Analyzing toll station capacity impacted by Haizhuwan Tunnel's toll collection model

Haizhuwan Tunnel, as the first underwater tunnel constructed with super large shield technology in Guangzhou area, has important research value on the impact of its toll mode on the characteristics of traffic flow. This study discusses the toll station capacity of Haizhuwan Tunnel under different toll modes, and focuses on analyzing the toll station capacity based on the traffic flow characteristics under different toll modes. The results show that the combination of simple "one vehicle, one bar" and free flow toll has significant advantages in improving traffic efficiency and reducing congestion. Compared with the scheme of setting toll stations, the scheme of setting toll stations has higher safety and lower cost, and the scheme of free flow toll increases the traffic cost of defaulting users, and the road traffic efficiency is also improved.
