Title:

Develop Right-Turn Real-Time Crash Warning System at Arterial Access Considering Driver Behavior

Abstract:

This paper first investigated drivers’ right-turn behaviors from an access road to an arterial highway. A field test was conducted. The vehicle movement of the right-turn action has been divided into three phases: turn-in, keep-steady, and turn-out. Based on the data in the three phases, a regression model for each phase was established. Model results show that: 1) the overall duration of the three phases of the right-turn maneuver increases with the number of cars coming from the left on the main artery; 2) higher number of cars that are influenced by the arterial traffic increases the duration of first two phases, but decrease the last phase duration.; 3) the longer the first two phases last, the shorter the last phase would be; 4) drivers were found to decelerate before turning right when more than two cars were observed coming from the left on the main arterial road. To help drivers to deal with the difficulties of entering the arterial road from the access road, a conflict warning system for right-turning vehicles based on DSRC (Dedicated Short Range Communications) was developed. Field data were collected and warning algorithms were tested with DSRC on-board and roadside equipment. A corresponding improvement in outliers filter was made and showed a reliable performance of the collision warning system.
