Assessing the Benefits and Costs of ITS Projects: Volume 2 An Application to Electronic Toll Collection

Summary Information

A pilot Electronic Toll Collection (ETC) project was installed and tested by CalTrans on the Carquinez Bridge. This bridge was chosen as the location because capacity at the toll plaza was sufficient to handle peak demands with booths out of service during the ETC demonstration. Historically, traffic on the bridge increased at an average rate of 2 percent each year for several years (129 million vehicle crossings in FY 1992/93 to 140 million in FY 1996/97).

As part of the demonstration project, benefits of installing the ETC system were estimated. Estimates were provided for each fiscal year between 1995/96 and 2005/06.

FINDINGS

Between 2000 and 2001 the time saved for toll transactions was estimated at 2,153 (no units given in report: assumed hours per year based on other data highlighted) for ETC versus tickets, and estimated at 3,533 for ETC versus cash transactions. Also, the time savings for movement through the toll facility was estimated at 19,500. The results indicated a total time savings of 25,193.
