Comparison of Alternative Pedestrian Crossing Treatments

The proposed study will determine the conditions in which the in-street sign gateway treatment can be substituted for more expensive Rectangular Rapid Flash Beacons (RRFB) and Pedestrian Hybrid Beacon (PHB) treatments. The results of this research will assist the Michigan Department of Transportation (MDOT) in determining how to maximize pedestrian safety benefits with limited financial resources. Evaluating the impact of the in-street sign gateway treatment in a variety of different crossing applications could help identify potential applications of this treatment option. It is also important to determine how much the visual narrowing effect of the gateway treatment contributes to the effect and whether similar effects could be obtained by using delineators without the in-street sign message. Another issue of interest to MDOT is how to extend the useful life of in-street signs. One way to reduce damage to these signs is to vary their placement in the roadway. There are a number of placement strategies that could extend the life of these signs, which should be evaluated.
