Abstract:By reviewing the development history of characteristic traffic in the mountain city of Chongqing, the multiple characteristic traffic tools under the special terrain condition of Chongqing are introduced. It is pointed out that to achieve the goal of "double carbon", it is necessary to build an environment-friendly green transportation system in order to blend the walking with the traditional transportation. The modern technology is used for iteration and upgrade to build a dynamic three-dimensional Chongqing.
