Abstract

To address the problem of efficient and safe passage in bottleneck sections inside motorway tunnels, this paper designs a projected lane change coordinated passage srategy (PCPS) with the help of an cyber-physical system (CPS) concept in a mixed traffic flow pattern consisting of connected and autonomous vehicles (CAVs) and connected human-drive vehicles (CHVs). Taking into account the characteristics of traffic flow inside motorway tunnels, vehicle following rules and lane changing rules are optimised and corresponding evaluation indicators are selected. The model is simulated with SUMO software, and the comparison of traffic flow, emergency braking ratio and average speed is carried out in two states: no passage strategy (NPS) and PCPS strategy. The results demonstrate that the PCPS strategy can effectively improve the efficiency and safety of traffic flow in bottleneck sections inside motorway tunnels.
