台湾地区高快速公路资讯可变标志最适显示运用之研析

先进交通管理系统（advancedtrafficmanagementsystems，ATMS）所蒐集之交通资讯及交通管理策略，需经由先进用路人资讯系统（advancedtravelerinformationsystems，ATIS）发布後方显现效用，其中资讯可变标志（changeablemessagesign，CMS）为驾驶者在旅途中最重要的讯息来源。CMS主要显示内容包括交通宣导讯息、即时路段旅行时间及透过事件反应计画自动显示之路况资讯等，本研究针对CMS显示幕显示字体大小、辉度、显示时间，以及显示内容研提建议。依前述原则执行後，台湾地区高速公路用路人对CMS资讯内容的满意度达86．8，〈（2010）。本研究并分析台湾地区CMS中英文双语化之可行性，受限於版面空间、反应时间、系统转换时间及无法自由选择语言之特性，无法同时显示中英文资讯，故建议以使用中文之用路人为主；惟国外旅客较多之路段，建议挑选部分CMS显示英文旅行讯息，其余路段则维持发布中文资讯。

Optimum Use of Changeable Message Sign

Advanced Traffic Management System （ATMS） collects traffic information released by Advanced Traveler Information Systems （ATIS） to achieve the effect of traffic information dissemination. The Changeable Message Sign （CMS） is the most important source of traffic information for the drivers on their trips. CMS mainly displays the traffic safety messages, real-time travel time, and the traffic information through the incident response plan automatically, etc. This study provides some suggestions to CMS, like word size, brightness, display time and message display priority. By using this principle, the degree of satisfaction of road users reaches 91% （2010） by questionnaires. This study also conducts feasibility analysis of Taiwans CMS bilingually both in Chinese and English. However, with the limitation of layout space, response time, and system conversion time and characters of being unable to choose language, CMS can not display Chinese and English at the same time. Therefore, this study tries to evaluate the optimum use of CMS. Finally, the paper selects partial CMS to display travel time in English in the road section where more foreigners will drive on.
