Circulation plans are used by i.e. by city planners and other officials (such as county planning officials, ...) to manage and monitor traffic and pedestrian patterns in such a way that they might discover how to make future improvements to the system. [1]
The cycle time is the time it takes for a cycle to complete. Some jurisdictions have maximum cycle times. For example, in the UK this is 120 seconds or 90 seconds where pedestrian facilities are present. Under actuated control, the reversion is the stage which the traffic controller will return to if there is no demand. [4]
Safety standards (irrespective of traffic control) are mandated by OSHA as well as state-level occupational safety departments. A construction traffic control company operates in the same basic way as any other construction company. Companies submit a bid for a job, the lowest bid is accepted (except in the case of disadvantaged companies), and ...
Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems.

The Manual on Uniform Traffic Control Devices for Streets and Highways (usually referred to as the Manual on Uniform Traffic Control Devices, abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed ...
There is a connection between traffic density and vehicle velocity: The more vehicles are on a road, the slower their velocity will be. To prevent congestion and to keep traffic flow stable, the number of vehicles entering the control zone has to be smaller or equal to the number of vehicles leaving the zone in the same time.
Second, traffic on a freeway is "free-flowing". All cross-traffic (and left-turning traffic) is relegated to overpasses or underpasses, so that there are no traffic conflicts on the main line of the highway, which must be regulated by traffic lights, stop signs, or other traffic control devices.
Maintenance of traffic (MOT), also known as temporary traffic control or temporary traffic management, [1] is a process of establishing of a work zone, providing related transportation management and temporary traffic control on streets and highways right-of-way. This process does not apply to law enforcement officers.
