By means of field surveyon urban road intersections, the vehicle type composition proportions were analyzed, and the small vehicles were taken as the standard vehicle type.
Therefore based on the characteristic analysis of 686 vehicle accesses from 198 TIA projects in Beijing, 44 survey locations were chosen as the typical study objects for this research.
