Project objective. Using a micro-simulation modeling of the network, quantify the diversion impacts of separating the I-77/I-81 overlap. 

Project Abstract. VDOT is currently in the process of redesigning the I-77/I-81 overlap. An integral part of the project is to quantify the diversion impacts of separating the I-77/I-81 overlap. In order to evaluate the diversion impacts, a micro-simulation modeling of the network is required. Furthermore, VDOT would like to compare and contrast the capabilities of the FHWA's simulation model CORSIM and the INTEGRATION model. 

Tasks. The project will extend over two years and involves three main tasks. Task 1 involves a detailed comparison of CORSIM and INTEGRATION for the evaluation of stationary bottlenecks. Task 2 involves a validation of INTEGRATION's diversion logic. Finally, Task 3 involves a detailed modeling of the I-77/I-81 overlap. 

Milestones. This project is scheduled to begin in December 2000 and be completed by December 31, 2002. 

Student involvement. Three full-effort GRAs.
