Abstract

This study examines the effect of a law enforcement program implemented to check illegal and unsafe motorist and pedestrian behavior. A case study involving eight selected intersections in Las Vegas (four control and four treatment) was carried out over a period of seven months in conjunction with the pedestrian law enforcement program conducted during March and April of 1996. Pedestrian and motorist behaviors were video taped in 120 minute segments. The tapes were then reviewed to count vehicle violations, pedestrian violations, conflicts, total vehicles and total pedestrians. Violations and conflict rates for pre and during enforcement, and pre and post enforcement phases were compared using the Wilcoxon signed rank test - matched pairs. Regression analyses were then conducted to determine the effect of intersection design characteristics on violations and conflicts; The results from the nonparametric statistical tests suggest that the law enforcement program did not have any long term impact on reducing pedestrian violations, vehicle violations and conflicts. The results from the regression analysis identified "pedestrian volume" as a significantly consistent explanatory variable for the dependent variable "pedestrian violations". Likewise "vehicle violations" and "with signal outside crosswalk violations" showed up as significantly consistent explanatory variables for the dependent variable "conflicts".
