Ever since the construction of New York City's elevated railroads and, later, subways, the densely packed office district of Lower Manhattan has been heavily dependent on mass transit. Some 500,000 workers now come into the area daily, and as many as 120,000 more may join them in the next several years as a result of new construction. Obviously, there is an urgent need for reliable trip generation data--particularly with respect to the journey-to-work trip--in the planning of transportation improvements. In order to create a sound data base of journey-to-work trip generation and modal split characteristics, we undertook a survey of four major firms: the more than 8,000 responses represented approximately 22,500 employees. The survey presented a fascinating insight to the clearly unique trip-making patterns of the work trip to Lower Manhattan. (Author abstract)
