FREEWAY STYLE DIAGRAMMATIC SIGNS IN NEW JERSEY

Ninety-four freeway style diagrammatic signs were installed on I-287 in New Jersey, replacing 120 conventional signs at 22 interchanges. Traffic volumes and specific unusual maneuvers were counted and categorized for a seven-day period at each of 10 exit sites, both before and after the guide sign changes. The evaluation of the signs includes statistical comparisons of unusual maneuvers rates as well as visual observations. Diagrammatic or conventional signs were examined for their potential effectiveness according to the exiting situations. The adequacy of the diagram standards used for the study sign designs were reviewed and recommendations for further research are made for the sign designation of lane drops at exits, exit ramp geometry and the use of intermediate signing.
