Distributed Transit Rider Messaging

Uncertainty, lack of transit system awareness, and feelings of isolation have negative impact on all riders, regardless of abilities, thereby reducing community livability and transit demand. Lower transit demand, in turn, decreases economic competitiveness and environmental sustainability. The goal of this project is to facilitate information sharing as a means of improving the transit experience of all riders, especially for those who cannot drive. The system, Tiramisu ("pick me up" in Italian), is a social-mobile computing system intended to connect riders and transit service providers using universal design. Tiramisu's development has been funded by the Rehabilitation Engineering Research Center on Accessible Public Transit and the Traffic21 program. It has been deployed since the summer of 2011 through a spinout company Tiramisu Transit, LLC and is available to the public at www.tiramisutransit.com. Tiramisu is currently advancing by implementing a rider-to-rider and rider-to-agency messaging system to help improve rider and agency awareness of current transit system state. We will adapt this system to support safety-related messaging and information sharing with other Carnegie Mellon University-Pennsylvania State University Transportation Centers (CMU-Penn UTC) systems. The system will allow riders to report situations observed and for the transit agency to push out critical news to riders who may be impacted by an unfolding situation.
