that the traffic incident is serious or that a collision has occurred. In this case, it is necessary to lock the triggered event and the corresponding data and report it to the traffic incident management platform to prevent the data from being overwritten, so that the handling department can know the user status and provide a basis for subsequent liability determination.

[0093] Step S105: Notify the roadside event recording equipment under its jurisdiction and vehicles within a certain range to simultaneously record the current traffic status information.

[0094] The vehicle is equipped with a vehicle event recording device, which can collect the vehicle's own driving information and surrounding traffic conditions. The roadside event recording device can record the traffic conditions when an event is triggered through multiple sensors such as cameras. When preset locking conditions are met, the device notifies the roadside event recording devices under its jurisdiction and vehicles within a certain range to simultaneously record the current traffic status information; this achieves the collection of data on vehicles, traffic participants, and the external traffic environment from three perspectives: people, vehicles, and roads, to better record traffic event information.

[0095] Furthermore, the method also includes:

[0096] After notifying the roadside event recording devices and vehicles within a certain range to synchronously record the current traffic status information, the roadside event recording devices and vehicles within the certain range upload the recorded current traffic status information to the traffic event management platform.

[0097] By aggregating all data into the traffic incident management platform, incident data can be better correlated, and relevant departments can more easily handle incidents.

[0098] Furthermore, the current traffic status information includes:

[0099] Driving data, external environmental information collected by the activated sensors, and identification information of surrounding vehicles;

[0100] The sensing devices include cameras, radar, positioning devices, weather condition acquisition devices, and road condition acquisition devices.

[0101] The vehicle identification information includes at least one of the following: license plate number, engine number, and vehicle identification number.

[0102] When a preset trigger condition is met, the vehicle event recording device will start recording driving status data within a certain period before, during, and after the event, including but not limited to driving operation data, images, videos, and other information. All collected data will be timestamped and associated with vehicle identity information, including but not limited to license plate number, engine number, and chassis number. If a preset locking condition is met and a notification is received from the user's traffic event recording device, the device will lock the traffic status information within a certain time range, including but not limited to driving data, and activate sensors such as cameras, radar, positioning, weather, and road surface sensors to collect information about the external environment of the event and the identity information of surrounding vehicles.

[0103] Roadside event recording devices can be located in electronic equipment of road traffic infrastructure. Their main function is to record traffic status data within their coverage area after receiving a lock event notification sent by the user's traffic event recording device. This includes, but is not limited to, activating sensing devices such as cameras, radar, positioning, weather, and road surface devices to collect information about the external environment of the event and the identity information of surrounding vehicles; and storing and managing the data.

[0104] Furthermore, the method also includes:

[0105] Traffic accident alarms and / or medical emergency alarms can be sent via voice or button on the user's traffic event recording device; or...

[0106] Traffic accident alarms and / or medical emergency alarms are automatically sent based on vital sign data parameters that characterize the severity of the incident.

[0107] In the event of a serious traffic incident, if the preset locking conditions are met, the device can automatically send traffic accident alarms and / or medical emergency alarms through its capabilities, such as voice or button input. Alternatively, it can automatically send traffic accident alarms and / or medical emergency alarms when the user's vital signs data parameters are abnormal, enabling the incident to be handled and treated as quickly as possible.

[0108] Furthermore, the method also includes:

[0109] After notifying the roadside event recording devices under its jurisdiction and vehicles within a certain range to synchronously record the current traffic status information, the roadside event recording devices communicate with the user traffic event recording devices and vehicle event recording devices within the coverage area to aggregate the data generated by traffic events within their coverage area, and complete the association between the traffic event data and traffic status information through the time and vehicle identity information of the data.

[0110] Roadside event recording devices communicate with user and vehicle event recording devices within their coverage area to aggregate traffic event data within that area. By using the time of the data and vehicle identification tags, they correlate traffic data collected from three perspectives—people, vehicles, and roads—to better handle traffic events.

[0111] This disclosure defines the identity data of vulnerable traffic participants from the perspective of data collection, and triggers the data collection of traffic events from the perspective of vulnerable traffic participants; by collecting data on vehicles, traffic participants, and the external traffic environment from the three perspectives of people, vehicles, and roads, it can better realize the data collection of traffic events.

