High Sierra Electronics Expands Suite of Road Weather Information Systems for Driver Safety

StormLink RWIS Lite Icy Road Warning Station

GRASS VALLEY, CA – High Sierra Electronics, Inc., a leading manufacturer of environmental monitoring systems for the protection of lives and property, today announced the release of its new StormLink® RWIS Lite range of road weather solutions. The StormLink RWIS Lite Icy Road Warning System and StormLink RWIS Lite High Water Detection System provide economical options for local cities and municipalities to enhance motorist safety by installing warning systems that notify travelers of dangerous road weather conditions.

The StormLink RWIS Lite Icy Road Warning System alerts drivers about hazardous conditions created by winter weather in real-time. Sensors measuring road temperature, and other atmospheric conditions such as air temperature, and relative humidity determine if icy road conditions exist, and automatically activate flashing beacon warning stations on the road. Agency personnel access a centralized dashboard to view system data and set up real-time alerts via Contrail® software. The flashing beacon signs warn drivers in advance of icy conditions so they can be prepared and take necessary precautions such as adjusting speed or finding alternate routes.

The StormLink RWIS Lite High Water Detection System (HWDS) warns drivers of flooding events on roadways. Real-time sensors track water levels at the low point of the road and send alerts through Contrail to agency personnel and warning stations when water levels breach a custom set threshold. The flashing beacon warning stations will turn on, providing drivers with ample lead time of the flooding event to avoid dangerous situations.

These StormLink RWIS Lite solutions provide cost-efficient and scalable products for road weather sensing and warning. Wireless communications and solar powered systems make StormLink RWIS Lite easy to install, even on existing signs. Each package includes a control station, two warning stations for either side of the roadway, and Contrail data management services. StormLink RWIS Lite products fit into the complete network of StormLink products, enabling a packaged safety solution for smaller cities and municipalities.

 

“Weather can impact roads very quickly,” said Brett Hansen, Road Weather Product Manager, High Sierra Electronics. “Measuring road conditions along with alerting drivers on the road is important to keeping both large and small communities safe from severe weather. We are excited to play a larger part in improving weather safety in areas where it is needed the most.”

The addition of the StormLink RWIS Lite product line expands an already robust and full-featured road weather product line that includes sensor stations and driver warning systems. The StormLink RWIS Pro and StormLink RWIS One systems provide additional safety features for larger geographic areas or more complex road weather situations such as high winds and low visibility. High Sierra Electronics also offers integrated camera subsystems and machine learning object detection allowing for visual confirmation and 24/7 alerting.

Levee Safety: New REMS product makes it possible to remotely monitor sites at risk for erosion failure

GRASS VALLEY, CA — High Sierra Electronics announced REMS™ — a new innovative Remote Erosion Monitoring System for earthen levees and embankment dams that is designed to detect when and where erosion has occurred and automatically alert and send information to the levee and dam owners, operating managers, and local public safety officials.

The new automated levee erosion detection system uses a network of beacon sensors that are embedded at levee system or embankment dam sites that are identified as at risk for erosion. If erosion occurs and washes the bank away, the beacons immediately transmit their status. All beacon and site data is managed in Contrail® cloud-hosted monitoring software where users can keep track of the REMS site status. Changes in beacon status can send custom alert notifications to varying stakeholders via e-mail, SMS, or text.

The REMS is being tested for the first time for a Levee Safety project, funded by a CA DWR Grant, on the Sacramento River 35 miles north of Sacramento, in a multi-agency collaborative effort to help detect erosion early and alert the levee owners. The sites chosen for the project are at vulnerable locations along the river where erosion occurs very quickly.

“We developed REMS to address one of the major safety risk factors associated with levees, and that’s erosion and the potential for levee failure and flooding. With increasing populations in leveed areas, the lives and property of those living behind the levee can be at great risk,” said Tom Ogden, Product Manager. “At High Sierra Electronics, our expertise for the past 29 years is real-time monitoring using sensors and telemetry. We put these to use in public safety and warning systems and we looked at how we could apply similar technology in this application where there are clearly some major risks,” he explained.

Most of the nation’s levees are earthen embankments constructed of sand or soil which can erode easily due to the long-term effects of seepage and saturation, overtopping, and fast-flowing water. While today’s new levee systems are designed and constructed to high engineering performance standards and guidelines established by the U.S. Army Corps of Engineers, many existing levee systems were not built to current standards. Adding to the risk is the aging infrastructure — the average age of levees in the U.S. is 50 years. These levees require regular inspections, maintenance, upgrades, and patrolling for high water. Levee erosion becomes a huge challenge to monitor, often not visible and missed because of what’s going on below the surface. As the levee systems get older, inspections and maintenance become more challenging.

“We believe REMS to be a really cost-effective solution that will make it possible to monitor potential levee erosion sites 24×7 and alert key personnel about problems early so they can take timely action,” added Ogden.

There are estimated to be about 100,000 miles of levees in the U.S. Two-thirds of the U.S population are in counties that have at least one levee. Thirty thousand miles of levees are documented in the National Levee Database, with 97% of these earthen levees. The U.S. Army Corps of Engineers has responsibility for over 14,000 miles of levees under its Levee Safety Program. A further estimated 85,000 miles of levees are privately owned and operated.

In the last five to six years, the Army Corps has conducted inspections of levees under its Levee Safety Program. With about half of them inspected today, the Army Corps reports that 20% are of moderate- to higher-risk, with bank erosion considered one of the top three risk factors.

REMS is aimed at local levee owners, levee safety authorities, levee stakeholders, states, local governments, tribes, and private entities. Learn more about REMS, Remote Erosion Monitoring System for levees.
