Optimization of Renewal-Based Project Scheduling in an Urban Network

In this paper the authors develop a mathematical decision model and solution algorithm to evaluate the impact of sequencing work-zones before construction starts at the corridor/network level. The model quantitatively measures the traffic impact/delay caused by work-zones for the entire construction period, and specially consider the daytime/nighttime construction strategies comprising of both user and agency costs, precedence, etc. In the algorithmic approach, they use a heuristic to measure user cost by examining combinations of user equilibrium (UE) assignments and use an approximation approach to approximate the UE travel time. Such an approach enables the evaluation of user cost at the corridor/network level, meanwhile maintaining computational tractability. A small hypothetical numerical example is conducted with fairly good computational performance.
