Standards and Regulations Considered in the Review Process

Standards and Regulations in the Traffic Control Plan Review Process


The review process of traffic control plans is a meticulous and critical step in ensuring the safety and compliance of roadwork and construction projects. To achieve these objectives, various standards and regulations are considered during the review. In this article, we will explore the key standards and regulations that play a vital role in this process, covering local, state, and federal guidelines.

1. Local Regulations

Local regulations are the foundation of traffic control plan reviews, as they govern the specific requirements within a municipality or jurisdiction. These regulations may include zoning ordinances, traffic management guidelines, and permit requirements. Local authorities ensure that traffic control plans adhere to these regulations, ensuring the safety and welfare of the local community. These regulations often dictate matters such as signage placement, lane closures, and pedestrian access.

2. State Department of Transportation (DOT) Standards

Each state has its own Department of Transportation, which establishes comprehensive standards and guidelines for transportation projects within its jurisdiction. These standards cover a wide range of aspects, including road design, traffic management, and construction practices. For example, state DOTs often publish manuals that serve as primary references for traffic control plan reviews. These manuals include detailed instructions on sign design, signal phasing, work zone layout, and temporary traffic management.

3. Federal Highway Administration (FHWA) Regulations

When federal funding is involved or projects occur on federally designated highways, the FHWA’s regulations come into play. The FHWA provides oversight and guidance to ensure that projects adhere to federal safety standards and regulations. The Manual on Uniform Traffic Control Devices (MUTCD), a publication by the FHWA, is a critical reference for traffic control plan reviews at the federal level. It sets the standard for traffic control devices, signage, pavement markings, and traffic signal design.

4. American Association of State Highway and Transportation Officials (AASHTO) Guidelines

The AASHTO is a nonprofit organization that develops and publishes transportation-related standards and guidelines, often adopted by state DOTs. AASHTO’s publications, such as the “A Policy on Geometric Design of Highways and Streets” (the “Green Book”), provide essential guidance for road design and traffic control. Traffic control plan reviewers may refer to AASHTO’s resources to ensure that projects align with industry best practices and safety standards.

5. Occupational Safety and Health Administration (OSHA) Regulations

Worker safety is paramount in construction and roadwork zones. OSHA sets stringent regulations to protect workers from potential hazards. Traffic control plan reviews assess whether the plans provide adequate protection for workers as per OSHA’s requirements. This includes evaluating the placement of barriers, barricades, personal protective equipment (PPE) usage, and the identification of work zones.

6. Americans with Disabilities Act (ADA) Accessibility Guidelines

Ensuring accessibility for individuals with disabilities is a critical aspect of traffic control plan reviews. The ADA Accessibility Guidelines specify requirements for accessible pedestrian facilities, including curb ramps, crosswalks, pedestrian signals, and detectable warning surfaces. Reviewers verify that traffic control plans incorporate these guidelines to provide safe and accessible pathways for all pedestrians.

7. Environmental Regulations

Environmental considerations are increasingly important in modern transportation projects. Agencies conducting traffic control plan reviews assess whether projects align with environmental regulations. This includes evaluating potential impacts on air quality, water quality, wildlife habitats, and noise levels. Compliance with these regulations is essential to minimize adverse environmental effects.

8. International Standards

In some cases, projects may involve international standards, particularly when roadways cross national borders. International agreements, such as the Vienna Convention on Road Signs and Signals, provide standardized road signs and signals for participating countries, promoting consistency in traffic control measures.


The review process of traffic control plans relies on a robust framework of standards and regulations at the local, state, federal, and international levels. These guidelines ensure that projects prioritize safety, compliance, and best practices in roadwork and construction zones. The careful consideration of these standards and regulations by reviewers is instrumental in creating effective traffic control plans that safeguard the well-being of all road users and workers while minimizing disruptions to daily transportation.
