Seattle is one of the fastest growing cities in America, there's thousands of new people
moving in, many new job opportunities, and we have a limited number of streets.
We have to really use technology where we can to try to improve the safety and efficiency
for all travelers.
Acyclica's devices provide travel time information on Seattle's streets and the Seattle Department
of Transportation has deployed over 300 of the units throughout the city.
Each unit consists of a small sensor that's installed inside of a traffic signal, and
those sensors recognize when a Wi-Fi enabled device such as a smartphone and a vehicle
have moved past a location.
They immediately encrypt that device information, and using a collection of those encrypted
values, they will let it determine how long it's taking vehicles to approach, stop and
leave intersections.
We use that information to understand traffic flow and congestion, to modify traffic signal
timing, and to also provide real-time information to travelers.
This data gives us the opportunity to help move people through the city in the most efficient
way possible when they are armed with additional information to make more informed choices.
