Give your intersections
an invisible crossing guard.
Roundabout sees every car, bike, and pedestrian, recognizes unsafe situations, and makes the signal change that will keep everyone safest.
Protect pedestrians
with a dynamic green extension to hold off oncoming cars
Protect cyclists
with dynamic all-red phase extensions
Keep drivers out of Type 2 Dilemma Zones
by tracking their position and approach velocity
Each line represents a vehicle trip — some trips slow down at the stop line and some keep going. The horizontal dashed line represents when the light changes. Vehicle lines that cross this line indicate trips that will encounter a red light.
Traditional Detection System
Real data, pre-deployment. Stop line detector with 3s extension time. Many vehicle trips cluster near the decision zone, leading to red light running
Actual deployment data. Far fewer trips fall close to the dilemma zone.
By tracking when people make the decision to run a red light for every approach, our system identifies those few seconds when people are more likely to run red lights and keeps vehicles out of that zone by changing the light either earlier or later. As a result, very few vehicle trips fall close to the dilemma zone.
