非集计-弹性模型在公交出行需求分析中的应用研究

Study of Disaggregate-elasticity Model for Bus Travel Demand Analysis

在对非集计-弹性模型进行推导的基础上,对济南公交出行需求的票价弹性影响和出行时间弹性影响进行了分析.结果显示,济南公交票价弹性值为-0.234,公交出行时间的弹性值为-0.394.公交出行时间对公交出行需求的弹性要高于公交票价的弹性,说明通过缩短公交出行时间,提高公交服务水平来增加公交出行吸引力将更有效.

Disaggregate-elasticity model is derived in this paper, based on the model, the fare elasticity and the travel time elasticity of Jinan bus travel demand are analyzed. The results show that the bus fare elasticity is -0. 234 and the bus travel time elasticity is -0. 394, which is slightly lower than the re-lated conclusions at home and abroad. Bus travel time elasticity is higher than bus fare elasticity, which shows shortening bus travel time and improving the bus service level, will be more effective for increasing public transportation attraction.
