|摘要: ||由於都會區的生活行態, 大眾運輸系統與道路佈圖的錯綜複雜常是民眾心目中常存的『痛』。雖然目前已發展出不少地理資訊系統試圖幫助民眾解決這些問題, 但卻常因功能不完整而無法完全滿足使用者需求。近來, 有所謂的全球測位系統以近乎『夢幻式的完美』來導航行的問題, 然而它的價格、限制, 以及可能產生的導航誤差, 卻常令人卻步。 本文是以行路資訊系統中使用者的需求觀點為出發點, 並論及台北市行路資訊系統(ROPE)的設計理念及其規劃實作。ROPE系統中,對資訊的表示與處理是使用乏確式框架(提供位址查詢與開車定向導航功能等); 在路線規劃方面, 運用知識庫以及Dijkstra演算法, 採用考量人的思維的規劃方式。與GPS全球測位系統的比較中發現, ROPE系統不需要有GPS額外的硬體及定期與衛星定位的費用, 並擁有比GPS系統較多的優勢與功能。|
Due to the metropolitan livelihood, public transportation system and road topology is so complicated that bring vital problems to people who live there. Although traditional GIS software as well as the computer solves the problem in some degree, users always find some thing frustrated within such systems. Late GPS system inspire some kind of fancy assistance in leading the WAY. However, GPS is not only costly but also constrained or even inaccurate in doing the leading. This paper focuses on rational within the design of Route Planning information system in Taipei City (ROPE). ROPE could be considered as a brand new kind of GIS that start with the satisfaction of user requirements for such system. Within ROPE, some fancy frames had been proposed and some function had also been implemented (e.g, the address inquiry, driving direction location, common- knowledge based route planning, ... etc). When compared with GPS system, ROPE could be ever better and without any additional cost.
