Abstract:
To study the effect of lane reduction on driving behavior and its formation mechanism, a virtual road simulation environment was established. Through the driving simulation system and test, the effect and interaction of multiple control variables such as lane width, turning direction, reduction mode and initial position on driving behavior characteristics were studied. The experiment was organized and the driving behavior indexes, including the speed, horizontal position collected by the driving simulator were used, and the standard deviation were calculated. The method of multifactor data interaction analysis was used to extract the experimental data and analyze the single factor and multi factor interaction, so as to make up for the unilateral deviation of single factor analysis results in the previous literature. The results show that the reduction of lane width make a significant decline on vehicle speed, however, the reduction of lane width also has a significant negative effect on driving lateral position. Compared with the reduction of twosided lane, the reduction of onesided lane through widening the road centerline has a significant impact on reducing vehicle lateral offset. The turning direction also has an impact on the lateral offset, which is smaller when turning right than turning left. The direction of turning and the width of lane compression mode also have an interactive effect on the lateral migration, which is easy to shift to the left in the left curve. The dispersion of lane offset value is affected by unilateral or bilateral reduction mode, lane width, interaction between reduction mode and lane width, and interaction between lane width and turning direction. In addition, the initial position of lane reduction and the direction of the curve have no significant effect on the performance of drivers. The mental load theory may provide a more reasonable explanation for the lane reduction effect. The research is helpful to understand the mechanism of driving characteristics on curves and its relationship with multiple factors. It also provides further theoretical basis for engineering measures to control speed and reduce lateral deviation position at curves. 5 tabs, 10 figs, 37 refs.
