• Abstract:
  The primary source of information for rider safety with respect to dynamic events such as ; cancelled buses, detours, traffic conditions and other factors is the transit system website. ; Although technological enhancements, such as real-time tracking, rider alert RSS feeds, ; and Twitter feeds, are available for transit users, such information sources do not always ; report updates reliably. For example, some real- time tracking systems stop transmitting ; updates about a bus if the bus takes a detour from its scheduled route. Rider alerts might ; temporarily suspend updates due to holidays or employee PTO. Notifications through ; social media frequently offer information of relevance, but are often difficult to understand, ; or for one to comprehend the impact of the message on their trip. Paradoxically, users are ; still faced with a lot of effort at navigating the appropriate information sources, finding and ; understanding messages and updates of relevance to their trip. ; Our project goal is to access transit service live update data feeds, identify the routes and ; stops on which their updates will have an impact, and provide an integrated display of that ; information in the user’s Tiramisu smart phone app. The extracted information can be used ; in multiple ways to improve the interactive experience of the user and keep them better ; informed. For example, if bus stops will be discontinued between certain hours of a day ; for, say, water main repair, and other stops will be established during that period, a search ; of nearby stops will reflect such temporary changes. This, combined with vehicle fullness ; data from the Tiramisu system, will allow riders to identify alternate transit trip options that ; are not too full to board.
