Abstract
In recent years, bicycle use as urban transport mode is reconsidered and modal shift from vehicle use to bicycle use is expected for reduction of environmental load on vehicle use. Generally, it is known that travel time of bicycle use is expected to be shortest if trip distance is less than 5 km and it is a valid trip distance for bicycle use promotion. However, estimation of the valid trip distance is based on the service level of each transport mode in inner area of large cities. It is considered to be different in local cities and its suburban areas because service level of each transport mode is different with inner area of large cities. In this research, valid trip distances for bicycle use promotion in local cities and its suburban areas are estimated and compared in three areas, Nakagyo Ward in Kyoto City, Muko City in Kyoto Prefecture, and Kusatsu City in Shiga Prefecture.
