Traffic Control Devices And Practices To Improve The Safety Of Mobile And Short Duration Maintenance Operations

Traffic Control Devices and Practices to Improve the Safety of Mobile and Short Duration Maintenance Operations

Improving the Safety of Mobile Lane Closures

TRB's National Cooperative Highway Research Program (NCHRP) Research Results Digests 339: Improving the Safety of Mobile Lane Closures explores practices employed by transportation agencies during mobile lane closures and summarizes research carried out on different components of mobile lane closure. Appendices A through D for NCHRP RRD 339 are available online.

Risk Mitigation Strategies for Operations and Maintenance Activities

The objective of this research was to investigate the application of integrated risk modeling to operations and maintenance activities, specifically moving operations, such as pavement testing, pavement marking, painting, snow removal, shoulder work, mowing, and so forth. The ultimate goal is to reduce the frequency and intensity of loss events (property damage, personal injury, and fatality) during operations and maintenance activities. This report includes a literature review that identifies the current and common practices adopted by different state departments of transportation (DOTs) and other transportation agencies for safe and efficient highway operations and maintenance (O/M) activities. The final appendix to the report includes information for eight innovative O/M risk mitigation technologies/equipment and covers the following for these technologies/equipment: Appropriate conditions for deployment; Performance/effectiveness, depending on hazard/activity; Cost to purchase; Cost to operate and maintain; Availability (resources and references)
