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
Real world data from the report indicated that the total number of accidents increased between 1996 and 1997 from 27 to 30. Personal injures increased from 5 in 1996 to 13 in 1997.
