Some days, a student taking “Seward's Trolley” might have to stand out in the rain waiting for it to show up. Those days may be numbered.
Enter the Trolley Tracking Project, a Web-based program that can show users _ and Campus Safety _ where the vehicle is, and where it's headed next.
The program is the senior project for electrical engineers Jeff Morse, Corey Mathis and Corey Allen. They will demonstrate the tracking project at the 11th annual Steinmetz Symposium on May 11.
Morse describes their work as a “systems-level project” that incorporates the Global Positioning System, computer controls, radio and Web.
A GPS receiver mounted in the trolley feeds data to a microcontroller designed by the team to extract only longitude and latitude data. The data is then converted to analog tones (like a touch-tone key pad) that are transmitted from the trolley to a receiver back on campus. A computer then converts the analog tones to digital data. Finally the position of trolley appears on a map on a Web site.
The project was suggested by David Davenport '93, a scientist at GE Corporate Research and Development. The team's advisor was Prof. Ekram Hassib. They had assistance from Robert Tomeck, campus safety, who supervises the trolley program; David Cossey, computer services, for computer support; and John Sowa, chemistry, who allocated server space for the project.
“This has been a good final project in that it encompasses a lot of different areas of electrical engineering, and allows us to work on problem solving in the real world,” Morse said.
Tomeck, of Campus Safety, sees the tracking project as an important tool in monitoring the activity of the trolley, which he said often gets up to 300 riders on weekend evenings. And of course, says Tomeck, the system will be a boon for the riders: “Instead of calling the driver or `guestimating,' they can look at the Web page and see it.”
The team is to demonstrate their project at the Steinmetz Symposium on Friday, May 11, at 10:50 a.m. (Session II) in Olin 102.
