Abstract
This paper proposes a pedestrian's route choice model considering the effect of physical conditions on the street. On the street in a central city area, it is generally thought that a pedestrian density and a signal system affect a pedestrian's route choice more than other basic conditions affect. We suggest the model in which new factors like a pedestrian density and a signal system are added to the basic conditions. With respect to an individual difference and an occasional difference, the former and the latter are expressed as a probability distribution and a threshold method, respectively. The results of applying the model to an actual city area reveal the relation between a pedestrian's decision-making about the route choice and various conditions on the street, and show the possibility of pedestrian guidance or inducement by a road maintenance and improvement.
