臺灣地區計程車數量影響因子之研究

Abstract

適當的計程車數量對於一個城市是重要的，過多的計程車會導致駕駛人收入不佳，過少的計程車則會使計程車使用者叫車不便及候車時間長。本篇論文希望找出影響計程車數量的因子，推導出合理的迴歸式，提供計程車管理單位作為決定計程車發牌數量的參考。此外，因交通部近年編列大量預算於發展公共運輸，本研究欲探討公共運輸的使用率與計程車數量之間的關係，以提供政府對於未來計程車數量可能的變化規劃。本研究使用多元迴歸式探討可能的影響因子，同時自行設計兩個實驗驗證在文獻中顯著的兩個因子，即公共運輸使用率、無車家戶比例，是否是影響計程車數量。多元迴歸式結果顯示，人口數、公共運輸使用率兩因子是顯著影響臺灣地區計程車數量的因此，而從兩個自行設計的實驗得知，公共運輸使用率為顯著因子，無車家戶比例則不顯著，此兩者相同的結果可以確知影響臺灣地區計程車數量的因子是人口數和公共運輸使用率。

An appropriate number of taxi for a city is important. Too many taxi causes low income for taxi drivers while a shortage of it causes passengers inconvenient. This study tried to find factors that influence number of taxi, as a basis for number of license to issue. Moreover, Minister of Transportation And Communication has been trying to advance public transport in Taiwan. This study also tried to investigate the relationship between public transport usage and number of taxi so that it could be used by the government to decide what to do as public transport usage increases. This study uses multiple regression model to investigate possible factors. Meanwhile, two experiments were designed in the study in order to test two factors proved significant in the previous studies, which are public transit usage and no-car households. Multiple regression model reveals that population and public transport usage are two significant factors influencing number of taxi in Taiwan.
