Abstract:

Transportation agencies routinely travel their extensive roadway networks conducting subjective roadway ; assessments of traffic control devices both day and night. Retroreflectivity is a good tool for product testing ; but can provide false positives for traffic control devices based on the approach geometry. This research ; project developed an objective nighttime assessment method for traffic devices that could be tied back to a ; form of level of service. The project also correlated luminance data with level of service. Researchers ; recommend the use the precise and approximate measurement methods in conjunction with nighttime ; inspections and retroreflectivity measurements to assess the accuracy and repeatability versus time.
