Modern Concepts in Rapid Transit and the Use of Rubber Tires for Transit Vehicles 640451
A resurgence of interest in rapid transit has resulted in a multiplicity of systems being proposed. Among these have been proposals to use guided rubber tired vehicles. The history and current status of development of a number of these systems is presented. The development of a new supported, dual track rubber tired system is described together with a review of operation and design considerations. Rolling resistance and acoustical factors are discussed and costs of several types of systems are compared. While rubber-tired systems are more costly than those having conventional steel wheels, special consideration of grades and community acceptance may justify their use.
