Title Enhancing Jit Freight Logistics Impacted by Transportation System Projects under ITS.
Publication Date 2012
Media Count 18p
Personal Author A. E. Murat R. B. Chinnam
Abstract We developed an analysis methodology to support effective planning of JIT freight logistics in transportation networks impacted by system improvement projects. Currently, shippers and carriers do not have the necessary tools to predict and account for the traffic congestion impact of construction projects. Existing models used by shippers/carriers rely on historical traffic flow/congestion data from ITS and other sources. There is need for predictive tools that can be used for assessing the congestion and traffic flow impact of construction projects. These predictive tools are integrated within route planning models of shippers/carriers. We designed practical, scalable tools that use readily available and up to date traffic flow data from ITS operators such as and Michigan Intelligent Transportation Systems (MITS) Center (our collaborators). The flow data is used to estimate OD matrices at the source/sink nodes of the network under consideration. Given the transportation improvement project scope and extent/corridor, we use estimated OD matrices for estimation of the future state of network traffic flows through equilibrium / traffic assignment models. The methods are designed for seamless integration into existing JIT freight planning models/tools.
