Study on Corner Clearance of Signalized Intersection of Beijing
Currently, the study on access design has not yet conducted widely in large cities such as Beijing. As a result, there is no specification or criterion to dictate the layout and design of driveways connecting to roadways. Generally, these driveways are closely located to the signalized intersection. The egress and ingress of vehicles will greatly impact the operation of traffic at the intersection. In addition, this type of design brings about serious safety problems. The objective of this study is to determine the minimum spacing between access and signalized intersection of Beijing based on corner clearance technology. As is known, corner clearance technology is one of the access management strategy. By analyzing the constraints on the corner clearance of the intersection, the influencing factors are determined. On this basis, a minimum spacing model between the access and the intersection is established in the paper. In order to analyze the influencing factors on corner clearance of urban major roadways, the simulation model is used. The delay is regarded as an evaluation index. The simulation-based minimum corner clearance is determined. The result of this study can help traffic engineers to make sensible decision on the layout and design of accesses near the signalized intersections of Beijing.
