Research on Driver Behavior in Yellow Interval at Signalized Intersections

الملخص EN

Vehicles are often caught in dilemma zone when they approach signalized intersections in yellow interval.

The existence of dilemma zone which is significantly influenced by driver behavior seriously affects the efficiency and safety of intersections.

This paper proposes the driver behavior models in yellow interval by logistic regression and fuzzy decision tree modeling, respectively, based on camera image data.

Vehicle’s speed and distance to stop line are considered in logistic regression model, which also brings in a dummy variable to describe installation of countdown timer display.

Fuzzy decision tree model is generated by FID3 algorithm whose heuristic information is fuzzy information entropy based on membership functions.

This paper concludes that fuzzy decision tree is more accurate to describe driver behavior at signalized intersection than logistic regression model.
