V2X Hit-and-Run Tracking via DSRC Cascade Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hit and run incidents often go unpunished due to the inability to identify perpetrators in time, as victims cannot obtain the driver's information before they flee the scene, especially in urban areas where vehicles are frequently parked on streets.
Innovation Solution
Implementing a V2X communication system using the DSRC protocol, where a host vehicle detects a collision and broadcasts a tracking message with the target vehicle's identifying information and a cascade duration, allowing bystander vehicles and roadside units to track and rebroadcast this information to compile data for authorities.

Engineering Contradiction Analysis
1Measurement precision
If V2X communication system is implemented to track hit and run perpetrators, then the ability to identify perpetrators is improved, but the device complexity increases
Solution Approach 1:
The tracking system is segmented into multiple independent components: collision detection module, message generation module, message reception module, and tracking information compilation module. Each component performs a specific function, reducing overall system complexity while maintaining identification accuracy through coordinated operation of these modular elements.
Solution Approach 2:
The V2X communication system is designed to serve multiple functions: normal vehicle communication, collision detection, hit-and-run tracking, and perpetrator identification. By making the communication infrastructure universal and multi-functional, the system avoids requiring separate dedicated systems for each function, thereby reducing device complexity while improving identification capability.
2Area of stationary object
If tracking messages are broadcast through multiple vehicles and roadside units, then the tracking coverage is improved, but the loss of time increases due to message propagation delays
Solution Approach 1:
The system performs preliminary actions by pre-establishing the V2X communication network and having all vehicles and roadside units ready to receive and forward tracking messages. When a hit-and-run event occurs, the message can be immediately propagated through the pre-configured network, reducing propagation delay while achieving wide coverage through the existing infrastructure.
Solution Approach 2:
The tracking message is copied and rebroadcast by multiple vehicles and roadside units simultaneously as they receive it. This copying mechanism allows the message to propagate rapidly through the network without sequential delays, as each node independently forwards the message to its neighbors, achieving both wide coverage and fast propagation.
3Reliability
If the cascade duration is extended to allow more vehicles to track the perpetrator, then the tracking effectiveness is improved, but the loss of time increases
Solution Approach 1:
The cascade duration implements periodic action by setting a predetermined time limit for message propagation. The message is rebroadcast at regular intervals until the cascade duration expires, ensuring that tracking information reaches multiple vehicles within a controlled time frame. This periodic rebroadcasting maintains tracking effectiveness while preventing excessive time loss through unlimited propagation.

AI summary
Method and apparatus are disclosed for tracking hit and run perpetrators using V2X communication. An example host vehicle includes a first hardware module and a second hardware module. The first hardware module detects a collision with a target vehicle, and determines whether the collision is a hit-and-run event. The second hardware module collects identifying information of the target vehicle, and when the collision is the hit-and-run event, broadcasts a message including the identifying information and a cascade duration.
