NCHRP Project 17-56: Development of Crash Modification Factors for Uncontrolled Pedestrian Crossings

The objectives of this research are to (1) quantify the relationships between pedestrian safety and crossing treatments at uncontrolled locations (excluding roundabouts) and (2) develop CMFs by crash type and severity for (a) unsignalized pedestrian crosswalk signs and pavement markings, including advance yield markings; (b) high-intensity activated crosswalk (HAWK) signals; (c) rectangular rapid flashing beacons; (d) pedestrian refuge areas; (e) curb extensions; (f) in-pavement warning lights; and (g) high-visibility crosswalk marking patterns. The quality of data used should facilitate inclusion of the CMFs into the AASHTO Highway Safety Manual.
