The Research Of Interactive Relation Between City Land-use And Urban Transportation

City modernization develops more and more quickly, science and technology changesrapidly, the new technology of motor vehicles also emerges in an endless stream. Theaccommodation of traffic facilities is difficult to satisfy the traffic demandgrowth, the urban transportation problem is becoming more and more serious because ofthe imbalance between supply and demand. So the traffic problem has become themost urgent in our country and even the world’s. Land-use is the "source" of trafficdemand, it determines the distribution from the flow of people and goods in space; thetransportation system affects the pattern of land-use conversely in the city;land-use and urban transportation affect and feedback each other. The land resources arelimited, and it’s unlimited to development, the core of solving the urban transportationproblem is to plan the city land-use and transportation together, to realize coordinateddevelopment between them, and eventually realize the city’s long-term development, inorder to provide scientific basis for the city spatial structure optimization design, andeventually realize the city for long-term development.This paper carried out the relationship between the city land-use and urbantransportation, through analyzed the development and utilization mode of the both andarranged the research and development process in our country, meanwhile, researched thesymbiosis mechanism when make the plan to them, thus, to reveal the internal law of theboth, that is city land-use makes the “resource” of traffic demand, the situation of cityland-use was influenced from the level of traffic development. Through analyzed thepresent situation, characteristic and trouble, the author put forward that to solve the urbantransportation problem do not rely on improve the maneuverability and expand the trafficsupply simply, the two coordinated development was the fundamental idea of citysustainable development.This paper combined the high density spatial development features of our country, took the six urban districts in Beijing（2011）as an example, Analyzed the present situationof land-use and transportation, selected the evaluation indexes which influenced therelationship between them, surveyed and collected abundant data which was interrelatedthem, then calculated, arranged and analyzed every evaluation indexes. To take AHP toconstructed a coordination degree evaluation index system between urban transportationand city land-use, adopted the methods of expert investigating(Delphy) to give weight forthat evaluation indexes in coordination degree evaluation index system, and surveyed thestandard value, then weighted processing and gave the comprehensive evaluation to thedegree of coordination on the basis of the grading standards. Finally, obtained the degree ofcoordination with land-use and transportation in the six urban districts of Beijing（2011）according to the result and rating scale of the index degree of coordination, the result isnormal coordination. The conclusion provides the theoretical basis for the coordinateddevelopment and sustainable development between city land-use and urban transportation.
