Architecture of Urban Traffic Control at Intersection in Vehicle Infrastructure Integration Environment

Intersection is becoming the bottleneck of the urban road traffic operation. Based on the discussion of the opportunity of developing traffic control at intersections in vehicle infrastructure integration (VII) environment, by using structure analysis method, system architecture prototype of the urban road traffic control at intersection in VII was brought forward. Relative user demand, logical and physical architecture were also established in detail. Moreover, suggestions about the implementation steps of the architecture and relative guarantee and support measures were also given. This study extends to the field of traffic signal control, which will deeply improve the safety and efficiency of the intersection operation in urban area, and will be successful in the future.
