Vaisala HIS Highway Advisory Radio HAR100 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 Vaisala HAR is the only reliable way to get the message out to everyone.

With a Highway Advisory Radio 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. Vaisala HIS Highway Advisory Radio HAR100 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, Vaisala HIS Highway Advisory Radio HAR100 can provide messages even when the power is out. Vaisala HIS Highway Advisory Radio HAR100 can be installed as a single unit or as a network of GPS synchronized systems that broadcast a single message simultaneously throughout an area.
