"The savings will continue to grow as more trucks, PrePass-equipped weighstations and toll facilities adopt time- and fuel-saving technologies," saidRichard P. Landis, president and CEO of HELP Inc., the public-privatepartnership that offers PrePass and PrePass Plus.

PrePass is a sophisticated technology that enables qualified motorcarriers to comply electronically with state-established weight, safety andcredential requirements at highway speeds. By avoiding weigh station stopsand idling in queues, motor carriers reduce fuel consumption and theassociated pollutants. PrePass will electronically process more than 57million weigh station events this year, saving carriers at least 11.4 milliongallons of fuel. Based on EPA engine idle reduction and household emissionestimates, PrePass will reduce emissions by at least 115 thousand metric tons,the equivalent of emissions from more than 6,000 U.S. households.

PrePass Plus allows commercial operators to use the same transponder topay E-ZPass tolls electronically. With a monthly E-ZPass bill in excess of $14million dollars, PrePass Plus is the nation's largest toll customer. "Thebenefits accumulate even more when the savings from E-ZPass electronic tollcollection (ETC) are included," said Michael Huerta, president of ACSTransportation Solutions Group, the largest E-ZPass system integrator andoperator. "Last year there were 3.4 billion toll transactions by E-ZPassoperators, of which 2.1 billion were ETC."

Based on engineering estimates by MARK IV, the E-ZPass technologyprovider, during 2007 alone E-ZPass reduced fuel consumption by almost 30million gallons. That's the equivalent of nearly 265 thousand metric tons ofrelated emissions or the greenhouse gas emissions of about 14 thousand U.S.households.

By reducing congestion in and around weigh facilities and tolling centers,PrePass and E-ZPass also improve highway safety. PrePass enables enforcementpersonnel to concentrate on those trucks most likely to be noncompliant, whileE-ZPass reduces lane changing and congestion around toll plazas. By reducinggovernment transportation program costs, both technologies enhance resourcesavailable for other needed investments.

Landis and Huerta serve as secretary and vice chairman respectively of theIntelligent Transportation Society of America. Huerta will serve as theorganization's chairman beginning in June 2009.

Launched in California in 1995, PrePass(R) is now operational at 281 sitesin 28 states: Alabama, Arizona, Arkansas, California, Colorado, Delaware,Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Maryland,Mississippi, Missouri, Montana, Nebraska, New Mexico, Ohio, Oklahoma, SouthCarolina, Tennessee, Utah, Virginia, West Virginia, Wisconsin and Wyoming.

Nearly 425,000 trucks have voluntarily enrolled in PrePass to takeadvantage of the time, money and fuel-saving benefits.
