I-15 Fastrak project in San Diego, CA

FasTrak on I-15 in San Diego, California
Faced with increasing congestion and limited funding, San Diego implemented express lanes in the median of I-15, allowing single occupant vehicles to pay for access to the HOV lanes. The fee is collected with an electronic transponder issued to each user and automatically debited from the driver's account. The charge varies based on the available capacity in the FasTrak lanes, with signs showing the charge before drivers choose to enter the lanes.

In addition to providing choices to commuters, the express lanes have generated approximately $2 million annually that helps pay for transportation improvements in the corridor.

SR 91 in California, focusing on Variable Message Sign

SR 91 in Orange County, California
Opened in 1995 as a four-lane facility in the median of a 10-mile section of one of the most heavily congested highways in the country, the SR 91 express lanes are separated from general-purpose lanes by a buffer and plastic pylons. The fee charged changes by time of day to maintain the free flow of traffic. Opening of the express lanes provided additional capacity in the corridor and resulted in a lessening of congestion on the general-purpose (non-tolled) lanes and lessening of delays for users of the express lanes.

SR 91 customers report saving an average of more than 30 minutes per trip. In addition, since the express lanes were added, average peak-period speeds in the general-purpose (non-tolled) lanes have more than doubled. Customer satisfaction is over 90 percent. Time savings is the primary benefit cited. Users also recognize improved safety as an important benefit.

Queue Jump in Lee County, Florida
A traffic management approach being implemented in Lee County, Florida is a "Queue Jump" - a facility that can be used to bypass areas where congestion is particularly severe and occurs in a predictable pattern. Tolls will vary by time of day and be tied in with the County's existing electronic toll collection system.
