Abstract
For the future development of planning method including topographical factors, this study aims to reveal the influence of altitude and slope to mode choice. Original travel survey was conducted in Yokohama, Japan to collect revealed preference data with high spatial resolution.
By tabulated analysis, decreasing trend of walk share and increasing trend of bus and taxi along the increase of difference in elevation were revealed.
Disaggregated analysis by the development of logit model revealed that difference in elevation has a negative effect to the utility of walk. By comparing parameters, it was revealed that 1m difference in elevation is equal to 12-meter walk or 21.9 JPY payment. Also, it was revealed that difference in elevation from bus stop has a negative effect to the utility of bus and 1-meter difference is equal to 10.4 JPY payment.
