Background

NYMTC has developed the Best Practice Model (BPM) in response to the Federal Requirements of Intermodal Surface Transportation Efficiency Act (ISTEA) and Clean Air Act (CAA) of the 1990s. This model predicts changes in the future travel patterns in response to changes in the demographic profiles and transportation systems in the region. The study area includes 28 counties in New York, New Jersey, and Connecticut. This model was done in phases

Phase 1
The Interim Analyses Model IAM was put in place in 1994 as a workable model with available data. It was not a four step model. The trip tables were synthesized from the trip tables of the various existing models in the region. A straight line highway network was used to run the assignments to meet the conformity regulations.

Phase 2
A household interview survey was conducted in 1996-1997 in the region along with speed, traffic counts, and cordon count data collection. These data were processed and a state of the art model called the Best Practice Model (BPM) was put in place in early 2002. The model is a choice based model and comprises of 3586 transportation analysis zones in the 28 counties. The GIS based highway network contains 52,794 links and includes all minor arterial and higher facility roadways. The transit route system has 1,176 routes and consists of many different types of services including commuter rail, express bus, local bus, subways, ferries, PATH, and aerial tramway.

The BPM will provide the decision makers and the planners of this region with a very valuable tool, for the long range plans, subarea and corridor analysis.
