Abstract

Operating a high occupancy vehicles (HOV) lane within a relatively narrow roadway has the potential for a total blockage of the roadway when an accident occurs. This fact places special requirements on the information system for operation of the HOV facilities. This report combines the finding of other phases of this research with the special requirements of HOV facilities and recommends dectector placement than will effectively meet HOV lane operational needs. The recommendations include the use of multi-conductor cable to form the loop when induction loop detections are used for speed measurement, the use of 9 meter (30 foot) spacing between loops at the monitoring station and the placement of wrong-way movement detectors on the entry roadways at the HOV lane interchanges. A spacing for mainline monitoring stations at about 800 meters (2500 feet) and wrong-way detectors on the entry roadways are recommended. (A)
