ITS Deployment Analysis System (IDAS) Gene M. Mc. Hale Federal Highway Administration ITS America Annual Meeting, Boston, May 2000
Outline - IDAS • • • Uses and Capabilities How it Works Where to Get it Where to Get Support and Training Future Plans 2
What Is IDAS? A Tool that: • allows the estimation of transportation impacts resulting from ITS deployments • is consistent with current planning analyses • uses output from existing regional transportation travel demand models • determines the transportation impacts of ITS – deployment costs, travel time, safety, emissions, etc. – monetary equivalents 3
Who Is IDAS Designed For? • Transportation planners • ITS professionals • Systems operators, Others Those who need to assess the costs and benefits of deploying ITS 4
What Do I Need to Use IDAS? • Knowledge of Travel Demand Forecasting • Knowledge of ITS • Travel demand model files – Node coordinates, network links, matrix data (e. g. , trip tables) • Alternative ITS deployments for comparison 5
Travel Demand Forecasting Overview – 4 -Step Approach • • Trip Generation Trip Distribution Mode Choice Traffic Assignment 6
