Typically they involve automatic operation with rubber tyre guidance; rail systems which are clearly superior are concurrently ignored. Dr. Vukan R. Vuchic of the University of Pennsylvania and Richard M. Stanger of the Metropolitan Atlanta Rapid Transit Authority* urge transit planners, operators and equipment manufacturers to exploit the great potential of rail technology rather than pursuing innovation for its own sake.flash_audioEngineeringSystems EngineeringTransportation EngineeringArticle
