Human-Vehicle Intersection Traffic Lights Timing Optimization Research

The purpose of this research is to find a traffic light timing optimization scheme. During the research, an intersection between Xi’an Mingguang road and Fourth FengCheng was chosen analyze crossing time distribution pedestrians who were separated from west-to-the-right-turn vehicles during which method breaking off both ends pedestrian green signals used. VISSIM software used for simulation, aimed at improving volume right-turning vehicle average speed less queuing delays, human-vehicle conflicts, better security without excessive interruption on their street efficiency. optimal scheme obtained result shows that (1) number passing remains unchanged, with delay reduced by 5.78% crosswalk increased 19.01% compared original one. (2) As effect positively correlated increase right turn numbers, could be adopted urban management based local situation, not only in peak hours but also flat ensure efficiency safety “vehicle yielding pedestrians” regulation. (3) cities no policy people-vehicle separation when streets.
