Jacobson, E L

The study evaluated various high occupancy vehicle (HOV) lane enforcement techniques on a recently constructed section of HOV lanes along I-405 in the Seattle, Washington, area. The research included a related public opinion survey concerning HOV lanes. The enforcement techniques that were evaluated included intensive (or continuous saturation) enforcement, once a week saturation enforcement, and once a week stationary enforcement. The study concluded that each type of enforcement effort helped in lowering the number of HOV lane violations; however, it was not possible to determine which method was most effective. Violations decreased considerably during the first weeks of enforcement, regardless of the type of enforcement. The research team recommends intensive enforcement only for the first three months (or less) of the operation of a new HOV facility. After that point, the level of effort should revert to routine enforcement. The study also makes recommendations concerning the design of HOV lanes related to enforcement issues. Specifically, enforcement areas alongside HOV lanes must be designed in cooperation with the appropriate enforcement agency. Two types of enforcement areas along freeways are suggested.
