Transportation Model What is involved with a travel demand model?

3 Data and Databases Geographic data Network data Attribute data TransCAD model data Socioeconomic data US Census data Jurisdictional boundaries Zip codes Railroads Water Features

4 I-25 Socioeconomic Data Analysis 1998 Data2020 DataLand Use Data

5 Geographic Information Systems A GIS-based transportation model Compatible with other GIS tools Spatial Analysis ArcView Shape Files TransCAD *.dbd Files

6 TransCAD Travel Demand Model Overview Four-step process Model inputs Model results Post processing and analysis

7 Modeling Process Trip Generation Trip Distribution Mode Analysis Traffic Assignment Socioeconomic Data Roadway Network Transit Network Transit Ridership Transit Assignment Roadway Volumes Performance Report How many trips? Where will they go? What mode? What route? Identify needs Alternatives analysis

Model Applications How can TransCAD help YOUR department?

9 Routing and Shortest Path Applications Football games Parades Construction closures Fleet management (e.g., snowplows) Hazardous waste Emergency response

10 Site Selection / Geocoding Fire stations School sites Park locations

11 Development Review Adequate Public Facilities Ordinance Traffic Impact Analysis Directional splits for a proposed development Impact of a development on a specific intersection

12 Travel Sheds / Critical Link Analysis Identify users of a specific facility or intersection

13 Transit Planning and Operations CSU Transportation Planning Transfort Strategic Plan Mason Street Master Plan Market Identification and Productivity Management and Placement of Capital Assets

14 Land Use / Transportation / Air Quality Conceptual level analysis of LUTRAQ relationship City Plan updates Triggers – population vs. VMT growth Air quality and emissions inventory Stationary and mobile sources On-road mobile emissions estimation Mobile5 Nonattainment area Energy and fuel consumption

15 Land Use and TAZ Overlay Land Use Map TAZ Map Land Use and TAZ Overlay

16 Land Use Data Conversion Develop conversion factors for major land use categories Apply factors based on local and regional land use plans for each TAZ Compare results to: Previous estimates Transportation plan estimates
