Abstract: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. This effort is intended to leverage our existing system, Tiramisu (“pick me up” in Italian), a social-mobile computing system intended to connect riders and transit service providers using universal design. Under other funds, the team is currently advancing Tiramisu by implementing a rider-to-rider and rider-to-agency messaging system to help improve rider and agency awareness of current transit system state. The deployed message system will also 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. Under this UTC project, the team seeks to research and develop methods for gathering support safety related messaging and other information from related, distributed sources for dissemination through the Tiramisu message channel. The intent is also to provide a method for such messages to also be shared with other TSET UTC systems. While it is straightforward for a programmer to write custom code to extract relevant information from websites, this approach is expensive, brittle, and does not scale beyond a small number of sources. Therefore, the team has focused on methods to allow non-programmers (e.g., administrative assistants, planners, etc) to train the information gathering system on websites of interest. This will allow rapid information gathering from a wide range of sources, low-cost repair when websites change, and scalability.
