The FHWA is sponsoring an effort to determine the visibility, safety, and durability performance of all-weather pavement markings. The Laserlux retrometer will be used to collect data at a variety of all-weather pavement marking sites in various places. Presently, 19 states participate in the FHWA effort. In the study, Graham-Migletz Enterprises, Inc. (GME) will evaluate the service life, safety, and cost-effectiveness of the all-weather pavement markings. GME's subcontractor, Midwest Research Institute (MRI), will perform the statistical analysis of the retroflectivity, accident, cost, and weather data. After new pavement markings have been installed at all test sites in each year, a working paper describing site characteristics will be submitted to the FHWA. |
