基于三维动态模型的桥梁与公路视觉安全协调性评价研究

近年来，随着我国交通事业的快速发展，交通安全问题越来越受到人们的关注。公路和桥梁是交通系统中的重要部分，应保证其使用的安全性。为了评价桥梁与公路系统视觉安全方面的协调性，保障交通安全，从道路使用者的视觉特性入手，深入分析桥梁与公路视觉安全协调性的各组成要素并建立三维动态仿真模型。在三维模型的基础上，研究桥梁与公路视觉安全协调性构成的要素，确定桥梁与公路视觉安全协调性影响评价的指标体系及其评价因子，提出以桥梁和公路视觉安全为评价尺度的桥梁与公路视觉安全协调性评价体系。

Evaluation Research on Visual Safety Coordination of Bridges and Highways Based on 3D Dynamic Model

In recent years with rapid development of China national transportation industry, traffic safety problems have been more concerned by people. Highways and bridges are important parts of traffic system and their safety in use should be guaranteed. In order to evaluate coordination of bridge and highway systems in visualsafety and guarantee traffic safety, this paper deeply analyzes various components of visual safety coordination of bridges and highways and establishes 3D dynamic simulation model by starting from visual characteristics of road users. On the basis of 3D model, the paper studies components of visual safety coordination of bridges and highways, determines index system and factors of evaluation for influences of visual safety coordinaiton of bridges and highways, and proposes an evaluation system for visual safety coordination of bridges and highways with visual safety of bridges and highways as evaluation criterion.
