Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: As traffic-related work zone crashes continue to increase across the nation, safety of road users and workers has become a top priority for transportation agencies. Since inattention and irresponsible behavior by drivers are surmised to contribute to the frequency of work zone crashes, a program featuring extraordinary presence of and enforcement by law officers has been implemented in many states to address this concern. A literature search of such programs and related research was conducted. While the overall benefits of these activities have been found positive, much of the evidence has been anecdotal. To assess the scope of extra work zone enforcement programs, a survey was developed and distributed to state departments of transportation across the nation. This survey sought information regarding these efforts such as criteria for selection of target work zones, methods of enforcement operations, and beneficial results. A special survey was also designed and distributed to enforcement agencies in Iowa and other selected states. In addition to the surveys, personal contacts and office visits were conducted by the research team staff. The study found that use of extra enforcement in work zones is a common practice in many states and these activities appear to be increasing. Current literature, survey responses, and interviews have all indicated a prevalent opinion for the benefits of increased law enforcement presence and activity in work zones. Very few comments offered conclusions of negative impacts, such as additional congestion, from these efforts. However, the beneficial effects of focused enforcement have not been intensively quantified. In addition, procedures for the use of law officers in work zones are quite inconsistent across the nation, as is the general implementation of specific legislation addressing work zone traffic violations. Similar variation can be found in funding levels and sources for enforcement activities in work zones among the states. Training of law officers prior to work zone duty does not appear to be commonly required, though the value of focused training is being recognized in some states. As crashes and deaths continue to rise annually in our nation's work zones, it is imperative that demonstrated beneficial programs such as the expanded use of law officers in these locations be continued, refined, and expanded. Future study is needed to supplement the knowledge base and provide guidance to agencies when considering the use of law enforcement to calm traffic, ensure compliance with traffic laws, and thus provide for safer work zones.

Book excerpt: This report presents the results of research performed to identify and assess the work zone-related legislation that has been implemented in various states nationwide. As of 1997, 42 states had passed legislation pertaining to traffic laws in work zones. The report includes information on the types of legislation that has been passed, implementation characteristics and issues encountered by state transportation agencies, analysis of the effect of the legislation on work zone accidents, and enforcement characteristics and issues encountered pertaining to the legislation.

Available in PDF, EPUB and Kindle. Book excerpt: One of the ways a state department of transportation or other transportation agency can address work zone safety and other impacts is to develop and implement a Transportation Management Plan (TMP). The TRB National Cooperative Highway Research Program's NCHRP Research Report 945: Strategies for Work Zone Transportation Management Plans provides a practitioner-ready guidebook on how to select and implement strategies that improve safety and traffic operations in roadway construction work zones.

This book was released on 2007 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public travel by motor vehicles is often necessary in road and street sections that have been officially closed for construction, repair, and/or other reasons. This authorization is permitted in order to provide access to homes and businesses located beyond the point of closure. The MUTCD does address appropriate use of specific regulatory signs at the entrance to closed sections; however, direct guidance for temporary traffic control measures within these areas is not included but may be needed. Interpretation and enforcement of common practices may vary among transportation agencies. For example, some law enforcement officers in Iowa have indicated a concern regarding enforcement and jurisdiction of traffic laws in these areas because the Code of Iowa only appears to address violations on roadways open to "public travel." Enforcement of traffic laws in closed road sections is desirable to maintain safety for workers and for specifically authorized road users. In addition, occasional unauthorized entry by motor vehicles is experienced in closed road areas causing property damage. Citations beyond simple trespass may be advisable to provide better security for construction sites, reduce economic losses from damage to completed work, and create safer work zones.

Book excerpt: 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.
