Project objective. To calibrate the Integration traffic model to the I-66 corridor in Northern Virginia, and then to apply it for planning purposes, with the objective of showing the value of ITS.

Project abstract. This research will examine scenarios using the INTEGRATION model and perform an extensive sensitivity analysis exploring varying weather conditions, special events, etc.. Four scenarios will be developed: Baseline (1999), No ITS (1999), ITS existing trend in investment (2010), ITS aggressive investment (2010). The research will include a review of how to optimize the phasing-in of ITS projects, and will place particular emphasis on modeling off-peak hours. A considerable effort will be required to collect data on the location, intensity, and emergency response to incidents in this region.

Tasks. 1) Calibrate and validate the model. 2) Prepare scenarios for analysis. Task 3. Conduct sensitivity analyses to ascertain the impact of various planning and operating policies on various scenarios.

Milestones. Dec. 31, 2000, complete calibration and validation. June 30, 2001, complete scenarios. June 30, 2002, complete sensitivity analyses.

Student involvement. One GRA is working full effort (half-time) throughout the project.

Relationship to other research projects. No immediate relationship.

Technology transfer. Calibrated model will be available to researchers and practitioners.

Potential benefits. Much-improved ability of VDOT to plan ITS investment and operations along I-66 corridor.
