Research on Dynamic Merge Control at Freeway Expanding Reconstruction SectionAuthor/Presenter: Kong, Dewen; Guo, Xiucheng; Hou, Jia
In order to improve the safety and efficiency of the freeway expanding construction work zone, aiming at the merging traffic before the section, by studying the existing measures to control the merging traffic at home and abroad, this paper analyzes the respective advantages and disadvantages of each situation and condition. It proposes a dynamic vehicle merging system that has a wider application range and adapts to the real-time traffic and then works out the process of system operation and threshold model. Finally, a simulation by VISSIM will identify the correctness and practicability of our model. The result shows that, in comparison with the conventional control of merging traffic, the improved system has a distinct advantage in efficiency.
