Flop of the day: an audible warning system intended to alert pedestrians that a TriMet bus was turning.http://blog.makezine.com/archive/2011/05/follow-up-jeri-ellsworth-vs-talking-buses-trimet-jeri-won.html
The transit agency announced Friday that after three months of testing the system, at a cost of $46,000, the tests had come to the end of the line. Announcements broadcast over external speaker systems on 10 buses didn’t activate when they were supposed to and did activate at inappropriate times, such as when buses were changing lanes.
“It was determined,” a TriMet news release said, “that the technology has not advanced enough to make it an effective tool to help alert pedestrians and people riding bikes that a bus is turning.”
The system was made by ProTran1 of New Jersey, and because the agency bought the book-sized units, they can’t be returned.
Spokeswoman Mary Fetsch said she didn’t know what TriMet would do with the units, but “if there are other transit agencies that would like to try it, we’d be happy to help them out.”
The external announcement "Pedestrians, bus is turning" was in both English and Spanish and was triggered by a full rotation of the steering wheel, which caused the announcement to be too late into the turn. TriMet also tested having the announcement trigger at a half rotation of the steering wheel to test if it provided earlier warning. That activated the announcement too early, as well as during lane changes.
Review of an audible warning device was suggested as part of the comprehensive safety review initiated following last April's fatal bus crash. TriMet began the test on March 1, and after receiving feedback from operators, riders and TriMet safety and training staff, it was determined that the technology has not advanced enough to make it an effective tool to help alert pedestrians and people riding bikes that a bus is turning.
The system was not intended to change TriMet's legal and professional obligation to operate safely, be alert and scan the intersection before turning.
As the technology advances in this area, TriMet would be interested in testing an audible system in the future.
