Problem: Old Traffic Infrastructure and booming growth
Seattle has been the fastest-growing large city in the country twice in the past decade. The growth spurts the city has gone through brings tremendous excitement to the economic growth. But this comes at a cost to the city’s transportation substructure and keeping up with the ever-demanding increase of congestion.
The Seattle Central Business District (CBD) is the heart of mobility throughout the city. It is also the oldest infrastructure of employed controllers, that are 20+ years old. Although these controllers were industry leaders in their day, they have limited functionality based on today’s needs and standards.
Until a year ago, CBD data was sent to and from the controllers, all 300+ of them, at the same time. It consisted of one pattern, at specific times of the day, with no relevance to the traffic or demand. Information about these large influxes of traffic coming to or from the south; such as Centurylink Stadium (home of the Seattle Seahawks), Safeco Field (home of the Seattle Mariners) or from the north; such as Key Arena or the surrounding area around the Space Needle, was not being distributed throughout the network of intersections. City engineers, planners, and designers needed a way to share information, predict what is to come, and deal with the growth, while utilizing an infrastructure that is limited.
