Optimization and Control Method of Variable Lanes at Intersection Guided by Colored Asphalt
Considering the variations in traffic flow at urban intersections during different time periods,variable lanes are an essential means to improve intersection efficiency.Addressing the optimization and application issues of variable lanes at intersections,a method for optimizing and controlling vari-able lanes at intersections guided by colored asphalt is proposed.Firstly,based on the integrated princi-ple of lane allocation,signal phase and timing,optimal settings method for variable lanes to enhance the rationality of variable lanes setup and control were proposed.Secondly,the use of colored asphalt materials suitable for variable lanes paving and develop guidance design to enhance the effectiveness of variable lanes applications were investigated.Then,an optimization design and control plan for vari-able lanes using a real intersection as an example was also provided.Finally,we validated the effective-ness of the proposed approach using VISSIM simulation software.The simulation results demonstrate that the optimization and control method for variable lanes can significantly improve intersection effi-ciency.
