Analysis Of Urban Bus Riding Behavior And Equilibrium Model In Peak Period

In the worldwide,almost all major cities endure long travel time,public transport overcrowded, congested roads and environmental pollution. At present, the good public transport system is generally regarded as an important cornerstone of sustainable urban development. How to ensure the efficient and convenient transportation system on the basis of low price has always been an important subject in the field of transportation.Firstly, this paper introduced an equilibrium model of a one-to-one transit system in rush hours based on bottleneck model. Commuters are assumed to choose their optimal time-of-use decision by trading off crowding cost against the schedule delay cost and no commuter can reduce his/her total commuting cost by unilaterally changing his/her departure time or train service in equilibrium state.In previous studies, it is often assumed that all bus vehicles at peak periods are fully loaded. This paper added capacity constraints into the original equilibrium model to take the impact of seats into consideration. The equivalent minimization problem considering those constraints is established and the first-order optimality condition is derived. We demonstrate that the saturation period of the bus is continuous during the peak period. Subsequently, an example is given to demonstrate the feasibility of reducing the cost of travel by adjusting the number of seats.Finally,in order to study the waiting behavior and travel choice of travelers at the bus station, this paper established a bus travel network with waiting arcs and constructed the user equilibrium model under the random service rule. The results show that the traveler's choice of departure time does not produce waiting flow. Then, this paper introduced the analysis framework of prospect theory and defined the reference point of traveler waiting behavior and ride choice. This paper analyzed the difference of traffic distribution under the condition of prospect theory and expectation theory, and the focus is on the flow change of waiting arc.
