COMPASS©
Demand Forecasting System
This software is a comprehensive strategic policy planning tool
to assist rail, highway, air, and transit management in planning
their systems.
COMPASS©
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.
The COMPASS©
model consists of a three-step analysis process that
estimates:
Total market growth by all modes and purposes
of travel
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.
COMPASS©
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.
