Traffic Diversion & Safety Drawing

Traffic diversion is a crucial component of road construction and maintenance projects. It involves redirecting traffic from its usual path to ensure the safety of both workers and road users. Proper traffic diversion plans are essential to minimize disruptions and maintain smooth traffic flow.

Key Components of Traffic Diversion:

  • Planning and Approval:
    Before implementing any traffic diversion, a detailed plan must be prepared and approved by relevant authorities. This plan includes the proposed diversion routes, duration, and necessary safety measures.
  • Signage and Barriers:
    Clear and visible signage is crucial to guide drivers through the diversion. This includes warning signs, directional signs, and speed limit signs. Barriers such as lightweight movable plastic barriers, concrete barriers, and traffic cones are used to delineate the diversion path.
  • Safety Measures:
     Safety is paramount in traffic diversion. Measures include the use of arrow flashers powered by solar energy, temporary signage, and crash cushions at the end terminals of barriers. These measures ensure that both the workers and the road users are protected.
  • Traffic Management:
    A traffic management officer is responsible for overseeing the diversion. Their duties include ensuring all signage is in place and in good condition, obtaining necessary permits, and coordinating with local authorities.

Traffic Diversion & Safety Drawing

  • Communication:
    Effective communication with the public is essential. Informing road users about the diversion through various channels helps in reducing confusion and ensuring compliance with the new traffic arrangements.
  • Safety Drawing:
    Safety drawing is a detailed schematic representation of the traffic diversion plan. It includes all the necessary elements to ensure the safety and efficiency of the diversion.
  • Detailed Layout:
    The safety drawing provides a detailed layout of the diversion route, including the placement of barriers, signage, and other safety equipment. It is signed and stamped by the contractor, consultant, and client to ensure accountability.
  • Compliance with Standards:
    The drawing must comply with local authority requirements and safety standards. This includes the use of standard end terminals or crash cushions for long-duration diversions.
  • Regular Updates:
    The safety drawing should be regularly updated to reflect any changes in the diversion plan. This ensures that the plan remains effective and safe throughout the duration of the project.

Examples of Traffic Diversion

  • Lane Closures:
    Single Lane Closure:
    Used when work is being done on one side of the road. Traffic is diverted to the remaining open lane, often controlled by temporary traffic signals or flaggers.
    Multi-Lane Closure:
    Involves closing multiple lanes on a multi-lane road. Traffic is diverted to the remaining open lanes, with clear signage and barriers to guide drivers.
  • Detours:
    Short-Term Detours: Implemented for brief periods, such as during emergency repairs. Drivers are directed to alternate routes using temporary signs and barriers.
    Long-Term Detours:
     Used for extended projects, such as major road reconstructions. Detailed detour plans are developed, including clear signage and communication with the public about the changes.
  • Contraflow:
    Contraflow Lane:
     A lane on the opposite side of the road is used to carry traffic in the opposite direction. This is often used on highways where one side is closed for construction, and traffic is diverted to the other side with barriers separating the opposing flows.

Examples of Traffic Diversion

  • Temporary Roundabouts:
    Mini-Roundabouts:
     Installed at intersections to manage traffic flow during construction. These are smaller and easier to set up than permanent roundabouts and help maintain smooth traffic movement.
  • Chicanes and Realigned Intersections:
    Chicanes: These are artificial turns or curves added to a road to slow down traffic. They are often used in residential areas during construction to ensure safety.
    Realigned Intersections:
     Temporary changes to intersection layouts to accommodate construction work. This might involve shifting lanes or creating new temporary intersections.
  • Use of Barriers and Signage:
    Concrete Barriers:
     Used to separate traffic from construction zones, ensuring safety for both workers and drivers.
    Plastic Barriers and Cones:
     Lightweight and movable, these are used to guide traffic through temporary lanes and detours.
    Signage:
     Clear and visible signs are essential to inform drivers of upcoming changes, speed limits, and directions.
