Feasibility Study of Advanced Technology HOV Systems. Volume 4. Implementation ofLateral Control Systems in Transitways

摘要

Lateral guidance/control technologies are emerging advanced technologies that canbe deployed independently to enhance traffic operation and safety. They can also be deployed in conjunction with longitudinal control systems to increase capacity of the transportation network. These capacity increases can occur because the use of lateral control may lead to reductions in the lane width requirement, which in turn allows additional lanes to be created within existing right-of-ways. This study investigates some issues concerning the implementation and impacts of lateral guidance/control systems. It proposes phased implementation of these systems, initially in exclusive-access high-occupancy-vehicle (HOV) lanes. The rationale for focusing on these HOV lanes now is that implementation in such systems is likely to be less complex than that on multiple-lane freeways, and the implementation in HOV facilities appears to have its own merit from a policy standpoint.
