Using Voices - Not Beeping - to Warn Pedestrians
Tuesday, October 27, 2009 4:56 PM
Cleveland pedestrians on crosswalks will soon hear a voice warning them that a bus is approaching, the first vocal alert system in the nation.
After two fatalities in which pedestrians were struck by a bus while at a crosswalk, the Greater Cleveland Regional Transit Authority decided to change the warning beep to an automated voice that will be broadcast from stereo speakers inside and outside the bus, according to The Plain Dealer.
Research shows that people pay more attention to the sound of a human voice than they do to beeping.
The vocal warning system will be installed in the steering column and activated when the driver turns at 45-degree angles.
About 400 buses will get the new system, costing about $600,000, which is coming from federal stimulus money.
The message can be changed and the volume adjusted, depending on the noise level of the environment.
