適地性服務運用於交通傳報系統之設計與實作
DESIGN AND IMPLEMENTATION OF A LOCATION-BASED MESSAGING SYSTEM
摘要
即時路況的通報對行駛中的駕駛員是最重要的資訊，而藉由車機設備接收訊息、收聽廣播及電子看板的提示都是目前取得即時路況的主要方式，但由於上述方法須透過事發者聯絡道路警察，或透過廣播來提醒駕駛員發生意外的路段，所以會延遲訊息傳遞的時間，但是廣播訊息並不屬於適地性資訊，所以會造成駕駛員接收訊息的不便。車載隨意網路中，車輛通訊的組成方式主要可藉由車輛之間短距離的通訊設備及連接到路旁的無線基地台以進行溝通，本研究為解決上述問題，首先整合車載隨意網路中訊息的傳遞機制（車對車的通訊、車對道路設施的通訊及車隊建立的方式等）於系統的各項功能中，並針對不同的駕駛環境（市區、高速公路及隧道等）而設計系統的組成方式，再透過車隊管理及適地性服務的概念，實作一個適合用於車間及車隊溝通之系統，透過相同區域內的車輛之間相互傳遞資訊，以降低傳統訊息傳報所花的時間及提升訊息的有效性，達到提前預警的效果，並提升駕駛員及乘客的行車品質，最後透過問卷評估的方式針對計程車、運輸業者及一般大眾的接受程度進行調查，其結果顯示受測者對本系統的接收程度超過80%，可證明本研究極具開發價值。

Highway tunnel is designed to be a special space of meeting traffic transportation requirement. Its efficacy doesn’t only save time for drivers but also promotes social prosperity and regional development. However, highway tunnel is a semi-closed environment. Once serious disaster occurs inside tunnel, it is very difficult for people inside who want to escape from disaster or disaster relief personnel from outside to conduct rescue. Therefore, in preliminary period of tunnel design, except various disaster prevention measures are cautiously planned, behavior characteristics are considered, accident and risk control on tunnel is conducted, how to apply information technology in highway tunnel to provide and deliver emergent accident messages to vehicles driving in tunnel in case accidents appear, furthermore, start relevant security mechanism to allow people inside tunnel to clearly understand escape direction, send message to fire fighters and citizens outside tunnels for making detour, so as to reduce difficulty of rescuing people, is a very important topic. This research creates a real-time communication system suitable to be used during driving for drivers, with the purpose to remind drivers and passengers inside tunnels of location, distance and escape direction concerning accidents, also remind drivers not entering tunnel of replacing drive route, so as to reduce occurrence probability of disaster accidents and maintain life security of road users. This study integrates inter-vehicle communication and mechanism concerning positioning, discusses and evaluates acceptance of this system by users through questionnaire finally. Through analysis results, most respondents show their agreement on this system, which proves that our system is acceptable by a majority of respondents.
