Demand Forecasting System
This software is a comprehensive strategic policy planning tool
to assist rail, highway, air, and transit management in planning
generates ridership and revenue forecasts for any set of socioeconomic,
network, and competitive mode conditions. Outputs include traffic
forecasts; revenue estimates; and rail, highway, air, and transit
market shares over a given timeframe for a variety of conditions.
model consists of a three-step analysis process that
Total market growth by all modes and purposes
Induced demand due to changes in quality of
service offered by any mode (air, bus, rail, auto)
Modal Split / Route Split model that estimates market or
route shares using a hierarchical mode choice analysis.
A key metric of the COMPASS©
model is "generalized cost." The generalized cost function
allows time, cost frequency, and service attributes to be combined
into a single metric that can show how changes in speed, frequency,
or fare will affect the use and market-share of any mode.
has been used for ridership forecasts of many major transportation-related
projects, including regional multi-modal studies: Midwest Regional
Rail Initiative: Federal Railroad Administration Northeast Corridor
Project; Ontario-Quebec High- Speed Rail Study; Portland-Boston
Intercity Rail Study; Athens-Thesseloniki High-Speed Rail Study;
North-South Rail Link Study, Boston; Channel Tunnel; Florida High-Speed
Rail Study; Cross London Rail Link; and Argentina National Rail
Plan; and Pakistan Mainline Electrification Study.
