Evaluation of highway route design based on computer simulation

对公路设计评价方法进行了研究,提出了基于计算机仿真的公路设计安全评价方法。对公路的特点和设计评价手段进行了分析,提出了建立公路仿真系统,对设计方案和设计指标进行评价的思路。分析了公路仿真系统的特点,建立了基于Multi-Agent的仿真系统框架。通过建立计算机仿真模型--汽车模型、驾驶员模型和公路模型,仿真汽车在公路上的运行情况,得到汽车的运行速度、加速度等定量指标,从而对公路设计指标进行评价。通过计算机仿真,可以使设计人员在设计阶段就可以发现设计存在的问题,及时修改设计,提高设计的科学性、合理性。

Authors discuss the evaluation model of highway design and propose a method of highway plane safety design based on computer simulation. By analyzing the character of highway and methods of highway design evaluation, the idea of building highway simulation system which evaluates highway design is put forward. The Multi-Agent framework of simulation system is built according to the characters of system. By constructing computer simulation models that are vehicle model, driver model and highway model, the performance of vehicle is simulated. And the highway criterion is evaluated by the running speed and acceleration of vehicle. By computer simulation, the designer can find the problems of design in designing phase so that the scientificity and reasonableness of design can be promoted.
