摘要
交通冲突技术是一项近似事故的安全评价方法,具有许多事故评价不可比拟的优点.冲突严重度判别是交通冲突技术中非常重要的一个环节,一般采取距碰撞时间(tTTC)作为指标.但是由于传统的冲突技术最初是在人工观测的背景下开发出来的,因此冲突严重度的判别相对依赖人工经验,不够精确,因此不利于实现自动冲突检测.本文试图将模糊控制思想引入交通冲突严重度判别来解决这些问题,并相应地提出两种实用的方法及讨论了如何将其用于实时动态自动监测交通安全.
The traffic conflict technique （TCT） is a near-accident evaluation of road safety. Compared to the accident statistics, this promising method for assessing the level of the safety has some unique advantages. The estimation of severity of conflicts is an important building block of TCT with Time-to-collision （tTTC ） as an indicator. Un- fortunately, because this technique is developed based on human-being observation, there have been some problems on determining the severity of the traffic conflicts, such as dependence on human experience and the inaccuracy of the result which is not convenient for automatic monitoring. This paper attempts to introduce the fuzzy logical control method to overcome these problems and to apply it to real-time road safety monitoring by proposing two practical methods.
