Road maintenance with Opti-Grade : Maintaining road networks to achieve the best value Brown, Mark ; Mercier, Steve ; Provencher, Yves

By: Brown, MarkContributor(s): Mercier, Steve | Provencher, YvesPublication details: Transportation Research Record, 2003Description: nr 1819, s. 282-6Subject(s): USA | Conference | Road network | Measurement | Apparatus | Evenness | Speed | 33Bibl.nr: VTI P8169:2003 Ref ; VTI P8167Location: Abstract: Road management systems rely on the availability of quality information to make good decisions. A lack of information on the condition of the Canadian forest industry's unpaved road network led to inappropriate management decisions. To fill this information gap the Forest Engineering Research Institute of Canada (FERIC) developed the Opti-Grade road management system. Opti-Grade is a low-cost tool that provides information about the road roughness and travel speed as the equipped road user's vehicle travels on the road network. This information can then be used to focus grading activities where they will have the greatest impact on the road condition for the money invested. Further, over time, a history of the behavior of the roads can be built. With this history, degradation models can quickly and easily be produced to see which segments of the road network degrade the quickest and the most frequently. Problem segments can be identified. Valuable road evaluation budgets can then be focused on those sections to determine the cause of the problem. That will allow precious rehabilitation budgets to be focused where they can have the greatest impact. Opti-Grade is currently used by a large sector of FERIC member forest companies with payback periods shorter than 4 months. FERIC continues to improve the software to manage the data from the Opti-Grade system and increase the abilities of the decision support tools in the software.
