交通仿真在交叉口优化设计实验中的应用

中心线偏移是交叉口优化设计措施之一,中心线偏移后,交通指标会发生相应变化,交通设计教学过程中,从理论计算上分析各项指标,直观性不强,影响教学效果,现实中此类设计方案验证不可能在课堂教学中完成,应用仿真软件开发中心线偏移前后的仿真模型,学生借助模型完成仿真实验,可以直观感受优化后的效果,也能应用输出数据对优化效果进行评价、实验时间短、操作方便、实践证明,该方法能够有效提高交通设计课程教学效果。

An Application of Intersection Optimized Design Experiment by Simulation Technology

Move intersection center line to aside is a method of intersection designing.After optimized designing the traffic index would have some changing.In traffic design class always analyzed the index by traffic theory,so students always feel the class too Abstract to comprehend and the class efficient always lower.Reality experiment of the traffic design is hardly completed in classroom.Apply traffic simulation technology to develop a simulation model for the traffic designing experiment.After the experiment the students feel truly effect of the designing while use the output data to analyzed the index.The simulation experiment cost short time and operation easy.The excises show that simulation experiment can increase efficient of traffic designing education class.
