| Chongqing city across the country as a typical mountainous city,urban area of steep mountain roads,road network layout intensive and narrow city road congestion,ground transportation system has been unable to meet the growing travel needs.In order to improve the city traffic environment,ease travel congestion of city residents,promote the economic development of the city,Chongqing as the center of the city to play the agglomeration and radiation,Chongqing metro line two project is fully operational on June 2005,the two phase of the project is put into operation in July 2006.Based on the operation condition of line two,this paper studies the post evaluation of Chongqing rail transit construction project.Its main purpose is to summarize the analysis of actual cases through the operation period of the project,check whether the expected data and the actual data deviation,the project plan is reasonable and effective,the main benefit index is achieved by qualitative or quantitative evaluation to find out the reason of success or failure,summarize experience and lessons,for the project being evaluated the problems put forward suggestions for improvement,at the same time also improve the level of decision-making and management of future projects put forward reference basis,so as to improve the investment benefits.Four aspects of the content of this paper mainly from the passenger flow forecast,operation safety,economic benefit and sustainable development of the post evaluation analysis,first introduced the method of rail passenger flow forecast,through the comparative analysis of traffic data and forecasting data of 2009 operation of Chongqing light rail line two,the main reason of the deviation,provide the decision basis for future project construction.Secondly,the article introduces the application status of city rail traffic safety evaluation system and a series of working procedures,evaluation contents and methods,focusing on the city rail transit operation safety evaluation,through the AHP weight operation safety system of each subsystem to determine method.Then use the AHP method to evaluate the effect of city rail traffic on the economy and society,and through the analysis of the influence mechanism of land increment along the proposed influence along the land price model,and with the Chongqing light rail line two as an example of empirical analysis.Next,we discuss the influence of the external environment and internal environment on the sustainable development of urban rail transit,and establish the evaluation model of the sustainability of urban rail transit projects.In addition to the above research results,the paper also lists the problems that need to be further studied,which makes the research of this kind of research more targeted. |
