基于驾驶模拟器高速公路线形设计安全性评价

Safety Evaluation of Freeway Alignment Design Based on Driving Simulator

针对在道路施工之前很难有效地对道路线形设计的安全性进行评价,提出了一种新的道路线形设计安全评价方法,即在驾驶模拟器上构建待建道路的场景,通过提取并分析驾驶员操纵驾驶模拟器汽车在虚拟道路上行驶的客观反应指标,对高速公路的设计方案进行驾驶安全性、舒适性评价,及时发现事故隐患或对安全有不利影响的设计,减少由于设计不当给社会带来的损失及危害。

A new evaluating method was put forward to evaluate the safety of the road alignment design,since it is difficult to effectively evaluate the road design safety before building road.The new method of safety evaluation is to build up the freeway driving simulator scene,extracting and analyzing the index of objective response of drivers who drive the simulator on the virtual freeway,then using these indexes to evaluate the freeway design plan by the drivers safety and comfort driving on the virtual road.Thus it can find the hidden dangers and reduce losses and harm caused by the improper design.
