B1−4: 'Wizard' CB Radio Transmissions Providing Work Zone Safety Messages to Truckers
The Wizard Work Zone Alert Radio is a portable system, which broadcasts traffic safety and work zone information on citizens band radio channels, primarily aimed at long−haul truckers. The system can record and store up to three different messages and transmit over two different CB channels. Messages are seven to ten seconds, and can be pre−recorded or recorded on site. The user has the option of transmitting a message every 30, 60, or 90 seconds. The Wizard monitors CB transmissions on one or more pre−selected frequencies. When it detects a lull, the Wizard will broadcast a safety message. The Wizard uses a standard CB antenna and a 12−volt power source, and can broadcast over approximately four miles. Under development since 1994 the system was approved for use in Pennsylvania in 1998, and was tested in several States under the Midwest States Smart Work Zone Initiative with favorable results.
