This study formulates a commuters' mode and route choice model as well as a households' residential choice model on a two-dimensional space. The commuters' mode and route choice model assumes that commuters select the mode and route alternative based on the least generalized travel cost. The households' residential choice model is formulated to maximize households' residential utilities subject to time and budget constraints. A simulation method is adopted to simulate household choice behavior and solve the households' residential location choice model with two-dimensional decision variables to prevent aggregation bias. A case study for Taipei metropolitan area is illustrated to analyze the variations of residential location choices for households working in the central business district (CBD) after different lines of Taipei Rapid Transit System are completed at various stages. Results indicate that (1) there is increased attraction of households in cities of Taipei County such as Pan-Chiao, Chung-Ho, Yong-Her, and Hsin-Tien due to the completion of rail transit networks and (2) residential locations better served by rail transit lines attract more households; thereby, resulting in higher residential densities.

This study explores how transportation external cost pricing and transit fare reductions impact household mode/route choices and environmental improvements in a metropolitan area. A household mode/route choice model and a bilevel model for transportation external cost pricing and transit fare reductions are sequentially constructed. In the first level of bilevel model, the pricing of transportation external costs, including congestion, air pollution, and noise, is measured applying the theory of marginal-cost pricing. The effects of transportation external cost pricing are analyzed in terms of variations in household mode/route choices, increased patronage of rail transit lines and reduced congestion, air pollution, and noise. In the second level of bilevel model, this study explores how to reduce rail transit fares to achieve equivalent benefits of environmental improvement as for the strategy of transportation external cost pricing. The analytical results reveal that, after the implementation of transportation external cost pricing and taxation, the number of commuting households attracted to rail transit lines will increase, and some commuting households may detour to more distant transit stations to avoid high congestion links on surface streets.
