The Transportation Research Board’s (TRB) National Cooperative Highway Research Program (NCHRP) has issued a request for proposals (RFP) to quantify the relationships between pedestrian safety and crossing treatments at uncontrolled locations. The project will also develop crash reduction factors by crash type and severity for unsignalized pedestrian crosswalk signs and pavement markings (including advance yield markings), high-intensity activated crosswalk signals (HAWK or Pedestrian Hybrid Beacons), rectangular rapid flashing beacons, pedestrian refuge areas, curb extensions, in-pavement warning lights, and high-visibility crosswalk marking patterns. Proposals are due November 3, 2011.
