Predicting Driver Behavior Using Field Experiment Data and Driving Simulator Experiment Data : Assessing Impact of Elimination of Stop Regulation at Railway Crossings

الملخص EN

We investigated the impact of deregulating the presence of stop signs at railway crossings on car driver behavior.

We estimated the probability that a driver would stop inside the crossing, thereby obstructing the tracks, when a lead vehicle suddenly stopped after the crossing and a stop regulation was eliminated.

We proposed a new assessment method of the driving behavior as follows: first, collecting driving behavior data in a driving simulator and in a real road environment; then, predicting the probability based on the collected data.

In the simulator experiment, we measured the distances between a lead vehicle and the driver’s vehicle and the driver’s response time to the deceleration of the leading vehicle when entering the railway crossing.

We investigated the influence of the presence of two leading vehicles on the driver’s vehicle movements.

The deceleration data were recorded in the field experiments.

Slower driving speed led to a higher probability of stopping inside the railway crossing.

The probability was higher when the vehicle in front of the leading vehicle did not slow down than when both the lead vehicle and the vehicle in front of it slowed down.

Finally, advantages of our new assessment method were discussed.
