FAQ
How close are the times?
They are estimates from available live traffic data. Traffic can change quickly, so use Green Light as a planning guide and leave extra room for important trips.
What do the colors mean?
The shortest option is marked as best. Green is within about 10% of that time, yellow is up to about 50% longer, and red is anything slower.
Where is my route stored?
Without an account, recent routes are stored browser-local in this browser so you can reuse addresses. When signed in, successful plans are saved to our databases. Address information is never saved.
Can I plan another day?
Yes, choose a future date and window. To share public resources and protect against abuse, time windows must be 3 hours or less.
