Abstract

This paper presents a Geographic Information System (GIS) based methodology to identify high pedestrian crash sites ad then select safety countermeasures based on casual factors. The methodology to select high crash sites includes identifying the problem area, the high risk zones and then the high crash sites. Two types of crash indices were used to rank high risk zones. They are based on the number of pedestrian crashes in the vicinity of the zone by severity and length of the zone. Results obtained by applying the methodology in the Las Vegas metropolitan area are discussed in this paper.
