abstract
The Federal Highway Administration and the Texas Transportation Institute recently sponsored a research project to determine the most effective strategies, or combination of strategies, related to construction, traffic management, or public information when initiating pavement preservation, rehabilitation, or reconstruction activities in high-traffic environments. To assist state highway administrators (SHAs) in utilizing the information from this investigation, a series of decision-support matrices was created: (a) a preliminary strategy selection matrix; (b) more detailed matrices focused on construction, traffic management, and public information strategies; and (c) an interdependency matrix that considers synergy among multiple strategies. Application of these matrices is a three-step process. First, based on existing or anticipated local conditions and priorities, the preliminary strategy selection matrix supports selection of initial construction, traffic management, and public information strategies. Second, with initial strategies identified, the more detailed secondary strategy selection matrix supports refinement of the preliminary set of strategies based on their relative impact and identifies project examples where each strategy was applied. Third, with a reduced set of strategies for consideration, the strategy interdependency matrix suggests whether combined strategies may provide an additional synergistic benefit if simultaneously applied. The development of this matrix-based decision support tool is intended to encourage a more informed, broader consideration of construction, traffic management, and public information strategies, resulting in reduced impacts to road users, proximity businesses, and residences and reflecting positively on SHAs. This effort has generated early interest by SHAs, suggesting significant and timely perceived benefit.
