A Requirements Analysis Document for Transit Vehicle Wheelchair Lift Devices

摘要

The purpose of the document is to provide guidelines for the design and evaluation of wheelchair lift devices for public transit vehicles (buses and light rail vehicles). Included is an analysis of wheelchair and maneuvering dimensions and their impact on both the lift system and transit vehicle design. Much of the content deals with general safety considerations and vehicle interior design which are the same for ramp or lift devices. A total of sixty three (63) requirements and recommendations are presented covering the design and operation of the lift, the vehicle lift interface, the vehicle interior, and the reliability and maintainability of the system. In addition, the report discusses evaluation parameters needed to assess the cost of public transit lift devices.
