提出了交通方式间竞争关系的理论框架,分析了基于出行时间和基于出行综合成本上的公共交通与自行车及小汽车间的竞争,推导出相应的竞争均衡模型。根据判别模型分析得出各个影响因素与公共交通竞争力间的函数关系,并提出相应的政策措施。 Proposed the theoretical framework of the competitive relationship between modes of transport, and analyzed the competition between public transport and bicycles and cars based on the travel time and the comprehensive travel cost, and derived the corresponding competitive equilibrium model. According to the discriminant model, we get the functional relationship between each influencing factor and the public transport competitiveness and put forward the corresponding policy measures.
