Abstract: The priority development of urban public transport and innovative optimization of traffic organization and management are effective ways to solve the urban traffic problem. It is effective to improve the traffic capacity of the intersection without changing the original road facility conditions of the intersection by setting comprehensive approach area. Based on the methods of setting the comprehensive approach area and bus priority at intersections, the layout method and setting conditions of comprehensive approach area and bus priority at the entrance of intersection were discussed. And a traffic organization and signal control method at intersections based on bus priority and comprehensive approach area was proposed. And VISSIM micro-simulation software was used to verify an intersection in Nanchang. The research results show that: compared with the condition before optimization, setting the comprehensive approach area based on bus priority at the entrance of intersection reduces the average delay of social vehicles and significantly reduces the average delay of public transport at the same time.
