Program managers within state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) are charged with organizing a chaotic universe of identified renewal needs into a logically sequenced program of manageable projects. In addition, the sequencing is expected to maximize available resources and minimize disruptions to the travelling public and to adjacent land uses. Over the past several years, substantial progress has been made in the areas of performance measurement, maintenance of traffic, mitigation of congestion in work zones, and alternative contracting and construction techniques. This progress has been made in studies and planning designed to minimize, manage, and mitigate disruption to traffic and commerce arising from renewal programs. In application, however, impacts of highway renewal activities are analysed largely at the project level and not at the program (mesoscopic) level, where time and cost savings can be optimised.
