基于道路平面交叉口安全的视距评价

平面交叉口是整个道路网中安全较为薄弱的环节,每条车道都应该能为驾驶员提供足够的视距来保证行车的安全.针对于交叉口视距评价问题,文章阐述了二维停车视距模型和模型的计算方法,给出了不同类型交叉口处的视距评价方法,并利用视距三角形对泰州某些具体交叉口展开视距安全评价,提出了改善措施,可为保障交叉口视距和提高交叉口安全性提供参考.

Visual Range Evaluation Based on Road Intersection Safety

Plane intersection was a weak link in the traffic. Every lane should provide enough visual range for the drivers to ensure driving safety. In allusion to the intersection visual range evaluation, this article stated the two-dimensional parking stadia model and calculation method of the model, and gave different evaluation methods of different types of intersections. By using the stadia triangle model, safety evaluation of some intersections in Taizhou was carried out and some improving measures were raised. It could provide a reference for ensuring intersection visual range and increasing the safety of the intersection.
