Analysis of the Keep-Right Rule in Traditional System and Evaluation on Alternative Rules in Intelligent Vehicle-Infrastructure Cooperation Systems

摘要

The keep-right rule is widely implemented in traditional traffic systems, but it might not be the optimal one in intelligent vehicle-infrastructure cooperation systems (i-VICS). According to literature reviews, the free rule is more effective in i-VICS, due to its superior mutual information communication. This paper firstly analyzes the reason why keep-right rule is more popular in traditional traffic systems, and then compares the overtaking procedure under the keep-right rule in traditional traffic systems and free rule in i-VICS. Comparison results show that overtaking in i-VICS is more efficient. Furthermore, five improved alternatives considering speed constraints and vehicle types are proposed and simulated through VISSIM. After this, the simulation results are used to evaluate alternative rules in i-VICS through the TOPSIS method. Additional sensitivity analysis shows that rule 5 is more effective in i-VICS.
