TRB's National Cooperative Highway Research Program (NCHRP) Research Report 881: Traffic Control Devices and Measures for Deterring Wrong-Way Movements provides an analysis of factors associated with wrong-way movements on unsignalized divided highways and freeways. The divided highway analysis focuses on design, signage, and roadway markings, while the freeway analysis emphasizes the effectiveness of signage with flashing lights. The results are used to identify appropriate countermeasures and to develop specific recommendations for revisions to the Manual for Uniform Traffic Control Devices that may deter wrong-way movements by drivers.
