Aspects of construction and operation of an effective dual- mode transit system (DMTS) are considered in this paper. A general network geometry model is suggested for guideway configurations. A preliminary result suggests that the CBD guideway might best be a rectangular form. Off-guideway zoning, based on a modified Manhattan distance approach, provides possible zones with a theoretically minimal distance for vehicle dispatching. The present concept of medium-sized vehicles and liberal headways has reduced the degree of complexity of network control problems. However, future research in controls should concentrate on areas unique to dual-mode chanracteristics. There is a need for selecting a DMTS network configuration according to an optimal geometry to provide a system with minimum cost. Some methods that can be used to initate such a study are suggested. However, physical constraints, such as land use and engineering, may yet dominate any changes in the network geometry. As for the command and control of DMTS, this paper emphasizes that future reserach should be directed toward topics that are particularly significant to the dual-mode characteristics, both in vehicular control and demand-responsive applications. /Author/
