A junction for road vehicles and pedestrians controlled by traffic lights in the UK. The various vehicle and pedestrian movements are separated in either time or space for safety and efficiency. The normal function of traffic lights requires more than sight control and coordination to ensure that traffic and pedestrians move as smoothly, and ...
Road traffic control involves directing vehicular and pedestrian traffic around a construction zone, accident or other road disruption, thus ensuring the safety of emergency response teams, construction workers and the general public. Traffic control also includes the use of CCTV and other means of monitoring traffic by local or state roadways ...
Road traffic control device. Road traffic control devices are markers, signs and signal devices used to inform, guide and control traffic, including pedestrians, motor vehicle drivers and bicyclists. These devices are usually placed adjacent, over or along the highways, roads, traffic facilities and other public areas that require traffic control .
Other traffic calming measures, such as street design strategies, may be more effective in reducing speed and improving safety over time. Considering the long-term benefits and potential cost savings.
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 ...
Adaptive traffic control. Adaptive traffic control system (ATCS) is a traffic management strategy in which traffic signal timing changes, or adapts, based on actual traffic demand. This is accomplished using an adaptive traffic control system consisting of both hardware and software.
Several techniques exist to reduce the delay of traffic. Generally the algorithms attempt to reduce delays (user time), stops, exhaust gas emissions, or some other measure of effectiveness. Many optimization software are geared towards pre-timed coordinated systems. Normally optimization of signals along a road is a challenging and expensive ...
Traffic lights that do not service traffic due to non-detection may not meet the federal legal definition adopted by most states for a traffic control signal, which is any device "by which traffic is alternately directed to stop and permitted to proceed". [1] [2] [3] Meeting this definition is required for any citation to be upheld; traffic ...
