Influence of Bus Route on Two-Lane Traffic Flow

In this paper,a two-lane system with bus route is studied by a cellular automata model.The evolution characteristics and the operational efficiency are analyzed by plotting the fundamental diagram and the vehicle occupancy on the right lane(nearside lane).The two types of bus stops,namely,non-harbor shaped and harbor shaped,are considered,and the merits of the two types of bus stop are compared.The simulation results show that there are four density regions with different evolution dynamics of traffic flow;The maximum flow is decreased with the number of buses increasing.The bus route with harbor-shaped stop exerts less affects to the traffic flow and its maximum flow is higher than the bus route with non-harbor-shaped stop.
