Control Type Styles Option Research of Intersection Based on LOS

The intersection is the critical node in city, and has important influence on traffic flow. Whether the intersection is controlled reasonably is the key to the safety and efficiency of the intersection. Because of the current urban intersection control type existing unreasonably, In view of this situation, typical intersection is selected as main object of study. LOS is chosen as Performance Index, 8160 simulation tests of different levels of demand are designed by using Traffic simulation software, four scenarios with 5%, 10%, 15%, and 20% of the different volumes are assigned to make left turns. Each test is made respectively with signalized intersection, unsignalized intersection and roundabout. The Choose figures are given as the base of the intersection control types and comprehensive benefits for intersection analysis.
