Abstract

A traffic engineering project which reversed a lane of the Queens Midtown Tunnel which successfully unclogged traffic in East Midtown Manhattan and resulted in free flowing traffic even in the evening rush hours is described. Details are given of the investigation that led to the development of the scheme. The number of vehicles in motion (VIM) in the central business district (CBD) was derived using a set of equations and data gathered in 1980. VIM was then used to assess a proposal for the introduction of 6000 limousines into the CBD traffic. VIM can also be used to study the number of taxis in motion (TIM). The role of taxis in contributing to congestion and the impact of congestion on taxi productivity could also be studied.
