TRAFFIC SIGN RETROREFLECTIVITY ASSESSMENT AND INVENTORY

  • Integrating state of the art advanced lighting and artificial vision techniques in an instrumented vehicle operating at night at highway speeds, AMAC safely, quickly and cost-effectively assesses the actual performance of traffic signs and pavement markings.

  • The AMAC system delivers a wide range of sign panel characteristics which include retroreflectivity of both the legend and background of each sign panel. Data is delivered in user friendly formats that can be integrated into GIS and maintenance management systems.

  • Research has shown that a sign management program that utilizes measured retroreflectivity realizes significant cost savings over the functional life of sign sheeting materials. Alternate sign management approaches to sign assessment lead to material waste and signs being replaced significantly prior to their functional degradation
