* '''Los Angeles''' - Metro initially struggled to get legislative approval for HOT lanes on I-10/110, but succeeded with the support of State Senator Mark Ridley-Thomas. The project got off the ground when Metro promised to study the effect on low-income commuters and closely monitor the program.
* '''Orange County''' - Four variably priced express lanes were opened on State Route 91 in 1995. The tolls are changed every three months to account for traffic volumes. Average peak-hour speeds on the express lanes is 60-65 miles per hour, as opposed to 15-20 miles per hour in the general lanes. Not only has the project been financially successful, but it has allowed drivers to travel much more quickly.
