【摘要】：公路交通是社会发展的支柱产业，也是我国交通运输的主要动脉。近年来，公路交通的飞速发展带来了经济的大幅增长，可同时也带来了越来越频繁的交通事故。迄今为止，我国的交通事故死亡人数已经连续十余年位居世界第一，安全审计刻不容缓。我们不仅需要对建成道路的事故多发点进行治理和改进，，更需要通过分析研究安全评价方法来完善道路设计，从根本上减少交通事故，提高公路安全水平。本文结合国内道路安全评价的现状，通过对美国交互式道路安全设计模型IHSDM的深入研究，对软件的高速公路模块在中国的应用进行了初步的探索，并通过对软件的事故预测模块和设计一致性模块的修正，建立了一个适合中国的高速公路安全评价体系。为解决国内高速公路安全评价系统不成熟的问题，完成设计模型中的事故预测模块和设计一致性模块的修正和改进。其中在事故预测模块中结合国内高速公路预测模型，对软件的高速公路事故预测进行回归分析，并划分路段类型分别对软件计算结果进行修正，使软件经过改进后可以在国内进行应用，弥补国内高速公路事故预测的欠缺。在设计一致性模块中对其核心算法和评价流程深入研究，并结合国内经典运行车速模型，对模块的核心算法加以修正，使得软件在修正后可以在国内对道路的连续性、一致性进行评价。经过改进修正后软件可以在国内对新建及改扩建公路项目进行安全性评价，有效预防交通事故，减少公路运营费用，最终取得较好的投资回报。
[Abstract]:Highway traffic is the pillar industry of social development and the main artery of transportation in our country. In recent years, the rapid development of highway traffic has brought about a large economic growth, but also brought more and more frequent traffic accidents. So far, The death toll of traffic accidents in our country has been ranked first in the world for more than ten years in a row, and the safety audit is urgent. We not only need to deal with and improve the accident prone areas where roads are built, It is necessary to improve the road design by analyzing and studying the method of safety evaluation to reduce traffic accidents and improve the level of highway safety. Combined with the current situation of road safety evaluation in China, this paper makes a preliminary exploration on the application of the software freeway module in China through the in-depth study of the interactive road safety design model (IHSDM) in the United States. By modifying the software accident prediction module and design consistency module, a freeway safety evaluation system suitable for China is established. In order to solve the immature problem of the domestic expressway safety evaluation system, the accident prediction module and the design consistency module in the design model are revised and improved. Regression analysis is carried out on the expressway accident prediction of the software, and the results of the software calculation are revised by dividing the road sections, so that the software can be applied in China after the improvement. In the design consistency module, the core algorithm and evaluation process are deeply studied, and the core algorithm of the module is modified by combining with the domestic classic running speed model. After modification, the software can evaluate the continuity and consistency of roads in China. After improvement, the software can evaluate the safety of new and expanded highway projects in China, and effectively prevent traffic accidents. Reduce highway operating expenses, and finally achieve a better return on investment.
