Abstract
While bicycle mode is desirable from the viewpoint of global environment, illegal on-street parking damages local environment typically in railroad station plaza. An efficient way of enforcement activity is required which takes account of bicycle user's behavior. First, how bicycle users perceive the level of enforcement activity, such as penalty and probability of being enforced, is examined. Second, bicycle user's perception of other user's compliance, which is reflected in their choice of access mode to railroad station through social interactions, is studied. Finally, access mode choice models are estimated with discrete choice theory, by which I conclude that the level of enforcement affects bicycle user's behavior in several ways. The impact is also dependent on the perception of enforcement activity.
