The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.
About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times.They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called “visualizations”.These visual representations help emergency workers better understand what is happening.
The center shares its findings with firefighters, police, transportation departments and the military.They also share information with universities and transportation companies.The technology company Google uses the data for its traffic-related websites.Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.
Mr.Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.
