FTA Bus Testing Program March 28, 2013

The 2013 FTA Bus Testing Program, led by Gregory Rymarz and supported by Penn State University, focuses on compliance with updated emissions standards and evaluates bus performance under real transit conditions. As of April 2013, no new testing is needed for Cummins 2013 engines. The Passenger Weight Rulemaking has been withdrawn, yet mid-sized buses must still follow requirements from the October 2009 rule. Bus manufacturers can designate standee capacities on models designed for them. Key insights into the testing process and the implications for bus design are featured.

  2. Introductions • FTA Bus Test Program Manager: Gregory Rymarz Office Research, Demonstration, and Innovation • Bus Test Program Principal Investigator: Dave Klinikowski Penn State University • Bus Test Program Technical Advisor Stephen Brady Booz, Allen, & Hamilton

  3. 2013 EPA Emissions • No testing required solely for 2013 emissions requirements • Dear Colleague Letter for 2013 Cummins engines • Cummins EPA 2013 engines would not be available until April 2013 • FTA funds would available to purchase pre-2013 engines before December 31, 2013 • Had to be used for signed bus orders prior to October 31, 2012 and used in buses built before October 31, 2013

  4. Passenger Weight Rulemaking • Passenger Weight Rulemaking has been withdrawn • Bus Testing will continue operating under the October 2009 (over GVWR) rule • Test Buses are “loaded” until no standee space remains • At full test load Mid-sized Buses are typically overloaded (GAWR and/or GVWR) • At full test load, Heavy-duty buses are not typically overloaded • Question – In actual transit service are mid-sized buses operated with standees aboard?

  5. Passenger Weight for Testing - Options • Allow bus manufacturers to specify the quantity of standee passengers on a bus model provided that: • If the bus is designed for standees, a standee line is present and the total quantity of standees is identified • If the bus is not designed for standees, the bus is placarded accordingly on the bulkhead and no standee line is present • Existing Standee loading procedures would be applied to buses that are standee capable (150 lb per 1.5 sq. ft.) • For buses not intended for standee passengers only the weight of seated and wheelchair passengers would be loaded (150/600 lb respectively) • The ability to transport standee passengers will be highlighted in the test report • Comments?
