Assessment of Traffic Signal Maintenance and Operations Needs at Virginia Department of Transportation
Budgeting for the maintenance and operations (M&O) of traffic signal assets can be done in many ways. Systematic, data-driven approaches are applied to various extents in transportation agencies. However, little has been documented regarding signal resource allocation practices. A traffic signal needs assessment framework recently developed by the Virginia Department of Transportation to support signal M&O funding allocation is presented. The framework offers the potential for incorporating several performance measures into the needs assessment process, including mean time between failures, mean time to repair, average signal component service life, average remaining service life, and share of preventive maintenance costs with respect to overall maintenance costs. Through adjustment of related parameters, the needs assessment framework allows users to set performance targets against key signal system performance measures and compare needs for meeting various performance scenarios.
