Transit Usability Study Results:

The RERC on Accessible Public Transportation will research and develop methods to empower consumers, manufacturers, and service providers in the design and evaluation of accessible transportation equipment, information services, and physical environments.

Project Description:

Bus Figure

The Rehabilitation Engineering Research Center on Accessible Public Transportation conducted a global online survey of usability problems on public transit buses. The study investigated getting on and off public buses, circulating inside them, understanding their communication and information systems, as well as issues concerning rider safety. The information collected from this study will help identify public bus features that merit further detailed experimental research in controlled settings. The survey targeted a wide range of stakeholders including: manufacturers, designers, engineers, researchers, and riders (of all abilities).

Not only were we interested in learning about the problems users encounter on public buses, but also in gathering (1) “excellent examples” of accessible public transportation in cities participants have visited and (2) what they envision for the bus of the future.

Research Questions:

  1. Which features related to using public buses merit future detailed experimental research?
  2. What/where do users identify as accessible public transportation best practices?
  3. Which features need to be addressed when designing the next generation accessible transit bus

Data Collection:

Data was collected online using the survey tool survey monkey. The survey was available from September 2010-April 2011 through both the udeworld.com and rercapt.org websites. A total of 372 individuals responded.
