Applying Land-use Transport Integrated Model for Analyzing Long-term and Comprehensive Effect of Tram in the City of Suwon, Korea

Abstract

Introducing a tram in a city would affect not only its transport system but also land-use pattern. In this study, Seoul Metropolitan Area Model developed using DELTA (land-use model) and Omnitrans (transport model) was applied to simulate the comprehensive effect of the new tram for the City of Suwon. Before applying the model, the parameters of Omnitrans were calibrated and validated. Three scenarios were set up to analyze the long-term effects of mode choice and the subsequent changes in land use and population: a business-as-usual (BAU) scenario and two alternative scenarios with a tram and an increase of floor area ratio (FAR) in the adjacent area of the tram route. The model simulation showed that introducing a tram route would reduce transit use as a result of decreased accessability to the city rail station using bus and car, which is ascribed to the bypass of bus routes. The simulation also showed that the residential location of younger householder families might change from downtown to outskirts, because the tram would decrease the accessibility to the jobs outside the city. However, the elderly householders move to downtown due to the tram and reduced housing rent. This problem might be solved by introducing more tram routes throughout the city and modifying the bus routes appropriately. Its effects are to be explored using a model with actual tram traffic data in the future.
