Abstract
The effect of removing illegally parked bicycles on bicycle user behavior is unclear. To examine the structure of illegal parking and its relation to bicycle removal, questionnaire surveys about illegally parked bicycles, their removal, the places where removed bikes are stored, and the places where bicycle parking is currently allowed in the Tenjin area of Fukuoka City were conducted. Results of the analysis are as follows. (1) 73% of current users of bicycle parking facilities had parked illegally before using parking facilities; it is thought such users were successfully convinced to start using the parking facilities. (2) The relationship between bicycle removal and parking behavior following removal was formularized and explanation variables were estimated. (3) Rising fees for storage can potentially prevent those who have had their bicycles removed from continuing to use them. (4) More thorough bicycle removal will decrease the rate of illegal parking and increase the use of parking facilities, but the effect is not large.
