<strong>Standard</strong> <strong>Bus</strong> <strong>Procurement</strong> <strong>Guidelines</strong><br />
5.4.5.4 ACCESSIBILITY PROVISIONS<br />
5.4.5.4.1 General<br />
The design and construction of the bus shall be in accordance with all requirements defined in 49 CFR,<br />
Part 38, Subpart B: ADA Accessibility Specifications for Transportation Vehicles - <strong>Bus</strong>es, Vans and<br />
Systems. Space and body structural provisions shall be provided at the front or rear door of the bus to<br />
ac<strong>com</strong>modate the wheelchair loading elevator. Specific requirements, including the number of<br />
wheelchairs to be ac<strong>com</strong>modated, the tiedown and securement devices, and fold-down seats, are<br />
provided in attachments to Part 5: Technical Specifications. Prior to submission of bid, the Contractor<br />
shall provide a plan, including layout drawings for entry, maneuvering, parking, and exiting of<br />
wheelchair passengers, to show <strong>com</strong>pliance with ADA regulations.<br />
5.4.5.4.2 Loading System<br />
A lift system shall provide ingress and egress quickly, safely, <strong>com</strong>fortably, and in a forward direction for<br />
a passenger in a wheelchair from the street level or curb. When the system is not in use, the steps and<br />
passageway shall appear normal, and no portion of the stepwell shall move when the doors open. The<br />
controls shall be simple to operate with no <strong>com</strong>plex phasing operations required, and the loading<br />
operation shall be under the surveillance and <strong>com</strong>plete control of the operator. If the lift device and<br />
controls are at the rear doors, a switch shall be provided in the operator's area to disarm the lift system.<br />
The bus shall be prevented from moving during the loading or unloading cycle by a throttle and brake<br />
interlock system. The wheelchair loading system shall not present a hazard, nor inconvenience any<br />
passenger. The device shall be inhibited from retracting or folding when a passenger is on the platform.<br />
A passenger on the lift platform shall be able to easily obtain support during the entire loading or<br />
unloading operation by grasping the passenger assist located on the doors or other assists provided for<br />
this purpose. The loading platform shall extend no less than 18 inches outward of the bus, with the<br />
transition from the sidewalk to the loading device not exceeding 1/2 inch, and it shall be ramped to the<br />
extent practicable. The platform shall be designed to protect the device from damage and persons on the<br />
sidewalk from injury during the extension and lowering phases of operation. The loading platform shall<br />
be covered with a replaceable or renewable, nonskid material and shall be fitted with devices to prevent<br />
the wheelchair from rolling off the ends or sides during loading or unloading. When the elevator<br />
platform is rising, no hazard shall be presented to passengers between the platform and the bottom edge<br />
of fixed step risers and other parts of the lift mechanism. When fully raised, the transition from the<br />
platform to the floor shall be smooth. Deployment or storage of the lift shall require no more than 5<br />
seconds. The time required to perform other phases of the loading or unloading operation shall not<br />
exceed 15 seconds. The device shall function without failure or adjustment for 500 cycles or 5,000<br />
miles in all weather conditions on the design operating profile when activated once during the idle phase.<br />
A manual override system shall permit unloading a wheelchair and storing the device in the event of a<br />
primary power failure. Hydraulic systems incorporated in the lift mechanism shall <strong>com</strong>ply with the<br />
requirements defined in Section 5.2.2.2.3 of Part 5: Technical Specifications.<br />
Lights in <strong>com</strong>pliance with ADA requirements shall be provided above the doorway equipped with the<br />
wheelchair elevator to floodlight the loading area. The lamps shall illuminate when the elevator is in<br />
operation and shall illuminate the street surface to a level of no less than 1 foot-candle for a distance of 3<br />
feet outward from the lowest steptread edge.<br />
