| With the advent of the 1988 Manual on Uniform Traffic Control Devices, the procedure for warranting pedestrian traffic signals in the United States was significantly revised. This dissertation examines the application of the warrant by the New York City Department of Transportation and introduces a proposed revision based upon pedestrian-vehicle conflict rates. Prior research has indicated that conflict rates serve as a good predictor of accident risk. Since pedestrian traffic signals are intended to reduce accident risk, a warrant based upon pedestrian—vehicle conflict rates is appealing.; This dissertation outlines the development and application of the proposed warrant. In addition, a Level of Service Criteria for Unsignalized Pedestrian Crossings is also introduced. |
