都會區內場站與快速道路配置型態對高鐵與航空市場範圍之影響

Effects of Metropolitan Terminal and Expressway Configuration on the Market Areas of High Speed Rail and Air Transport

本研究針對服務同一城際運輸走廊的高鐵與航空惡統，探討城際運具選擇相關特性。考慮高鐵與航空的特性，場站位置，都會區內路網型態，有無快速道路通過場站，以及旅客之需求特性，如旅次長度、產生時間、時間價值、起迄點位置等，建立解析性模式，並使用理論推導的方式，透過一般化總旅行時間之比較來探討都會區內旅客選擇高鐵與航空之行為，且求算出特定場站、路網規劃配置與營運策略下，都會區內高鐵與航空的市場範園大小品研究結果顯示，有無快速道路，快速道路速度，旅客的旅次長度、時間價值，高鐵與航空的班次、平均速度、票價，場站相對於起迄點之位置，皆可能改變都會區內高速鐵路與航空的市場範園。本研究亦可作為旅客從事城際運輸時之決策參考。

This study develops an analytical model on the market areas of high speed rail (HSR) and air transport (AT) serving a medium to long range intercity corridor. Supply and demand attributes such as HSR and AT operating characteristics, terminal locations, expressway locations and speed, trip length, departure time, and origin and destination (O&D) locations are considered. Passengers' optimal choices are assumed by minimizing their generalized travel time. The resu1ting HSR and A T market boundaries are analyzed subject to various conditions. The resu1ts show that expressway locations and speed, passengers' trip length and time values, HSR and A T schedules, speeds, and prices, and terminals and trip O&D locations, all may change the market areas of HSR and AT serving a metropolitan area.
