台灣地區省道公路指示標誌系統改善之研究

Abstract

良好的公路指示標誌系統，可協助用路人配合地圖順利到達目的地。政府投入相當經費在指示標誌的設置，但用路人對指示標誌滿意度卻不見提高。因而有必要對省道指示標誌的現況進行檢討與改善，使其發揮行車導引功能。 本研究主要目的在探討省道指示標誌之現況缺失，並建構指示標誌之規劃程序，透過系統化的規劃流程，期能改善現有指示標誌系統。本文首先進行省道指示標誌現況分析與檢討，其次針對用路人感受進行調查與分析，再依據現況缺失及用路人感受，參考國內、外公路指示標誌設置的法令規範及相關文獻，建構符合台灣本地特性之指示標誌規劃程序。其主要特點有： 1.對於省道公路指示標誌之設置，能有一套標準作業流程。 2.依據導引資訊之性質將指示標誌進行分類，並依照不同層級公路所具備之服務功能配置導引資訊。 3.地名資訊之選擇符合都市層級劃分，利於用路人配合地圖行車。 4.對於高（快）速公路及交流道指引標誌之設置，能有可資依循的明確準則。 經由個案研究之差異分析結果，透過建構的規劃程序，對於指示標誌之設置能有一套系統化及標準化之作法，進而可改善目前省道公路指示標誌的主要缺失。

A well highway guide sign system could help highway users to arrive their destinations by maps easily. Although the government has invested a great amount of money in placing guide signs, highway users still not satisfied. In order to increase the function of the guide sign system, it is necessary to examine the problems of current provincial highway guide signs and propose measures of improvement. The purpose of this research is to explore the current problem of the provincial highway guide signs and to develop a systematic procedure. Through the systematic planning procedure, it could improve the guide sign system dramatically. First of all, this research examines the major problems of current guide sign system of provincial highways. Second, it analyzes the opinions of highway users by conducting questionnaire survey, and then develop a guide signs planning procedure that fits Taiwan’s local situation and requirement based on the laws, rules and literatures from Taiwan and abroad. The major characteristics of the procedure are: 1.It provides a standard operation procedure for the installation of provincial highway guide signs. 2.It categorizes the guide signs by the characteristics of guidance information, and provides different information for different service function class of highways. 3.The selection of the place name fits the urban hierarchy. This will make highway users easier to drive following a map. 4.It provides a clear set of guidelines for the placement of freeways (expressways) and interchange guide signs. According to the result of case study, if the guide signs were installed following the procedure proposed in this study, it will improve the major problems of the current provincial highways.