[0112] Figure 2 This is a flowchart illustrating a traffic incident data collection method provided in Embodiment 2 of this disclosure, applied to a traffic incident management platform, such as... Figure 3 As shown, the method includes:

[0113] Step S201: Receive traffic events and traffic event data reported by the user's traffic event recording device. The traffic event data is continuously monitored by the user's traffic event recording device. In response to the user's status reaching the preset traffic event triggering conditions, the device records and stores the user's status information within a preset time range before and after the event. When the user's status reaches the preset locking conditions, the device locks the traffic event and the corresponding traffic event data and reports it. Furthermore, when the user's status reaches the preset locking conditions, the user's traffic event recording device notifies the roadside event recording devices under its jurisdiction and vehicles within a certain range to synchronously record the current traffic status information.

[0114] The traffic incident management platform can be operated by relevant traffic management departments. It can receive traffic incidents and traffic incident data reported by users' traffic incident recording devices, obtain information collected from vulnerable parties during traffic incidents, and record incident information from multiple angles from roadside incident recording devices and vehicles within a certain range after the user's traffic incident recording device notifies the roadside incident recording devices and vehicles under its jurisdiction to record the current traffic status information simultaneously.

[0115] Furthermore, the method also includes:

[0116] It receives current traffic status information reported by roadside event recording devices under the jurisdiction of the user's traffic event recording device and vehicles within a certain range;

[0117] It aggregates the current traffic status information and traffic event data, and associates, stores, and manages the data with the identities of vehicles and users.

[0118] The traffic incident management platform aggregates traffic data recorded by vehicle incident recording devices (vehicle and user traffic incident recording devices) and roadside incident recording devices, and associates, stores, and manages the incident data with the identities of vehicles and personnel; it facilitates relevant departments to identify traffic incidents, determine key incident information, and complete the determination of traffic accidents.

[0119] Furthermore, the method also includes:

[0120] Based on the diagnostic results of the traffic incident, the roadside event recording device is notified to lock the current traffic status information, and the roadside event recording device also notifies the user's traffic event recording device to lock the current traffic status information of vehicles within a certain range.

[0121] After external diagnosis of a traffic incident, it is determined whether the data needs to be locked. If so, the data is locked, and the roadside event recording device is notified to lock the current traffic status information. At the same time, the vehicle is notified to lock the data, or the roadside event recording device is notified to the vehicle to lock the data. This ensures that the original data is not overwritten, which facilitates subsequent incident processing.

[0122] The traffic incident management platform allows users to view incidents and related traffic data across the entire area, including time intervals, geographical location intervals, and records of related vehicles involved in the incident. Similarly, the roadside incident recording device allows users to view incidents and related traffic data within its coverage area, including time intervals, geographical location intervals, records of related vehicles involved in the incident, and complete traffic incident record data sources and recording perspectives.

[0123] Furthermore, in the traffic incident collection system, the vehicle incident recording devices (including user traffic incident recording devices and vehicle incident recording devices) and the roadside incident recording devices can interact via communication links, including but not limited to mobile cellular communication technologies such as 2G / 3G / 4G / 5G Uu interfaces, direct communication technologies such as LTE-V2X, 5G-V2X, DSRC PC5 interfaces, and satellite communication technologies; the roadside incident recording devices and the traffic incident management platform can interact via one or more communication links.

[0124] This disclosure embodiment manages data from three sources in a way that links them together, using an event dimension and spatiotemporal context as clues. It triggers event data collection from the vulnerable party in traffic and obtains on-site data from multiple perspectives to ensure comprehensive data collection and better achieve traffic event data collection.

[0125] To more clearly describe the technical solution disclosed herein, such as Figure 3 and Figure 4 As shown, Embodiment 3 of this disclosure also provides a method for collecting traffic incident data; this embodiment is based on... Figure 3 The traffic incident data collection and processing system shown realizes traffic incident data collection. The vehicle incident recording device includes a pedestrian incident recording device (i.e., the aforementioned user traffic incident recording device applied to pedestrians) and a vehicle incident recording device, which are used to collect and record pedestrian status and vehicle data, respectively. The vehicle incident recording device has two data recording states: one is to record and store relevant information before and after the event when the trigger condition is met; the other is to store, mark and forcibly report the event information to the traffic incident management platform when the lock condition is met.

