In an effort to increase the carrying capacity of urban freeways, two Transportation System Management (TSM) measures have received emphasis--high occupancy vehicle (HOV) lanes and ramp metering with and without HOV bypasses. 'HOV lanes' involve reserving one or more freeway lanes for special use by high occupancy vehicles (buses and carpools) at least during peak traffic periods. The principal objectives of this research were: (1) To determine the relative effectiveness of reserved freeway HOV lanes and ramp metering with and without HOV bypass lanes, in improving highway efficiency; (2) To identify the characteristics, circumstances and conditions under which each is most effective; (3) To identify problems or issues likely to affect the implementation of HOV lanes or ramp metering; and (4) To present the results in a set of planning considerations which can be utilized by non-technical decision makers, policymakers and planners, particularly with respect to how and when to select an HOV or ramp meter technique.
