摘要：AbstractRecent studies indicate that the optimization design methods for the isolated signalized intersection, which integrate the temporal and spatial resources, can achieve more effective optimal design relatively. This paper presents extension work to further improve the lane-based method from two aspects of integrating temporal and spatial resources. One is adjusting existing constraints to reserve some conflict movements. The other is adding a constraint to reflect the adverse effects caused by the limitation of short lane. The lane markings and signal settings are taken as binary-type control variables to form BMILP formulas solved by Lingo. The East Beijing Rd and Danfeng St intersection in Nanjing, China is taken as an example. Optimization and simulation results indicate that the new method can obtain better operation performance than the lane-based method, and it is able to reflect the practical operational performance of the intersection which is influenced by short lane within limited length.
