• Abstract:
  This research addressed an array of issues related to measuring pavement markings retroreflectivity, factors ; related to pavement marking performance, subjective evaluation process, best practices for using mobile ; retroreflectometers, sampling pavement markings, and best practices for a Pavement Marking Management ; system. Tests conducted to assess subjective evaluation showed inconsistency in subjective retroreflectivity ; evaluation when compared between different evaluations, marking color, and retroreflectivity levels. ; Sensitivity testing on several factors that could potentially affect mobile retroreflectometer readings showed ; that distance from which the measurements are taken and position across the measurement window seemed ; to have the most significant impact on the mobile retroreflectivity measurements. The evaluation factors of ; data acquisition, vehicle speed, and small changes in measurement geometry made no practical difference to ; the measurement. However, constant speed provided best results. Based on the sensitivity testing this report ; enlists some best practices for mobile retroreflectometer measurements. A methodology for combining ; mobile retroreflectivity data with pavement information and plotting a map, color coded based on pavement ; marking retroreflectivity level using GIS, are demonstrated in this project. This report also provides ; discussion on other best practices for sampling and Pavement Marking Management system.
