Technical specifications define requirements for heavy-duty transit buses, which, by the selection of specifically
identified alternative configurations, may be used for both suburban express service and general service on urban
arterial streets. Buses shall have a minimum expected life of twelve (12) years or 500,000 miles, whichever comes
first, and are intended for the widest possible spectrum of passengers, including children, adults, the elderly and
people with disabilities.

It is the intent of this specification to describe the design requirements for buses rugged enough to withstand
rigorous intensive daily transit service operations and provide maximum reliability and availability, with a
minimum of maintenance and repair time. The bus shall exhibit maximum passenger appeal in appearance,
comfort and safety, combined with excellence in reliability, operating characteristics, efficiency, and economy of
The bus shall be fully compliant with the applicable requirements of the Americans with Disabilities Act (ADA)
and any revisions published by the Architectural and Transportation Barriers Compliance Board or The Federal
Transit Administration for fixed route operations. Where these specifications exceed the requirements of ADA,
the specification requirement shall apply.
