Background
No comprehensive source for Chicago traffic data. Most available data is from disparate sources.
OEMC receives hundreds of FOIA (Freedom of
Information Act) requests each year for traffic data.
Many states and local governments provide a web
based traffic information map. http://www.i-move.ca/Motorists (Vancouver)
http://www.leedstravel.info/cdmf-webserver/jsp/leeds.jsp (Leeds, UK)

Considerations
Works faster on FireFox and Chrome browsers.
Hundreds of markers on the map will cause the
map/website to operate slow.
Website performance is depended on the
computer’s memory.
Google licensing does not permit linking the
website with any internal applications.
