Bus 12, where are you?

A market may be emerging for real-time bus arrival information systems, according to a report from the Federal Transit Administration. These systems provide bus and subway patrons with expected arrival times, drawing updates from automatic vehicle location systems that have been put in place to optimize scheduling. In 2000, 88 U.S. transit agencies operated vehicle location systems, and 142 others were planning them. An arrival information system can report expected arrivals by electronic signs at the stops, through the Internet or through cellular telephones.
