公共交通线路调整影响分析是一个定量与定性相结合、经验与理论相结合、创新与反馈相结合的复杂过程，是一个要涉及协调多方面利益和目标的寻优过程。本文基于四阶段交通模型理论，使用O-D反推技术和随机用户均衡配流模型，设计了公共交通线路调整影响分析流程，达到更实际、更合理的交通分配结果。以8图层架构为基础，提出了系统总体架构，最后使用TransCAD实现系统。通过某市实际的公交路网的模拟计算，得到了合理的结果，证明了系统具有较好的应用价值。

Transit Route Adjustment and Effect Analysis System Design

Transit Route Adjustment and Effect Analysis System is indispensable for reasonable urban transit network planning,transit route adjustment and urban public transportation development.Transit route adjustment analysis is a complex optimal procedure which combines quantitative and qualitative methods,empirical and theoretical methods and creative and feedback processes.In this view,based on the four-stage traffic model theory,using O-D estimation method and stochastic user equilibrium assignment model,with the purpose of achieving a realistic and reasonable result,this paper has designed the transit route adjustment and effect analysis procedure.Based on an 8-layer system architecture,the system is constructed under TransCAD platform.The system has been proved to be valuable in application since the simulation results which are based on a sample system integrating real transit network of a city are reasonable.
