Carpool lanes on SR 55 lead to shorter commutes and increased ridesharing.
The study looked at how travel patterns changed on State Route 55 in Orange County after carpool lanes were introduced. They compared data from before and after the carpool lanes opened to see if trips in the carpool lanes were longer, how much time was saved, and if more people were carpooling. They found that carpool lanes did save time and encouraged more people to share rides instead of driving alone.
