Transit Vehicles Reference Designs

This web-based infographic resource illustrates two “reference designs” of small buses built on truck chassis manufactured by major manufacturers. A reference design is a concept showing features and functions without engineering and design details. A reference design is meant to encourage innovation without being prescriptive.

These buses are often used in shuttle operations, end of the line service, flex-bus service, and on demand transportation services. The infographic shows many “universal design” features that can be included in a bus to provide more accessibility and usability for all passengers than currently included as a minimum response to ADA and other regulatory requirements. The features illustrated could be incorporated on buses individually or in combination.

Two different designs are presented because the location of the entry door leads to different locations for wheelchair securement. Both designs are based on the low floor concept, which allows wheelchair users to board with a ramp rather than a lift. The main innovations illustrated include space for two wheelchair users, a ramp with a lower slope than the regulations allow, enhanced rider information, an automated wheelchair securement system, enhanced stanchions and railings, easier fare payment, improved storage, and improved lighting.

The reference designs will lead to greater safety, ease of use, comfort, improved understanding of the transit system, and usability of specific routes, for all riders.
