Traffic congestion on urban freeways is a big problem, especially in busy areas where adding more lanes isn't always possible. One solution being looked at is automation, which can help increase freeway capacity without needing to build new lanes. In a study in Sacramento, California, researchers used a transportation model to see how automation could affect things like how much people drive, how long they're stuck in traffic, and how many people use public transportation. They looked at different scenarios, like what things would be like in 2010 with and without freeway automation. The results showed that automation could have a positive impact on reducing congestion and improving travel behavior in the region.
