摘要

本研究結合新竹市計程車GPS軌跡資料庫與記名問卷調查來進行計程車司機路線選擇行為分析。在GIS中選擇新竹都會區11個重要地標，針對現職76位司機行駛之25對起迄點路線進行分析；25對起迄點中有14對起迄點所有計程車司機路線是固定的，但是另外11對起迄點計程車路線選擇卻有很大差異。從計程車GPS軌跡資料庫分析四個路線選擇課題，結果顯示司機們選擇路線會考慮個人的偏好、天氣以及時段。問卷調查也顯示尖離峰時間、交通擁塞干擾、天氣狀況為影響司機路線選擇之主要因素。依據司機路線選擇行為可以將76位司機分成兩群，單一路線群的司機對於「交通速限高低」、「測速照相」、「號誌個數及等候時間」及「車禍發生頻率」等四個不會隨時間而變動的因素較多路線群司機偏好高；多路線群對於「沿路人潮多寡」、「沿線商家多寡」、「天氣狀況」及「尖離峰時間」等四個會隨時間而變動的因素較單一路線群司機偏好高。

This study combined questionnaire survey data and Hsinchu City ITS taxi Global Positioning System (GPS) database to analyze taxi route choice. Eleven important GIS landmarks in Hsinchu area are chosen to define twenty five ODs (Original and Destination). Seventy-six taxi drivers were surveyed and all their traveling routes of twenty-five ODs were analyzed from the ITS taxi GPS database. While taxi drivers traveling the fourteen OD-routes are all the same with the corridor highway network restrictions in Hsinchu urban area, however, seventy-six taxi drivers traveling the other eleven OD routes are quite different. According to these routes from GPS taxi database, four route choice subjects are studied. The results show that taxi drivers who choose the routes take into account individual preferences, weather and traveling time periods. In addition, questionnaire analysis results show that the most three influencing taxi drivers route choice behavior factors are the off-peak hour, the traffic congestion interference and the weather conditions. Consequently, taxi drivers are grouped into Single-route group and Multi-route group by their the route choice behavior. Single-route group drivers take more account of four non-time-varied factors, level of traffic speed limit, Speed camera, the number of signals and waiting time and accident frequency, than Multi-route group drivers. Nevertheless, Multi-route group drivers take more account of four time-varied factors, size of the crowds along the road, the number of businesses along the route, weather, and off-peak hour, than Single-route group drivers.
