A traffic camera is a vieo camera which observes 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 dispatch if there is an automobile accident or some other disruptive incident or 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.
