3 What Is IDAS? A Tool that: allows the estimation of transportation impacts resulting from ITS deploymentsallows the estimation of transportation impacts resulting from ITS deployments is consistent with current planning analysesis consistent with current planning analyses uses output from existing regional transportation travel demand modelsuses output from existing regional transportation travel demand models determines the transportation impacts of ITSdetermines the transportation impacts of ITS –deployment costs, travel time, safety, emissions, etc. –monetary equivalents

4 Who Is IDAS Designed For? Transportation plannersTransportation planners ITS professionalsITS professionals Systems operators, OthersSystems operators, Others Those who need to assess the costs and benefits of deploying ITS

5 What Do I Need to Use IDAS? Knowledge of Travel Demand ForecastingKnowledge of Travel Demand Forecasting Knowledge of ITSKnowledge of ITS Travel demand model filesTravel demand model files –Node coordinates, network links, matrix data (e.g., trip tables) Alternative ITS deployments for comparisonAlternative ITS deployments for comparison
