Scheduling Urban Infrastructure Renovation Projects to Minimize Traffic Disruption

We address the integrated problem of scheduling renovation projects and corresponding construction transport, with a focus on the renovation of bridges and quay walls. Over time, these pieces of infrastructure need to be replaced. Such renovation projects have a large impact on local traffic; each project generates construction traffic and often temporarily disables local roads and waterways, disrupting both road- and water-based traffic in the surrounding area. Scheduling of renovation projects needs to minimize project lateness to avoid dangerous situations due to neglected infrastructure, while avoiding excessive congestion due to parallel renovation projects that lead to increased emissions and time loss for traffic participants. Additionally, constraints with respect to resources (such as material and equipment) and availability of transport routes for these resources have to be accounted for. While previous papers have investigated the scheduling of renovation projects (Cheu et al., 2004; Gong & Fan, 2016), none have included resource constraints and transport planning in the scope.