[0126] The pedestrian event recording device, located on the pedestrian's handheld or wearable electronic device, primarily functions to continuously monitor the pedestrian's status, including but not limited to walking status (such as speed, cadence, stride length, and posture), location information, and vital signs (such as heart rate, pulse, blood pressure, and blood oxygen). When a preset trigger condition is met, it will initiate the recording of pedestrian status information for a period before, during, and after the event, including but not limited to walking status (such as speed, cadence, stride length, and posture), location information, and vital signs (such as heart rate, pulse, blood pressure, and blood oxygen). All collected data is associated with the pedestrian's identity information, including but not limited to ID card information. Information such as mobile phone number and unique terminal device code; furthermore, if the preset locking conditions are met, the roadside event recording equipment and surrounding vehicles are notified to simultaneously record the current traffic status information, including but not limited to driving data, activating sensing devices such as cameras, radar, positioning, weather, road surface, etc. to collect external environmental information of the event and the identity information of surrounding vehicles, including but not limited to license plate number, engine number, vehicle frame number and other unique identification information; further still, depending on the capabilities of the pedestrian event recording equipment, traffic accident alarms and / or medical emergency alarms are sent manually or automatically through voice, button and human vital sign data parameters that characterize the severity of the event;

[0127] The preset triggering conditions of the pedestrian device include, but are not limited to, one or more of the following indicators: speed change value within a certain time range, intensity of vibration, vital sign threshold, etc.; the locking condition is an indicator that further defines the severity of the event based on the triggering conditions, which assists the device in locking the triggered event and the corresponding data and reporting it to the traffic event management platform.

[0128] The vehicle event recording device, located inside the vehicle module, primarily functions to record driving status data for a period of time before, during, and after an event when a preset trigger condition is met. This data includes, but is not limited to, driving operation data, images, and videos. All collected data is timestamped and associated with vehicle identity information, including, but not limited to, license plate number, engine number, and chassis number. Furthermore, if a preset locking condition is met, the device locks traffic status information for a certain time period, including, but not limited to, driving data, and activates sensors such as cameras, radar, positioning, weather, and road surface sensors to collect external environmental information and the identity information of surrounding vehicles.

[0129] The preset triggering conditions of the vehicle equipment include, but are not limited to, indicators such as the change values ​​of lateral and longitudinal speeds within a certain time range, the intensity of vibration, and the state changes of irreversible restraint devices; the locking conditions, on the one hand, further define the indicators of the severity of the event based on the triggering conditions, and on the other hand, trigger the locking by notifying the surrounding area to record the current traffic status after the pedestrian event recording device issues a locking event, and assist the device in locking the event and the corresponding data.

[0130] The roadside event recording device can be located in the electronic equipment of road traffic infrastructure. Its main function is to record traffic status data within its coverage area after receiving a locking event notification sent by a pedestrian device. This includes, but is not limited to, activating sensing devices such as cameras, radar, positioning, weather, and road surface devices to collect information on the external environment of the event and the identity information of surrounding vehicles; and storing and managing the data.

[0131] Furthermore, the roadside event recording device communicates with vehicle event recording devices within its coverage area to aggregate traffic event data within its coverage area, and associates the traffic data involved in the incident through the time of the data and the vehicle identification tag.

[0132] The traffic incident management platform can be operated by the relevant traffic management department. Its main function is to collect traffic data recorded by the vehicle incident recording device and the roadside incident recording device, and to associate, store and manage the incident data with the identity of the vehicle and the person.

[0133] The traffic incident management platform allows users to view incidents and related traffic data across the entire area, including time intervals, geographical location intervals, and records of related vehicles involved in the incident; the roadside incident recording device also allows users to view incidents and related traffic data within its coverage area, including time intervals, geographical location intervals, records of related vehicles involved in the incident, complete traffic incident recording data sources and recording perspectives;

[0134] Furthermore, the traffic incident management platform can notify the roadside incident recording device whether to lock the traffic incident based on external diagnostic results; the roadside incident recording device can notify the incident recording device of the vehicle involved to lock the incident data based on external data diagnostic results.

[0135] In the traffic incident collection system, the vehicle incident recording device and the roadside incident recording device can exchange information via communication links, including but not limited to mobile cellular communication technologies such as 2G / 3G / 4G / 5G Uu interfaces, direct communication technologies such as LTE-V2X, 5G-V2X, DSRC PC5 interfaces, and satellite communication technologies; the roadside incident recording device and the traffic incident management platform can exchange information via one or more communication links.
