Traffic congestion map
From Wikipedia, the free encyclopedia
A traffic congestion map is a graphical, realtime or near-realtime representation of traffic flow for some particular area. This might be displayed on a web page for ease of access, to help commuters decide how to avoid congested areas. Frequently these show conditions on highways, but local streets can also be shown.
Data is typically collected via loop sensors embedded in the roadways, then processed by computer at a central facility and distributed as a map view to users.
