HiWay Max™ Highway Advisory Radio

HiWay Max is a stationary Highway Advisory Radio (HAR) system that utilizes AM or FM radio frequencies to broadcast messages to motorists. Informing drivers before they encounter delays and add to traffic problems is important for maintaining a safe driving environment. Since AM radio is a standard feature in nearly all vehicles, using HiWay Max is the only reliable way to get the message out to everyone.

With HiWay Max you can notify motorists of traffic conditions, local points of interest, or emergency and evacuation information, creating a safer, smoother commute and more informed motorists. HiWay Max can also assist in managing traffic during long-term construction projects, keep traffic flowing near public arenas, during special events, or it can simply be used for frequently congested traffic areas.

Information is available to motorists 24/7, and with battery backup, HiWay Max can provide messages even when the power is out. HiWay Max can be installed as a single unit or as a network of GPS synchronized systems that broadcast a single message simultaneously throughout an area.
