Abstract:There are over 15,000 centerline miles of highways in the state of California with Caltrans Division of Maintenance performing upkeep operations for the roadways and the accompanying roadside features, including items such as guardrails, signs, landscaping, storm water management systems, and traffic signals. Experienced maintenance workers who have detailed knowledge of their home base roadways have accumulated a wealth of knowledge on the pros and cons of the design and implementation of roadside features of all types. In an effort to improve the safety and the work conditions of maintenance workers, meetings with these roadway experts throughout the state were conducted to capture their ideas on how to improve the design and implementation of roadside features. The objective of this research was to identify critical roadside features that have recurring maintenance needs or those whose maintenance would expose workers to high-risk environments, such as those within 30 feet of high-speed traffic. This research study has identified such critical roadside features and have made recommendations on the need for policy change, or for additional training, or for further research. Such additional research can include life cycle analyses methods considering maintenance resources and worker’s time exposure to traffic. The benefits of this research study includes providing support for potential policy change to emphasize maintainability with the goal of increased worker safety as well as recommendations for updates and additions to the Highway Design and Maintenance Manuals and Training that can have positive impacts on worker safety.
