新建高速公路诱增交通量与区域经济互动关系——以贵州省为例

Interrelationships Between Induced Traffic Volume of New Highway and Regional Economy: A Case Study of Guizhou Province

新建高速公路的诱增交通量与项目区域经济的互动关系在计算诱增交通量时无法体现,本文对常规重力模型进行适当调整,使其表现由新建交通项目诱增的交通量与项目区域经济的互动性关系。以厦蓉高速的贵州省与广东省段及贵州省内新建高速交通项目为例,实例计算由于新建的交通项目诱增的交通量与经济之间的关系,结果表明的新建高速公路明显缩短两经济区域的时间距离,增大了贵州省内的地级市连通度,从而诱增部分交通量并促进两区域经济增长。

It can not be reflected when calculating the traffic volume of the new highway with the interaction of the regional economy. The conventional gravity model was properly adjusted so that it could reflect the interaction of increased new traffic volume and regional economy of the project site. Take the sections in Guangdong and Guizhou along the Xiamen-Chengdu highway and the newly built highways for example to calculate the relations between the induced traffic volume and economy. The results showed that the new highways obviously shortened the time and space of the two economic regions, and increased the connection between prefecture-level cities in Guizhou province, thus increasing traffic volume and promoting growth of religional economy.
