1 Selection and location

The first step in managing the lifecycle of roadside barriers is to select the appropriate type and location for each site. There are different types of barriers, such as concrete, metal, or cable, each with its own advantages and disadvantages. The location of the barriers depends on factors such as traffic volume, speed, curvature, slope, and roadside hazards. You should follow the design standards and guidelines for your jurisdiction, and use tools such as crash data analysis, benefit-cost analysis, and simulation models to help you make informed decisions.

2 Inspection and evaluation

The second step in managing the lifecycle of roadside barriers is to inspect and evaluate their condition regularly. You should conduct routine inspections at least once a year, or more frequently if there are signs of damage or deterioration. You should also inspect the barriers after any crashes or severe weather events that may have affected their integrity. You should use a standardized inspection form and rating system to record the type, extent, and severity of any defects or damages. You should also document any changes in the roadside environment that may affect the performance of the barriers.

3 Repair or replacement

The third step in managing the lifecycle of roadside barriers is to plan and implement repair or replacement strategies based on the inspection and evaluation results. You should prioritize the repairs or replacements according to the risk and urgency of each situation. You should also consider the availability of resources, such as materials, equipment, and personnel, and the potential impact on traffic flow and safety. You should follow the best practices and specifications for repairing or replacing the barriers, and ensure that the quality and functionality of the barriers are restored.

4 Performance and testing

The fourth step in managing the lifecycle of roadside barriers is to monitor and measure their performance and testing results. You should collect and analyze data on the frequency, severity, and outcomes of crashes involving the barriers, and compare them with the expected or desired performance levels. You should also conduct periodic testing of the barriers, either in the field or in the laboratory, to verify their structural and operational characteristics. You should use the performance and testing data to evaluate the effectiveness and efficiency of the barriers, and to identify any areas for improvement or innovation.

5 Maintenance and management

The fifth step in managing the lifecycle of roadside barriers is to establish and follow a maintenance and management plan that covers all aspects of the barrier lifecycle. You should define the roles and responsibilities of the various stakeholders involved in the barrier lifecycle, such as designers, contractors, inspectors, operators, and owners. You should also establish the policies and procedures for the maintenance and management activities, such as inspection, repair, replacement, performance, testing, and reporting. You should also allocate the necessary budget and resources for the maintenance and management plan, and review and update it regularly.

6 Benefits and challenges

The sixth and final step in managing the lifecycle of roadside barriers is to recognize the benefits and challenges of doing so. The benefits of managing the lifecycle of roadside barriers include enhancing the safety and mobility of highway users, reducing the costs and liabilities of crashes and damages, and extending the service life and value of the barriers. The challenges of managing the lifecycle of roadside barriers include complying with the changing standards and regulations, coordinating with the multiple stakeholders and agencies, and adapting to the evolving technologies and practices.
