Temporary traffic management (TTM) is a critical aspect of ensuring the safety of road users and workers during construction or maintenance work on roads.
TTM involves the use of various traffic control devices, signs, and personnel to guide traffic through work zones safely. This article provides an overview of how TTM works and the key elements of an effective traffic management plan.
Planning and Designing TTM
Before any work can begin, a TTM plan must be developed to ensure that the work zone is set up safely and efficiently.
The TTM plan is developed based on the type of work being done, the duration of the work, and the traffic volumes in the area. A TTM plan typically includes a site layout, traffic control devices, signage, and a plan for managing traffic flow.
Site Layout
The site layout is an essential element of any TTM plan. It outlines the location and layout of the work zone and provides information on the types of traffic control devices and signage that will be used.
The site layout should consider the size and type of vehicles that will be using the road, the speed limit of the road, the location of pedestrian crossings and bike lanes, and the location of nearby intersections and traffic signals.
Traffic Control Devices
Traffic control devices are used to guide traffic through work zones safely. They include cones, barricades, and warning signs. The type and placement of traffic control devices depend on the location and layout of the work zone.
For example, cones may be used to guide traffic around a work zone on a straight stretch of road, while barricades may be used to close a lane on a curved road.
Signage
Signage is an essential element of TTM as it provides information to drivers about the work zone and any changes in traffic patterns.
Signs may include temporary speed limit signs, lane closure signs, and detour signs. The type of signage used will depend on the location and layout of the work zone.
Managing Traffic Flow
Managing traffic flow is a critical element of TTM. It involves controlling the flow of traffic through the work zone and ensuring that road users are aware of any changes in traffic patterns.
Traffic flow can be managed using various strategies, including lane closures, temporary traffic signals, and flag persons.
Implementing TTM
Once the TTM plan has been developed, it is essential to implement it effectively. This involves ensuring that all traffic control devices and signage are set up correctly and that personnel are trained to manage traffic flow through the work zone.
It is also essential to monitor the work zone regularly to ensure that it remains safe and effective.
Conclusion
Temporary Traffic Management is an essential aspect of road construction and maintenance. It involves the use of various traffic control devices, signage, and personnel to guide traffic through work zones safely. Planning and designing TTM are critical to ensuring that the work zone is set up safely and efficiently. Implementing TTM requires careful attention to detail and effective management of traffic flow.
