- KurzbeschreibungThe question of effective utilization of Special Use <br>Lanes (SULs) is often addressed in terms of persons <br>carried, rather than vehicles carried. However, <br>this triggers a more fundamental question, namely <br>what is the underlying upper limit on HOV throughput <br>(or capacity ), given the factors identified in <br>data analysis within this work? Those factors are <br>to a large extent driven by the OD pattern on the <br>facility, which was always known as important but <br>was not accessible enough to be an <br>explicit prevailing condition . The factors that <br>are investigated in this research are: (1) high <br>volumes on the Adjacent Transfer Lane which prevent <br>access to and from the SUL, (2) barrier-separated <br>SUL lanes which may impede access to desired exit <br>ramps, (3) conflicting flow patterns, and (4) hot <br>spots that develop near ramps and SUL access/egress <br>points. The state-of-the-art in SUL research is <br>advanced in this work by (a) studying the effects of <br>the controlling mechanisms on SUL capacity using an <br>extensive data base from Florida and (b) by <br>developing a mathematical model for a facility with <br>a Special Use Lane.
