of plans that comply with the requirements of both the
Intermodal Surface Transportation Efficiency Act of 1991
and the Clean Air Act Amendments of 1990. The New
York model developed for NYMTC in the period 2000 to
2002 (actual modeling work period, though the data col-
lection and network preparation stages started in 1994) is
the first comprehensive multimodal model developed for
the New York Metropolitan Region, which encompasses
an entire 28-county, three-state region that includes por-
tions of Connecticut and New Jersey, with a total popula-
tion of 20 million residents. The NYMTC model's success
has proven that the concept of a microsimulation activity-
and tour-based model can be applied for a large metropol-
itan area with a unique level of complexity for the
transportation system.
The NYMTC model structure appears in Figure 1. It
has four major consecutive modules:
· Tour generation, which includes household synthe-
sis, automobile ownership, and journey frequency choice
models;
· Tour mode and destination choice, which includes
premode choice, primary destination choice, entire-tour
mode combination choice, stop-frequency choice, and
stop-location choice;
· Time-of-day choice and preassignment processor,
which includes tour time-of-day choice for outbound
and inbound directions, trip mode choice, and construc- FIGURE 1 Structure of NYMTC model (New York).
