Roadway maintenance and repair has become increasingly commonplace in the United States over the past several decades as our roadway infrastructure has continued to age and deteriorate. Maintenance and repair work on an existing roadway often presents the challenge of maintaining traffic on the existing roadway while work is being performed, thereby necessitating the use of what is commonly referred to as a roadway "work zone". One …

Characteristics And Causal Factors Of Claims In Michigan Highway Construction Projects, Abel K. Sahlool

Wayne State University Dissertations

The US highway system is the largest road network system in the world. MDOT administers about 9,722 route-miles, (28,000 lane-miles) of roadway networks in Michigan. Every year, hundreds of projects worth millions of dollars are let by the State Transportation Agency (STA).

Majority of these projects are successfully completed within the original scope of work, budget, schedule, and without litigation. However; some projects end up in litigation and disputes costing tax payers a great amount of money and the STA a great amount of resources. The number and cost of these construction claims has been substantially increasing in recent years. …

Dynamic Routing On Stochastic Time-Dependent Networks Using Real-Time Information, Ali R. Guner

Wayne State University Dissertations

In just-in-time (JIT) manufacturing environments, on-time delivery is one of the key performance measures for dispatching and routing of freight vehicles. Both the travel time delay and its variability impact the efficiency of JIT logistics operations, that are becoming more and more common in many industries, and in particular, the automotive industry. In this dissertation, we first propose a framework for dynamic routing of a single vehicle on a stochastic time dependent transportation network using real-time information from Intelligent Transportation Systems (ITS). Then, we consider milk-run deliveries with several pickup and delivery destinations subject to time windows under same network …
