Abstract

This study attempts to evaluate and compare the land consumption efficiencies of various urban transport modes, utilizing the time-area method. With the careful considerations of travel conditions and modal characteristics, equations for the computation of time-area for various different modes are derived. With the appropriate assumed values of parameters, time-area consumptions per person per km for each mode both for peak and off-peak situations are computed and evaluated. The relationships between the time-area consumed and operating speed for each mode are graphically demonstrated and discussed. An example of the time-area consumed for a hypothetical commuter round-trip using various modes are also presented in order to clearly show the consumption of parking requirements by specific modes. It shows that regardless of facilities used, auto users are by far the worst in terms of area efficiency and that transit, especially rail rapid transit, is a superior mode. Pedestrian and bicycle, though consuming more than expected, also demonstrate the advantage in case of a short-distance trip in terms of area efficiency compared with the bus transit modes.

본 연구는 시간-면적 방법론을 적용하여 도시교통수단의 토지소모 효율성을 비교분석하고자 하였다. 도시의 주요 교통수단을 대상으로 그간의 연구와 달리 각 수단에 적합한 교통조건과 운행여건을 고려한 토지소모효율성 산정식을 도출하였고, 도출된 식을 이용하여 각 수단별 1km 통행시의 인당 시간-면적 소모량을 계산하여 비교하였다. 또한 산정식을 이용하여 소모량과 운행속도와의 관계를 분석하여 각 수단의 소모량의 범위를 비교하였으며, 주차에 의한 시간-면적 소모량을 명확히 제시하기 위해 외곽으로부터 도심으로 통행하는 통근자의 가상 왕복통행을 가정하여 수단별 통행에 따른 총 시간-면적소모량을 비교분석하였다. 연구의 결과, 이용시설에 상관없이 승용차 이용자가 가장 소모량이 많은 것으로 나타났고, 도시철도를 포함한 대중교통수단의 효율성이 우수한 것으로 나타났다. 예상과는 달리 도보와 자전거는 높은 소모량을 보였다. 그럼에도 불구하고 단거리 통행시 버스를 대체할 수 있는 수단으로 나타났다.
