Intelligent Transportation Systems

GOALS:  Improve the transportation systems to, within, and from Georgia Tech.

METHODS & TECHNOLOGIES:  Client-server architectures, wireless networks, GPS and other location technologies, statistical analysis and forecasting, database, Android programming.

RESEARCH/DESIGN ISSUES:  GT buses circulate on fixed routes with small headways.  Such systems are subject to bus “bunching” – large headways tend to grow even larger and small headways tend to shrink still more.  As a result, some riders wait a long time for service, and then see one full bus followed by another that is nearly empty.  Bunching is the largest single complaint in most metropolitan bus systems.

To date: The team has built a forecasting, computation, and communication system that coordinates the buses to reduce bunching and so provide better service.  Tablet computers on the buses report GPS data in real time to a central server, which processes it and then communicates instructions to drivers via the tablets.  Current focus: fine-tune the system and extend it to other GT routes and off-campus.

MEETING TIME: Mon, 10:10-11:00

ADVISORS:  Professors John Bartholdi (ISyE) and Russ Clark (CS)

PARTNERS & SPONSORS: David Williamson, GT Department of Parking and Transportation

MAJORS, PREPARATION AND INTERESTS:

  • CS, CmpE, CM, ECE, ISyE, MGMT
  • Java + Android SDK: Tablets will be on each trolley and there are many other things we can do (e.g. use wifi beacons to determine location of bus; count passengers boarding/deboarding at each stop)
  • Web-programming: PHP+Yii, Ruby+Rails, user interface design (HTML, CSS) and data management (mySQL and PHP)
  • Data analysis: Evaluate scheme to forecast time until next bus
  • Human resources: Extend a training program for drivers. Survey drivers to understand their experience of the system.
