Abstract:With the rapid development of urbanization and the increasing traffic volume, the locations of the main and auxiliary road exits and intersecting roads in urban roads have the great impact on the regional traffic organization. Taking the main and auxiliary road exits of the two roads as the actual cases, through the different traffic organization forms and measured data for the qualitative and quantitative analysis, and by using VISSIM simulation model for data analysis, the traffic capacity and traffic efficiency of the main and auxiliary road entrances and exits under the different traffic flow and different traffic organization conditions are comparatively studied, and the traffic organization schemes under the different traffic flows, distances between the exits and intersecting roads are put forward.
