The use of simulation as an integral element of transit facility design has become increasinglypopular with the development of new software in a transportation engineer’s toolbox. Beyond themost basic operational assessments, these tools have the ability to demonstrate peoplemovements, frequently traveled paths, and separately, levels of service. Of particular interest toarchitects and designers, the simulations provide improved and, at times, more realistic resultsthat better clarify and illustrate the “effectiveness” of their work in a dynamic manner.Furthermore, gone are the days of only relying on spreadsheets and bringing to the public a fewrudimentary tables listing analysis results. It is now commonplace for public interest groups tofrequently expect consultants to have such a dynamic graphical tool at the ready for them toexamine.STV is involved in a number of projects that require input as to how transportation terminals andstations will function well before design alternatives have been finalized. In fact, the provisionfor simulation efforts has been a required evaluation criterion for the acceptance of specificconceptual and preliminary design schemes.Given today’s heighten security concerns, accounting for rapid emergency egress is ofparamount interest to designers. Pedestrian simulation modeling allows for the relatively quickanalysis of multiple pedestrian scenarios including emergency evacuation and normal circulationpossibilities, which realistically assigns people to the nearest exits, measures egress times,identifies points of congestion, and requires minimum preparation time.The capabilities and advantages of pedestrian simulation modeling will be demonstrated basedon analyses performed for projects such as the design of the Port Authority of New York andNew Jersey’s World Trade Center Transportation Hub and the reconstruction of New York CityTransit’s Cortlandt Street 1 Train station within WTC Site. Both projects are intermodal innature, and involve the complex “mixing” of people from many origins and destinations.The images and videos provided by the simulation, and included with this paper, have proven toserve as powerful and conclusive input to designs that provide for the smooth and efficientmovement of people through stations and terminals.
