Abstract Extensive research has found that people are more likely to choose the transport alternative which offers shorter travel time. But few studies approached the role of travel time across different transport alternatives and cities. This research assesses the influence of competitive travel time between car and public transit in public transit modal share for commute trips. Sao Paulo, New York, and Tokyo were selected to perform the analysis. A Fractional Logistic Regression in the binary form was drawn, and a competitive travel time index was calculated based on the Car/Public transit travel time ratio weighted by the number of the employed population at the origin and jobs at destinations in the absence of an Origin-Destination matrix. Findings suggest that, though car ownership was identified as the major factor, Car/Public transit travel time ratio is positively associated with the increase of public transit modal share. Furthermore, the Car/Public transit travel time ratio effect in public transit modal share consistently increases as people get increased access to cars.

给公共交通一个机会：公共交通方式份额中竞争出行时间的比较分析

摘要 大量研究发现，人们更有可能选择出行时间更短的交通工具。但很少有研究探讨不同交通方式和城市之间旅行时间的作用。本研究评估了汽车和公共交通之间的竞争出行时间对通勤出行的公共交通方式份额的影响。圣保罗、纽约和东京被选中进行分析。绘制了二元形式的分数Logistic回归，并根据出发地就业人口数和目的地就业人口数加权的汽车/公共交通旅行时间比计算出有竞争力的旅行时间指数。 -目的地矩阵。调查结果表明，虽然汽车拥有量被确定为主要因素，汽车/公共交通出行时间比与公共交通方式份额的增加呈正相关。此外，随着人们越来越多地使用汽车，公共交通方式份额中的汽车/公共交通出行时间比效应不断增加。
