Abstract:There is a need to develop new policies and practices for roadside features that support the California Department of Transportation’s (Caltrans’) safety and asset management goals. The goal is to assist highway designers in including maintenance planning strategies to improve worker safety and working conditions. Such policies and practices should be defensible and based on data and scientific methodologies and techniques. The recent research project “Performance Measures for Roadside Features” (Task 2761) identified a number of items, such as including more hardscape, that would enhance worker safety if fully implemented. Caltrans needs research to prioritize these items and to create draft guidance (such as the memos in the appendices) that would provide templates for the Divisions of Maintenance and Design to use to update the Maintenance Manual and the Highway Design Manual and thus realize these safety benefits. Researchers from the Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center at UC Davis revisited previous findings to develop a prioritized list of items that could enhance worker safety. Using this prioritization, the researchers drafted guidance that could be used by Caltrans Maintenance or Design as templates (draft engineering memos) for updating the appropriate manuals. This report documents the research effort and findings. The memos generated through this research are provided in the appendices.
