Certain specific problem areas in the implementation of a dual-mode transit system guideway indicate a need for close scrutiny of differences between standard highway design technology and dual-mode guideway design. One such area is choice of guideway surface materials and their effect on vehicle-guideway interaction characteristics and performance. Operating environment also imposes restrictions on vehicle performance and system capital expenditure by the need for adequate moisture removal techniques. Guideway intrusiveness and subsequent geometric constraints imposed by urban corridors with high-density land use affect performance and level of service since reduced turn radii in CBD areas affect vehicle speed and maneuverability within ride comfort and safety limits. Emergency operations and vehicle retrieval techniques must be carefully developed to minimize system downtime and maximize safety. Fail-safe principles must also be defined, for their interpretation affects system safety, operating procedures, and capital cost. Solutions to these problems must result in the development of system hardware consistent with dual-mode implementation philosophy.
