Hiway Max Highway Advisory Radio

Products / Highway Advisory Radio / Hiway Max

The Hiway Max product is a stationary HAR System that utilizes AM or FM radio frequencies to broadcast messages to motorists within a four to six-mile radius. The system is typically used to notify motorists of traffic conditions, local points of interest, or emergency and evacuation information. Messages can be changed remotely by touch-tone telephone or computer.

The Hiway Max application is energy-efficient, easy to operate and can be installed virtually anywhere when used with solar-powered components and cellular phone communications.

The Hiway Max System can be installed as a single unit or as a network of GPS synchronized systems that can be operated from one or more control points. It is simple to record comprehensive messages and allow motorists to receive constant updates throughout your area and beyond.


By the time a driver is in the middle of a traffic jam, information on how to avoid it may be useless. Smart highway management means getting the message to drivers before they encounter delays -- and add to traffic problems.

Whether you're managing a long-term construction site, a public arena, city/county, emergency management or a frequently congested traffic area, Hiway Max by Highway Information Systems can help keep traffic flowing by broadcasting up-to-the-minute AM or FM radio advisories to motorists.

Hiway Max highway advisory radio systems can broadcast messages to motorists typically four to six miles away -- enough time to inform motorists of the situation ahead. (The range of your station may be greater or less, depending on several factors) Should conditions vary, messages can be changed remotely with a quick call from any touch-tone telephone or optionally by computer.


Hiway Max's energy-efficient design uses less power than a 60-watt light bulb. A battery backup system provides dependable service around the clock -- even during extended power outages. And solar and digital cellular phone options allow you to install Hiway Max virtually anywhere, including areas where utilities are not readily available.

A rugged, solid-state design is practically maintenance-free and enables Hiway Max to provide years of service. Because it's manufactured by Highway Information Systems, Hiway Max comes standard with a five-year limited warranty on parts and labor.


Install Hiway Max as a single unit or as a network of multiple systems that can be operated from one or more control points. Easily record comprehensive messages and use Hiway Max in concert with a variety of signs to allow motorists to receive constant updates throughout the affected area. With a GPS Synchronized network, HARs can be setup to cover extensive areas.
