Transit Demand Model

Interwest GIS provides transit demand modeling for public agencies. For Shasta Regional Transportation Agency (SRTA), Interwest used the ArcGIS-integrated planning tool called Transit Boarding and Estimation Simulation Tool (TBEST).

Examining Ridership 
The validated model is visual and interactive, with tools for examining ridership forecasts based on socioeconomic, land use, and transit network builds for the service area.

• Captures the current socioeconomic and land use conditions for a service area
• Codes these conditions within a transit network
• Determines stop-level ridership
• User creates scenarios to determine potential impact on future ridership

Ridership Projections 

Intewest GIS used TBEST and GIS to project ridership under different scenarios including:

• Adding a new Route
• Re-routing an existing route 
• Adding Sunday Service
• Increasing fares
