| Summary: | 碩士 === 國立交通大學 === 交通運輸研究所 === 88 === Research on price elasticities of rapid transit system provides insights into how riders respond to price changes and is valuable for developing effective pricing policy. This study employs multinomial logit and nested logit models to examine the choices of primary modes and rapid transit access/egress modes. Various fare and service elasticities are computed from these choice models.
The empirical analysis, using the data collected in the Taipei metropolis area, indicates that socio demographics and level of services are important factors affecting urban mode choice, and the nested logit model with bus, rapid transit—walk access and rapid transit—bus in a nest, is statistically superior to the multinomial logit model. The elasticity estimates demonstrate that rapid transit riders are insensitive to changes in fares and are approximately two to four times as sensitive to changes in travel time as changes in fares and off-peak time users tend to be more sensitive to fare changes and less sensitive to time changes than peak users.
Different Policy scenarios related to changes of price and service characteristics are also evaluated. The implications for time-of-day fare program and fare bus transfer policy are discussed.
