A traffic tower is a permanent raised structure providing a clearer view of traffic conditions than can be had from street level and protection for the traffic controller from the hazards of moving vehicles. Some traffic towers are fitted with manually operated lights and or signals. Other traffic towers rely on handsignals to direct traffic. In some cases, traffic towers offer a central control location for lights at more than one intersection. Many traffic towers have been replaced by automated traffic lights . Many remaining traffic towers are significant landmarks and have been retained or moved to other locations as historic structures.

It can also be a narrow strip of island between roads that intersect at an acute angle . If the island uses road markings only, without raised kerbs or other physical obstructions, it is called a painted island . Traffic islands can be used to reduce the speed of cars driving through. When traffic islands are longer, they are instead called central reservation traffic medians , a strip in the middle of a road . serving the divider function over a much longer distance. When making left turns, drivers will often drive over painted islands even though it is technically illegal. Some traffic islands may serve as refuge island s for pedestrians. Traffic islands are often used at partially blind intersections on back streets to prevent cars from cutting a corner with potentially dangerous results, or to prevent some movements totally, for traffic safety or traffic calming reasons.

In telecommunication networks, traffic intensity is a measure of the average occupancy of a server or resource during a specified period of time , normally a busy hour .It is measured in traffic units erlangs and defined as the ratio of the time during which a facility is cumulatively occupied to the time this facility is available for occupancy. In a digital network, the traffic intensity is math frac a L R math where a is the average arrival rate of packets e.g. packets sec L is the average packet length e.g. in bits , and R is the transmission rate e.g. bits sec A traffic intensity greater than one erlang unit erlang means that the rate at which bits arrive exceeds the rate bits can be transmitted and queuing delay will grow without bound if the traffic intensity stays the same . If the traffic intensity is less than one erlang, then the router can handle more average traffic. Telecommunication operators are vitally interested in traffic intensity, as it dictates the amount of equipment they must supply.

Unreferenced date August 2010 A traffic conflict , in transportation engineering , is an event involving two or more moving vehicles approaching each other in a traffic flow situation in such a way that a traffic collision would ensue unless at least one of the vehicles performs an emergency maneuver . Traffic conflicts are defined by their time to collision , post encroachment time , and angle of conflict parameters as well as the vehicles position in time and space. Traffic conflicts have typically been used for transportation safety studies, whereby observing and monitoring individual collisions may be impractical, unfeasible, or unsafe. Traffic conflicts are used as traffic collision surrogates, under the assumption that the same factors affecting collision rates also affect conflict rates, in proportion to the conflict severity, termed conflict hierarchy . The principles of traffic conflicts apply to all modes of transportation involving vehicles operating in a non guided medium, including motorized vehicles , Conflict air traffic control Conflicts airplanes , boats, and bicycles. History Empty section date September 2010 By modes of transportation Motorized vehicles Most traffic conflicts involving motorized vehicles are observed on highways, usually involving lane changing or sudden changes in vehicle speeds rear end collision s , or in intersections, involving a large array of conflict types.
