公交补贴与运营策略的实施效果分析

In a linear monocentric city considering the heterogeneity in residents income levels, an equilibrium model for travel mode and residential location choice is constructed, and five possible travel distribution modes are discussed. This paper studies the impacts of public transit subsidy and operation strategies on residents' travel mode split and land rental prices. Moreover, the changes in residents' utility level and government' land rental income are also studied. The results show that under different travel distribution modes, the implementation effects of public transit subsidies and operation strategies are different. When all residents are bus users, these three bus strategies can benefit all residents, but neither narrowing the utility gap nor increasing the government rental income. When some residents drive to work, these three measures can narrow the utility gap among residents and promote social equity. However, under all travel distribution patterns, increasing the average travel speed of a bus will reduce the government' rental income. This research can provide reference and inspiration for the traffic management department to formulate public transit subsidies and operation strategies.
