Crash Experience Warrant for Traffic Signals

The objective of this research is to recommend an improved Crash Experience Traffic Signal Warrant that is suitable for inclusion in the Manual on Uniform Traffic Control Devices (MUTCD), based on research and consistency with the Highway Safety Manual (HSM). If the current Crash Experience Traffic Signal Warrant is sufficient, then this research should validate the warrant. The products of this research project are intended to be used to: (1) determine whether installation of a traffic control signal at a specified intersection will improve its overall safety and (2) estimate the safety impacts of installing a traffic control signal at this intersection. The intersection may be located in an urban or rural area. The focus will be on typical intersection forms where (1) the through traffic movements cross at about a right angle and (2) STOP signs control the minor roadway. However, intersections with alternative types of traffic control and geometry will also be considered where feasible.
