ABSTRACT
The variable speed limit is vital in improving the traffic condition under incidents. Since the lack of funds to install many detectors, existing variable speed limit control algorithms are difficult to apply to remote freeways. A variable speed limit control model is proposed in this paper to solve the problem of variable speed limits on remote freeways. The model describes the parameter setting of variable speed limit control. In the experiment, a two-way four-lane highway model is built in VISSIM. The traffic volume at different levels of service is selected as the vehicle input. The maximum queue length is chosen as the index to evaluate traffic efficiency under different control strategies. The results show that our proposed model can reduce the queue length by 38.77% at most under traffic volume at the second level of service.
