SOCIAL COST OF TRANSVERSE BARRIER EFFECTS

The purpose of this paper is to describe a four-step method for quantifying the socio-economic impacts of motor vehicle traffic on pedestrians and cyclists. Portions of the model are taken from a method described in Reyier (1986). Reyier considers two aspects of the barrier effect. They are the transverse effect, the impact on pedestrians and cyclists attempting to cross a roadway, and the longitudinal effect, the impact on cyclists as they travel in the roadway with the traffic flow. The method in this paper deals only with the transverse barrier effect.(A)
