摘要: | 西部滨海纵贯公路改善计画系政府十四项重大建设之一,其中台十五线,(关渡桥-香山段)于民国八十七年七月改善完成,对于提升行车效率有正面效益。但通车后肇事率与肇事严重性有偏高之现象,因此本研究透过肇事资料之搜集分析依所建构之评定模式确认易肇事地点,分析其肇事原因,据以研拟改善对策,以减低肇事之发生机率及严重性。 本研究以新竹县市境内西滨西快路段为研究范围,就其最近一年半内所发生之肇事资料,首先依易肇事危险绩效值,评定易肇事地点;其次再依肇事型态,肇事原因,研拟相对应改善手法与改善措施后经检讨分析其肇事原因、肇事类型与道路条件等相关资料予以归纳为四类主要问题分别为:交叉路口过多过密问题、道路几何条件不良问题、路型变化及速限变化衔接处问题及西快公路交通运转特性与一般公路不同产生行车安全问题,分别提出改善案例。 此外,有鉴于现行易肇事地点,一般均依民意代表建议、人民陈情或道路管理单位巡查发现缺失,而予以改善,均属零星无计画性之改善,因此有必要建立易肇事地点改善之标准作业程序,并祈统一作业流程,所需各项表格,以达标准化、程序化之目的,并提供各道路管理单位作为改善作业之参考。 The Western Coastal Penetrated-island Expressway's improvement plan is one of the government's fourteen major projects , among of them that Route Tai-15(Kuantu Bridge-Hsiangshan)has been completely finished in July,1998. It has observable positive benefits on behalf of upgrading its traffic efficiency, nevertheless, the sign of accidental rate has risen and has become more serious after operation. Therefore, this study is not only through getting accidental data to analyze, but also to build up the module of estimation for accident-prone location identity, the cause of accident analysis, and that come up with improvement measures to reduce the possibility of accident and its severity. This study is the Western Coastal Expressway in Hsinchu County and in Hsinchu City, and that the accident has taken place within one and one half of year. Initially, according to its performance value of accident-prone jeopardy estimating its location, secondly, based on its accident types and accident causes, there countermeasures are provided by means of method and step after reviewed and then main four-type issues are induced by analyzing its accident causes as well as accident types and road conditions. On the other hand, that questions are too high density of road cross, poor geometrical road condition, linking up on both road type changing and speed shifting, traffic safety is induced distinction between the operation characteristic of Western Coastal Expressway and highway are also offered its an example for improvement, respectively. Besides, owing to current accident-prone location is frequently dissolved by people's representative's proposal, people's appeal or road-inspector, that are odds and ends and out of our plan. Therefore, we need to create a standard operation procedure for accident-prone location improvement, and we pledge that unify the operation proceedings, various forms necessarily. So that, we can reach the goal of standardization as well as process and that will provide as a reference to road administration for improvement. |
