MAJOR URBAN CORRIDOR FACILITIES: A NEW CONCEPT

There have been numerous approaches to the growing problem of urban highway congestion. These have ranged from the relatively inexpensive traffic engineering treatments of facilities already in existence, to proposals for massive new public works projects requiring large amounts of money. Because of the high costs associated with full freeway and grade-separated rapid transit projects, the possibilities for intermediate types of solutions should be reexamined where urban geographic, topographic, traffic concentration, and trip-length conditions may have some practical advantages over other facility types. This paper considers intermediate transit solutions to urban traffic congestion, with a focus on new, fast, large, 3-sectioned articulated transit vehicle operations termed limited tramlines. This concept is explained and discussed in detail.
