Road Weather Information Systems

Coral Sales Company proudly represents both permanent and mobile Road Weather Information Systems. Highway information systems manufactured by Lufft and Vaisal

M.H. Corbin SolarMax Portable Highway Advisory Radio (HAR)

The SolarMax Portable Highway Advisory Radio (HAR) System keeps traffic flowing by broadcasting up-to-the-minute radio advisories to motorists. The flexibility of the SolarMax HAR allows for quick 10 minute or less set-ups. Solar charged power offers dependable service around the clock and during extended periods of inclement weather. This Portable HAR System utilizes low power AM radio to inform motorists of conditions ahead, giving them enough time to take action or alternate routes. The system can be used as a work zone HAR to assist in managing a construction site, a temporary incident, inclement weather evacuation, or a frequently congested traffic area. Messages can be changed quickly and remotely should conditions vary, and when the job is finished, the SolarMax System can be ready for duty on the next upcoming project.

Features

  • Simple and quick to assemble, deploy and disassemble
  • Broadcasts messages to motorists in a 3 to 5 mile radius
  • Robust design, including built-in lightning suppression
  • Meets all FCC rules and regulations
  • Weather-resistant and theft deterrent enclosures
  • Portable ground system
  • On-board digital recorder preserves audio messages with no external power source

Modular Components

Highway Advisory Radio (HAR) systems from MH Corbin utilize AM, FM and CB 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 MH Corbin HAR is one of the most practical ways to get the message out to everyone.

 

Advanced Applications with Platinum Software

Message recording, editing, review, scheduling and synchronizing are quick and easy through the intuitive graphical user interface that features map displays for each HAR system in your network. Manage and store a library of messages for quick release to the public, including the capability to execute commands for your entire HAR network in just a few simple steps. 

Platinum can manage other transportation communication devices such as flashing beacons and variable messages signs (VMS). The software also has the ability to monitor set parameters and alert an administrator or user through email. The software system consists of a central server that manages and stores all information about the devices, and a client software that allows a user to manipulate and control the central server.

 

Lufft MARWIS-UMB

The Lufft Mobile Advanced Road Weather Information Sensor (MARWIS) is the most affordable weather sensor on the market. The MARWIS sensor is easily mounted to almost any vehicle and connects wirelessly to your smart phone or tablet via Bluetooth. MARWIS collects weather data such as relative humidity above the road surface, dew point temperature, ice percentage, road friction and more! The measured data continually displays real time road information in the vehicle and can also be sent to your local Traffic Management Center (TMC). 

Features

  • Wireless Bluetooth connection.
  • Real time data to your smart device or TMC.
  • Measure road surface condition, roadway grip friction and more.
  • The most cost effective mobile weather sensor on the market.
  • Mounts easily to almost any vehicle. 

 

Easy Data Communication

MARWIS offers various solutions for easy data handling. The analysis of data measured occurs either in the ViewMondo Software, or by means of the alternative solutions. The open interface protocol ensures effortless integration into existing measuring networks.

Via Bluetooth, MARWIS sends collected data directly to an iOS- or Android-based tablet or smartphone in vehicle car for real time evaluation. Using a data cloud, the measurement values can directly be delivered to the ViewMondo visualization software in the operations center. Consequently, authorized persons, such as operations managers, are able to digitally accompany and protocol patrol tours. Thus, routes can always be changed or cleared efficiently.

                                

Evaluate Data in Seconds

MARWIS collects weather data as temperature, relative humidity, dew point and road conditions (dry, moist, wet, ice/snow, chemical wet). Moreover, it determines ice percentages and calculates the weather-related surface friction. It transfers the data measured continuously and in real time via Bluetooth to a tablet, smartphone or an alternative output device in the driver cab. By means of a data cloud, the MARWIS App is able to forward its measurement values to an operations center, where operations managers can track patrol tours – with the ViewMondo management software, for instance.

 

Get The MARWIS APP

The MARWIS App is available for free and supports both iOS and Android platforms. Connect your MARWIS via Bluetooth™ to the Lufft MARWIS App you get the following functions:

  • Visualization of the readings
  • Configuration of the sensor

Surface Patrol

The Surface Patrol is a mobile weather sensor used to detect possible freezing temperatures on pavement by measuring the pavement and air temperatures. The data retrieved from Surface Patrol is accurate and real time, making it a reliable method for collecting pavement information and helping to determine when anti-icing road treatment is necessary. Installation options are available for integration with chemical anti-icing spreader controllers.

Features

  • Measures both air and pavement temperatures.
  • Easy-to-read, dash-mounted digital display.
  • Patented cone design to protect sensor lens.
  • Separate air sensor for improved accuracy.
  • Optional to connection to spreader controllers.
