A traffic camera is a video camera which observes vehicular traffic on a road. Typically, these are put along major roads such as highways, freeways, motorways, autoroutes and expressways, as well as arterial roads, and are connected with optical fibers buried alongside or even under the road. A monitoring center receives the live video in real time, and serves as a dispatcher if there is an traffic collision or some other disruptive incident or road safety issue. Internet users can often view individual frames posted to a website every few minutes, and can then determine whether an alternate route should be taken.
