A Review of Tiramisu - Extending Transportation Information Systems with

Title: A Review of Tiramisu - Extending Transportation Information Systems with Crowdsourcing
Speaker: Anthony Tomasic, Institute for Software Research, CMU
Date: Wednesday, Feb 8th
Time: 12p-1p
Room: GHC 6501

Abstract:

Tiramisu ("pick me up" in Italian) is a prototype implementation of a transportation information system that learns via crowdsourcing information from users. Through a smart phone interface, transit riders search for transit information. Once on a bus, riders contribute new information to Tiramisu through the same interface. The system also leverages the instrumentation of the smart phone to create an automatic vehicle location (AVL) service. Tiramisu is currently deployed in the Pittsburgh region. The system serves as a test bed for a variety of research areas: crowdsourcing system design, universal (accessibility) design, applied machine learning, and service design. In this talk, we will discuss our initial design rational, review research results to date, cry mea culpa over design mistakes and present some new preliminary results. If time permits, we will discuss some future directions.
Joint work with Charlie Garrod (CSD/Swarthmore), Yun Huang (RI), Aaron Steinfeld (RI), John Zimmerman (HCII & Design) and many others.
