Traffic Jams in Japan: Does Public Transit Have an Impact?
نویسندگان
چکیده
The mitigation of traffic congestion is a growing problem globally. We test whether there is a relationship between rail provision and road performance in Japan, using aggregate level data. Our motivation for examining Japan is the comparatively high level of rail provision in Japan. A regression analysis of prefectural data from 2010 finds that the length of rail has a significant effect on average road speed. This research finds a relationship in the data, but does not necessarily imply causation. A choice model at a smaller scale may give a better indication of whether the provision of rail directly mitigates traffic congestion.
