In 2010, the fast-growing city of Phoenix, Arizona's Street Transportation Department embarked on a project to reduce both travel times for commuters and operational expenses. Read in the case study linked below how a wireless communications solution from ABB (a Council Associate Partner) subsidiary Tropos helped Phoenix meet its objective of an Intelligent Transportation System that could handle multiple applications.
Improving Traffic Flow with ITS
As of mid-2013, the Tropos network has grown to include 902 radios (approximately 100 of these serve as gateway nodes with most of these connected to city fiber) covering more than 500 square miles. There are also over 100 traffic cameras connected to the transportation department network of which half are connected wireless over the Tropos network (the remainder connect directly to fiber at traffic signals).
