Study On The Planning And Evaluation Of Bus Network In Dalian

Urban transportation is the basis of urban social and economic development to satisfy citizen travelling. In our urban transportation development stage, the urban road traffic is still the most important and the most basic passenger way. The optimization of urban road passenger transportation planning has become one of important issues.In this paper, under the condition of the passenger transportation way competing, establishes a highway passenger line nets bi-level programming model based on sensitivity analysis, and application of heuristic algorithm of highway passenger line network planning.First, summary the passenger line nets planning method research and the characteristics of network planning. Secondly, for the largest passenger system benefits, based on passenger demand, under the condition of competition, establish highway passenger transport passenger line nets bi-level programming model. Among them, the upper model for highway passenger rail network planning, enterprise profit maximization model as target function and the lower model for passenger equilibrium assignment model, the passenger travel cost minimization as objective function. Third, solute line nets bi-level programming model for highway passenger transport based on sensitivity analysis of heuristic algorithm, achieve the line network optimization results. Finally, taking Dalian highway passenger transport for example, get optimized results through computer software, and prove the practical value of highway passenger line nets bi-level programming model, provide the basis for highway passenger line network optimization and passenger fares management.
