Study on Highway Safety Simulation Evaluation Model and Method

We analyzed the characteristics of highway simulation system; established framework for a Multi-Agent based simulation system, and identified the construction framework for the highway safety simulation model. Through constructing computer simulation models – vehicle model, driver model, road model and barrier crash simulation model – to simulate vehicle operation on highway, we obtained quantitative indices such as operating speed, acceleration, and brake requirement, and evaluated highway design specifications. In consideration of specific highway project, we analyzed and evaluated the application effect of the simulation model in alignment safety evaluation and barrier setting safety evaluation, confirmed that the practicality of the simulation model. The result showed that computer simulation can help designers find design problems during the design period, make timely correction, and improve the scientificity and appropriateness.
