It can be hard to know which route to take. Conditions change too quickly to allow you to check for congestion when you're heading out the door, it's not safe to use your phone to check, and you need to keep your eyes on the road.

Signs like this can help balance traffic, by giving drivers the information they need to avoid the slowdowns.

They're are already in other cities - let's bring some to Honolulu!

Currently looking for the best LEDs and sign-makers.
