As the transportation system works to become more sustainable, low-carbon fuels for cars and trucks, get a lot of attention.
But there's a big, old problem that's costing the country money, time, and carbon dioxide emissions: traffic.
Chicago is considered one of the most congested cities for trucks, with two bottlenecks in the top 10 most congested bottlenecks in the US, and five in the top 100.

Truck drivers, who move more than 70% of US freight, sit in traffic for over 1 billion hours per year, burning fuel, and emitting carbon dioxide.
