NCHRP Project 3-80 was initiated to develop guidance on the effective use of traffic enforcement strategies in highway work zones. Traffic enforcement is viewed by many as one of the most effective means available for reducing speeding and other undesirable driving behaviors that compromise safety in a highway work zone. However, practices nationally vary widely on the enforcement strategies and philosophies used in work zones, the administrative mechanisms applied to establish and maintain a work zone enforcement program, payment methods for work zone enforcement efforts, techniques applied to supplement work zone enforcement, and public information dissemination practices employed to support work zone enforcement in a region. In this report, results are described of three research efforts performed to facilitate the development of guidance on this topic: 1) determination of whether driver opinions, perceptions, and behaviors related to the risk of violating traffic laws in work zones differ depending on whether work zone enforcement practices in a region are predominantly passive (positioned in the work zone with lights flashing to attract attention and reduce speeds) or active (pursuit of violators and issuance of citations); 2) determination of the effects of using an enforcement officer and vehicle in a traffic-calming (passive enforcement) mode upstream of work zones where traffic queues develop on the speed, deceleration, and erratic maneuvers of traffic approaching the traffic queue; and 3) a generalized economic analysis of the potential crash cost reductions associated with the provision of enforcement in work zones was undertaken to determine AADT thresholds at which the benefits of providing enforcement in work zones exceeds the costs of enforcement. With respect to the first point, these studies indicate that the use of passive enforcement does not significant degrade driver perceptions of enforcement or driver response to enforcement compared to active enforcement use. Next, studies of enforcement upstream of work zone traffic queues were somewhat inconclusive, and did not indicate a clear effect of having enforcement deployed in this manner. Finally, the analysis of work zone crash costs suggests that enforcement safety benefits outweigh the costs of deployment in daytime work zones on roadways exceeding 5000 to 20,000 vehicles per day (depending on hourly enforcement costs), and at nighttime work zones on roadways exceeding 20,000 to 65,000 vehicles per day.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 746: Traffic Enforcement Strategies for Work Zones presents guidance for the safe and effective deployment of traffic enforcement strategies in work zones on high-speed highways (those with speed limits of 45 mph or greater). The report discusses the planning, design, and operation of traffic enforcement strategies, as well as administrative issues that should be considered. The contractor's final report providing background information for the project that produced NCHRP Report 746 was published as NCHRP Web-Only Document 194: Traffic Law Enforcement in Work Zones: Phase II Research.

Transportation agencies across the U.S. are expending a great deal of effort to improve highway work zone safety. Among those efforts is a special fund for work zone enforcement established by the Indiana Department of Transportation (INDOT). The allocation of enforcement funding was based on expert knowledge and weights and scores applied to work zone characteristics considered relevant to traffic safety. The objective of the reported project was to develop a rational and defendable tool for programming police enforcement that maximizes the safety benefits of police enforcement in INDOT work zones. To understand what affects work zone safety, the research team carried out an extensive literature review, designed field experiments to evaluate the effect of selected enforcement strategies on drivers' behavior in work zones, and developed speed models incorporating the effect of police enforcement. The estimated speeds were used to derive CMFs that express the effect of the police enforcement strategy on work zone safety. Finally, the research team combined all of the developed components in a method of predicting the costs and the safety benefits in works zones under various enforcement strategies. This last method was included in the optimization tool for programming police enforcement in a group of planned work zones. The described project developed an optimization tool implemented in a Microsoft Excel spreadsheet with the OpenSolver add-in. The tool is flexible, straightforward, and easy to use. The user should be able to quickly become familiar with the required input, results, and obtained solution.

This synthesis documents information regarding the current state of practice for work zone speed management. The report compiles data, procedures, techniques, and technical issues related to observing and comparing work zone speeds. The speed management measures have been organized into four categories: engineering, operational, enforcement, and public education and outreach. Information included in this study was acquired through a review of the literature, two surveys of state department of transportation representatives in all states, a compilation of state agency public information campaigns, and follow-up interviews with select survey respondents from several U.S. states and one Canadian province.
