Abstract

Reducing motorist’s speed when approaching crosswalks is an important goal in reducing the number of collision between motorist and pedestrian in crosswalks. The current study addresses this goal. The effect of gateway installation of in-street signs (one in-street sign installed between the two travel lanes in each direction and one on both edges of the roadway in each direction) on vehicle speed was evaluated on nine roads. The results demonstrated that the Gateway in-street sign treatment produced large speed reductions as vehicles approached the crosswalk and at the crosswalk. The average speed reduction was 3.8 mph at the crosswalk and 2.5 mph at the dilemma zone. The Gateway in-street sign variation has shown to be an effective method of reducing vehicle speed when approaching and entering the crosswalk, and these effects have sustained over time.
