Summary
The *Service Patrol Handbook*, published by the Federal Highway Administration (FHWA) in 2008, addresses the need for standardized, effective traffic incident management strategies to reduce highway congestion. The document is motivated by the significant impact of traffic incidents, which account for approximately 25 percent of total congestion and cause disproportionate delays; for instance, blocking one of three lanes reduces traffic flow by 50 percent. The FHWA aims to assist state departments of transportation (DOTs) and metropolitan jurisdictions in establishing or upgrading service patrols to "Full-Function Service Patrol" (FFSP) standards. This initiative supports the U.S. Department of Transportation’s National Strategy to Reduce Congestion and the National Traffic Incident Management Coalition’s goals for improving safety, travel time reliability, and incident clearance efficiency. The handbook was developed through a high-level literature search and telephone interviews with 24 existing U.S. service patrol programs to assess current practices and identify operational constraints. The authors analyzed data regarding program history, service types, equipment, personnel, and funding models. The document synthesizes this information to define the desired characteristics of an FFSP, providing guidelines on operational policies, vehicle specifications, training requirements, and integration with regional traffic management centers (TMCs). It also examines the variability in current programs, noting that while many patrols focus on motorist assistance during peak hours, capabilities range widely from basic aid to complex incident response involving hazardous materials and emergency traffic control. Key findings highlight the benefits of service patrols, including reduced incident duration, quicker debris removal, and improved safety for motorists and responders. The handbook identifies that effective FFSPs should operate 24 hours a day, seven days a week, and provide comprehensive services such as vehicle recovery, minor repairs, fuel provision, first aid, and emergency traffic control. It notes that current programs often lack consistency in operational hours, equipment, and training, with many limiting service to rush hours despite high crash rates during nighttime and weekends. The document also details various funding mechanisms, including public-private partnerships and contract services, while acknowledging limitations such as budget constraints and staffing challenges. Specific examples illustrate how different jurisdictions, such as Florida’s Road Rangers and Minnesota’s FIRST program, implement specialized services like defibrillator use or chainsaw operation. The significance of this handbook lies in its provision of a unified framework for standardizing service patrol operations across the United States. By defining the components of a Full-Function Service Patrol, the FHWA seeks to ensure consistency in driver expectations and responder capabilities. The guidelines aim to help agencies optimize resource allocation, enhance coordination with emergency services, and maximize the congestion-reduction benefits of service patrols. Ultimately, the document serves as a strategic tool for DOT decision-makers to implement robust incident management programs that improve highway mobility, safety, and operational efficiency.
Key finding
The document provides guidelines and rules of thumb for implementing Full-Function Service Patrol programs rather than reporting empirical research results.
