Frequently Asked Questions
How close are the times?
Times are estimates and may change due to unexpected traffic or conditions.
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 and trip results stay in this browser. When signed in, successful plans—including addresses—are encrypted and saved to your account history. We do not sell your data.
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.
