Washington State DOT traffic analysts looked at how many cars were on the road past Labor Day weekends. Based on this historical data, the graphs shows how many cars (vertical axis) we project to be on the road each hour (horizontal axis) for Labor Day Weekend 2015. As the graphs turn from green to yellow, drivers can expect some congestion. During the red hours, traffic analysts predict travel will reach roadway capacity. Once a roadway reaches capacity, any small incident can cause significant backups.
The black line running from left to right show typical summer traffic. This gives drivers more information on how the Labor Day 2015 holiday weekend travel may relate to a typical summer weekend.
