In order to alleviate the low efficiency utilization of public transportation resources in the urban traffic of our country, the paper is put forward to analyze the planning methods of integrated passenger transit network, which gives an emphasis on the efficient cohesion, coordination and transfer between different modes of transportation, as well as gives a consideration to the urban development planning and the program of land layout. With a large number of data and field investigation, the paper found that we should give full consideration to the related indicators and set a goal function, then match each O-D point to choose the appropriate sections and appropriate means of transportation, and thus establish the model of a bi-level programming and the corresponding bi-level iterative algorithm in the urban passenger transit network planning of integration. Finally the model will be applied to the city’s passenger transport, and the various indexes before and after the project will be compared in order to test whether model established is correct or not.

In order to alleviate the low efficiency utilization of public transportation resources in the urban traffic of our country, the paper is put forward to analyze the planning methods of integrated passenger transit network, which gives an emphasis on the efficient cohesion, coordination and transfer between different modes of transportation, as well as gives a consideration to the urban development planning and the program of land layout. With a large number of data and field investigation, the paper found, based on the site and hinge layout planning provided the O-D points of the route, we should give full consideration to the constraint conditions and set goal functions, then match each O-D point and choose the appropriate sections and appropriate means of transportation, when we do the planning of integrated urban passenger transit network. Meanwhile this paper established the model of a bi-level programming and the corresponding bi-level iterative algorithm. Finally the model will be applied to the passenger transport of Hohhot , and the various indexes before and after the project will be compared in order to test whether the model established is correct or not.

The road traffic problem is growing worse and worse, its roots in the imbalance of road transport supply and demand. This article analysis the characteristics of traffic supply, traffic demand and supply-demand balance to make sure that the interval of supply-demand balance is exist, meanwhile make the total length of road net as a parameter then work with the level of service of the road net to built a interval model to work out the interval, then get the internal development law of supply-demand balance by the combination of qualitative and quantitative. After get the law, people can use it to optimizing the limit traffic resource of city, consummating the knowledge frame of transportation planning, at last to remitting traffic congestion and making it convenient for people to travel.
