The radios contain
GPS receivers and are linked to a wireless metropolitan area network made up of cell transmitter stations that Gateway operates, according to Jon Rowley, the company's president and co-owner. The radio on each bus transmits its location, the GPS data and the
tag manifest over the 218 MHz band, to the cell transmitter stations around Tucson that make up the network. This data is then forwarded to BusPass software running at a central location. The software keeps a record of all tag transactions and GPS positions and notifies parents of arriving or truant students. It can be used in combination with interrogators installed on the school grounds, as an automated attendance-taking system for teachers. The information gathered in the software can also be used to locate buses in case of an emergency.
Initially, says Bill Ball, TUSD's transportation director, the district was looking for a means of just tracking the buses, so as to know where they were at all times and whether drivers were speeding. Officials were intrigued, however, by the ability to know, as well, which students were on each bus, especially if this could help them locate children quickly.
Still, Ball stresses, TUSD had not yet made any decisions about deploying
RFID or any other tracking technology. "We want to be really careful and make sure we get input from parents and students" before deploying anything permanently, he says.
Whether tracking students' whereabouts makes them safer or just vulnerable to privacy is being fiercely debated among many schools, parents and privacy advocates. An elementary school in Sutter, Calif., started testing a passive RFID tracking system for automated attendance-taking early this year, for example, but the program was shut down after parental opposition and involvement from the
American Civil Libterties Union (ACLU) and other privacy-rights groups drew national media attention to the small town.
Enterprise Charter School, in Buffalo, N.Y., deployed an automated attendance-taking system in 2003 in which students present an RFID ID card to a kiosk with an integrated
reader. The high costs of replacement IDs, however, have rendered the system too expensive to maintain, according to Mark Walter, chief technical officer at the school.
"Kids are losing the cards," says Walter, or the students are ruining them. "They're being put through washing machines, kids are chewing on them." Consequently, the school is phasing out RFID and moving to a different attendance-taking system in which each student must find their photo on a computer screen and click on it as they enter a classroom.
READERS' COMMENTS
Loopholes and more designs for the proposed system
The schools implementation has few loop holes and is not tightly integrated. Though the school has setup the RFID tags for monitoring the buses they have extended it to the students. while extending it. the following need to be taken care mandatorily. a) did the student leave the school - b) if yes, did she board the bus c) did she get down in the right bus stop if these are done, instead of clicking on the photographs the student can just walk in to the classrooms where there would be a reader such that his /her attendance can be monitored without the need for an alternative attendance system. once the integrated attendance system is in place, the same attendance system can be integrated with the proposed bus system and this would give the parents more information to know where the kid is ( if school permits, they can extend it to which teacher is teaching the class where the student is right now can be given to the parents)
