• Abstract:
  Highway construction and maintenance work is one of the most hazardous occupations in the United States. In 2018, more than 7,000 work-zone collisions occurred on California roadways, about 2,300 resulting in injuries, and 46 involving fatalities. This research helped move toward reducing those numbers. The California Department of Transportation (Caltrans) needs operational performance metrics that can be used to evaluate the safety risks to highway workers in planning and scheduling of maintenance operations. This research project developed a maintenance task analysis and safety index tool that can be used by the Division of Maintenance for planning of their maintenance work activities. The tool is based on index of difficulty and collision risks to the maintenance workers. The goal of this research was to develop a tool that will help Caltrans achieve its Priorities and Department Goals by improving the safety and efficiency of its highway maintenance activities by providing detailed data that can be used to plan lane closures, time duration of operation, and consider other factors. The tool allows for planning that would improve the safety of highway workers and traveling public. The tool facilitates calculation of maintenance task difficulty and collision risk indices, supporting maintenance planning and scheduling. The tool supports easier identification and input of the most pertinent parameters to determine difficulty and collision risk index. Caltrans can then use objective data and measures for decision-making in planning and scheduling a maintenance operation. The tool is particularly useful in prioritizing multiple operations and selecting operations based on lower difficulty and/or collision risk. The results can also be used in allocating resources in terms of personnel and equipment, considering additional safety measures, and deciding if and what type of lane closure is necessary to reduce the risk of collision and injury potential to personnel and roadside workers. This report documents the tool development and the related research.
