A model of crosswalk placement aimed at jaywalking restraint

Abstract

In this study, the pedestrian crossing behavior is discussed using the interventing opportunity model. By modeling pedestrians' decision making about crossing, the possibility of carring out jaywalking is derived. Based on this, the mathematical programing problem is formulated to maximize the possibility of pedestirans' choosing a route of using crosswalk, and the optimal crosswalk placement is analyzed. Through the possibilities related to pedestrians' choice of crosswalk changes parametrically, it is confirmed that these values affect the optimal crosswalk placement and the value of objective function. This mathematical model can apply to other situation coexisting continuous and discrete opportunities.
