The goal of this research is to mitigate the risk of highway accidents (crashes) and fatalities in work zones. The approach of this research has been to address the mitigation of work zone crashes through the creation of a formal risk management model to be utilized during the construction management and administration of highway projects for all stages of the project life-cycle. The result of these efforts is realized through the design of an integrated risk management model. A standard risk management model has three components: risk identification, risk analysis, and risk response. The risks are identified by the factors that contribute to work zone crashes. The risk analysis involves understanding the tendency of a hazard to influence the frequency or severity of a loss, and the risk response relates to the appropriate countermeasures to the factors that contribute to work zone crashes. The number of hazards and mitigation strategies corresponding to work zone crashes can be substantial. The intent of this research is to develop a formalized risk management plan to identify potential hazards on plans, designs, or job sites and to cue a risk response to the hazards. Mitigation strategies may take the form of a mitigation "method" (alert motorist, assist worker/motorist, control motorist, inform motorist, and protect worker/motorist). The results of this research will be a formal step-by-step methodology to be utilized by managers and decision makers. Each stage of the project life-cycle (or Project Development Process) will provide a checklist of hazards and mitigation strategies. This research will also provide a qualitative method to assess the likelihood and severity of a hazard or multiple hazards on a roadway work zone. This research is intended to provide a holistic approach to risk management that is to be integrated into the existing corporate structure and not to be considered a standalone program. This integrated approach will allow a formalized procedure to be utilized by any member of an organization during all phases of the construction project life-cycle.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 413: Techniques for Effective Highway Construction Projects in Congested Urban Areas explores a diverse set of techniques designed to address highway construction challenges in congested urban areas such as high-traffic volumes, utility conflicts, complex right-of-way acquisition issues, a diverse stakeholder base, and watchful news media. The report includes four case studies designed to help illustrate effective construction practices in congested urban areas.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 293: Reducing and Mitigating Impacts of Lane Occupancy During Construction and Maintenance describes the current state of the practice for reducing and mitigating the impacts of lane occupancy during construction and maintenance.
This synthesis presents a review of the current practices associated with the techniques and policies employed by state and local transportation agencies to address the many project development issues required for the reconstruction of existing urban and suburban freeways and expressways. This topic is of special interest because there is a need to reconstruct many highway facilities that have been in existence for over 40 years. The need arises both from the deterioration of the infrastructure and from changes in capacity requirements. This synthesis will be of interest to state and local highway design engineers, traffic engineers, finance and contracting specialists, and contracting personnel in these agencies. It will also be of interest to consultants who are engaged in freeway/expressway reconstruction projects. While many of the project development methodologies in practice for reconstruction of urban and suburban freeways and expressways are similar to those used for new construction, there are unique differences that apply primarily to the reconstruction of major urban highway facilities. This report of the Transportation Research Board highlights the similarities and differences in the planning and management of projects as well as in contracting and financing innovations. Methods for effectively managing traffic during the reconstruction process are important to the process, as are traffic control procedures in the work zone. Public participation and public information dissemination related to traffic changes are vitally important to the effective completion of a reconstruction project. Other aspects, such as the design process, including the use of 3-D and 4-D visualization, pavement renewal procedures, environmental impact mitigation and enhancement activities, that are considered in the process are also addressed.
This Work Zone Best Practices Guidebook provides an easily accessible compilation of work zone operations practices used and recommended by various States and localities around the country. The Guidebook is a reference document that can be updated with new approaches, technologies, and practices for effectively managing work zones and reducing the impacts of work zones on mobility and safety as they are identified. The best practices are descriptive, not prescriptive. They describe approaches that have been successfully used by transportation agencies, along with contact information to find out more from the agency using the practice. Each organization must determine which of these practices are best suited for its particular situation, considering all the site-specific factors that affect work zone operations.
