Embodiment Construction
[0070] The present invention will be further described below in conjunction with the accompanying drawings.
[0071] The technical problem that this embodiment mainly solves is:
[0072] 1. Analyze the types of traffic conflicts based on the collected traffic conflict data, and obtain three main scenarios: the intersection conflict between the lane-changing vehicle and the following vehicle, the rear-end collision between the lane-changing vehicle and the following vehicle after the lane-changing vehicle completes, and the lane-changing vehicle Intersection conflict with the vehicle in front;
[0073] 2. Use the driving simulator to establish the traffic conflict scene in the highway ramp area, which can collect the driver's reaction time and emergency braking deceleration data, and further establish the driver's reaction time and emergency braking deceleration in different scenarios probability density distribution;
[0074] 3. For each simulated conflict, the corresponding...
