million were located in Manhattan, 1.5 million in the rest of New York City, and 2.4 million in the suburban counties of the MTA district. Elsewhere in the Tri-State Region, some 4 million jobs are located in older cities and suburban communities. I, Owing to its superior transit accessibility, the nine-square mile Manhattan CBD, which contains more than one fifth of the Region's total employment, supports a unique concentration of over 600 million square feet of nonresidential and over 200 million square feet of residential floorspace. In excess of three million people enter this area on a daily basis, two-thirds of them by public transit. With employment subcenters located elsewhere in New York City, the City has historically provided more employment opportunities than housed resident labor force. According to the 1990 Census, 515,000 more persons worked in New York City in primary jobs (excluding multiple jobs) than resided in the City as employed workers, while 320,000 more workers resided in suburban portions of the MTA district than were employed outside the City. Over the past decade, the jobs-housing relationship has changed somewhat as worksite employment has grown faster in the suburbs than has the resident labor force, while renewed population growth in New York City has fueled the supply of resident workers. While New York remains the Region's job center, reverse commuting of City residents to suburban jobs and intrasuburban mobility of resident suburban workers have risen. Often destined to dispersed job locations, suburban-bound trips represent challenges to a hub­ bound public transit system.

Organization of the Handbook In the following chapters, this Handbook provides the reader with an exposition of the technical development and configuration of the regional equilibrium and station area models, with Chapter 2 devoted to NYREG and Chapter 3 to NYSTA. In Chapter 4, some issues of value capture are discussed as a framework to regional and station area policy simulations of the models, which are presented in Chapter 5. The final chapter concludes with a description of hardware, software, and training support needs for model implementation. Two appendices contain NYREG methodology in detail.
