Recording for TMIP Webinar - Integrating Exploratory and Simulation Modeling into Regional Transportation Planning

Greetings:

The webinar recording is now available at https://tmip.org/webinars.

Thank you again to the presenters and the particpants.

Session Description

This webinar summarizes findings of a project marrying two emerging areas of transportation research: regional dynamic traffic assignment (DTA) and exploratory modeling and analysis (EMA). EMA enables transportation planners to make better decisions in the face of deep uncertainty about demographic and land use forecasts, uncertainty relating to shifting economic and market factors, and uncertainty surrounding emerging transportation technologies like connected and autonomous vehicles. DTA helps planners estimate the operational impacts of projects with greater fidelity and confidence than static assignments afford.

This project demonstrates the potential benefits of bringing EMA and DTA together to help manage deep uncertainty in the transportation planning context. Caliper Corporation has completed integration of TMIP’s EMA Tool (EMAT) with three core models of the Las Vegas Metropolitan area. These models include travel demand and DTA models maintained by the Regional Transportation Commission for Southern Nevada (RTCSNV). Two DTA models were integrated with EMAT: one based on microsimulation and suitable for analysis of traffic operations and another based on mesoscopic simulation and designed for planning-level decision-making. EMA experiments were performed, and results and lessons learned will be presented.
