About fifteen years ago, the Federal Communications Commission created a new classification of two-way radio to be known as the Citizens Radio Service. It utilized the AM mode at 11 m band. Since that time equipment size has been greatly reduced and numbers of units in operation have increased radically. From individual reporting of accidents, there has evolved a nationwide network of control centers. Most centers are manned on a voluntary basis; however government and businesses are now setting up control centers. Ohio is initiating a test program in 1970. This program will have state and regional personnel and will work directly with the State Highway Patrol. The prospects for future expansion is good due to technological developments and increased interest by government agencies.
