Traffic signal preemption is a type of system that allows the normal operation of traffic lights to be preempted, often to assist emergency vehicles. The most common use of these systems is to allow emergency vehicles priority by changing traffic signals in the path of the vehicle to green (or in some cases, flashing green) and stopping conflicting traffic. Sometimes, signal preemption is also used at railroad grade crossings to prevent collisions, and by light-rail and bus rapid transit systems to allow public transportation priority access through intersections to ensure they are able to remain on schedule and improving commute times.
The key advantages of signal preemption include their ability to reduce response time for emergency services and to increase safety on the road.
Implementation
Older devices generally operate by use of invisible infrared signals or by visible strobe lights. Each emergency vehicle is equipped with an emitter, a device which emits visible flashes of light or invisible infrared pulses at a specified frequency. A unit, mounted next to the lightbar on a fire engine, connects to the control unit mounted in the cab. Receiver devices placed on or near intersection traffic control devices recognize the signal and preempt the normal cycle of traffic lights. Once the emergency vehicle passes through the intersection and the receiving device no longer senses the remote triggering device, normal operation resumes. Some systems can be implemented with varying frequencies assigned to specific types of uses, which would then allow an intersection's preemption equipment to differentiate between a fire engine and a bus sending a signal simultaneously, and then grant priority access first to the fire engine. There are limitations inherent in the standard signal preemption systems, which rely on line-of-sight communication between the emergency vehicle and the receiver. This leads to some intersections unnecessarily being impacted, and conversely other intersections not receiving the signal in time to clear the intersection for the approaching emergency vehicle. Short-term solutions to these issues have been addressed by the relatively remote placement of receivers (on a pole above the traffic signal, or around a corner that approaches an intersection, for example), and also with physical additions to receiver designs that are less likely to pick up signals unless they are originating from a location certain to be in the path approaching the intersection covered. Research into dynamic route clearance has been made to solve these problems and improve traffic preemption with centrally-based route command and control.
A notifier and receiver mounted between traffic lights.
A common implementation of signal preemption systems is a method of communicating to the emergency vehicle operator as well as civilian drivers that a traffic signal is under control of a preemption device. Known as a notifier, this device is almost always an additional light located near the traffic signals. It may be a single light bulb visible to all, which flashes or stays on, or it may be a more sophisticated system such as that available with some systems, where a spotlight is aimed in each direction. The spotlight will either flash or stay on, which communicates to all drivers from which direction a preempting signal is being received. This informs regular drivers which direction may need to be cleared, and informs emergency vehicle drivers if they have control of the light (especially important when more than one emergency vehicle approaches the same intersection). Typically, a flashing notifier indicates that an emergency vehicle is approaching from ahead or behind, while a solid light indicates the emergency vehicle is approaching laterally.
Often this can be confusing to the motoring public which may not understand its purpose or significance, and requires further education of drivers to react properly. A more prudent approach seems to be notification directly back to the driver of the emergency vehicle in the cab of the vehicle itself, as in the instance of the liminatorTM described below. There are limitations inherent in these standard optical signal preemption systems, which rely on line-of-sight communication between the emergency vehicle and the receiver. Their reliability can be compromised by anything which visually obstructs the emitter ability to communicate data to the receiver. Examples of commonly encountered obstacles include large vehicles such as busses, semi-tractors, curves in the roadway, overhanging foliage, bridges, and even fog. In recent years, GPS systems have been introduced to overcome some of these line-of-sight constraints. However, they are susceptible to a new...(and so on) To get More information , you can visit some products about air core coil, Low Carbon Wire, .
