SpeedCheck Variable Speed Limit

Alert drivers to adjust to appropriate speeds as road conditions change

Variable speed limit signs manage traffic flow and increase safety by dynamically adjusting the posted speed limit and displaying it in high-visibility-illuminated digits contained within a familiar MUTCD-compliant regulatory speed limit (or school zone speed limit) sign.

These displays are often used to modify and reduce speed limits on highways and other high-volume corridors due to congestion or poor weather, however, they are just as applicable to school zones, work zones, and anywhere speed limits require temporary modification. With the included SpeedCheck Manager software, schedules can be programmed in advance or adjusted on the fly using a remote Ethernet or local Bluetooth connection.

Features

Available in 15- and 18-inch models (for roadways with speed limits up to and over 45 mph, respectively), these durable systems have all the high-visibility and efficiency features our SpeedCheck radar speed signs are known for:

• Industry-leading high-contrast display technology for visibility in all weather and lighting conditions
• Proprietary safety mask that limits the viewing angle to prevent drivers from watching the display as they pass
• Vandal-resistant design that can absorb up to two inches of impact deflection without damage to internal components
• LED display that can be programmed on a schedule or updated on the fly using the included SpeedCheck Manager mobile app or PC software (see below)
• Solar and AC power options
• FHWA/MUTCD and Buy America compliant

Three reasons to choose a Carmanah VSLS:

1. Unique safety masking on display ensures the display is only visible from the front (up to 3 lanes across), preventing drivers from rubbernecking to read it as they drive past
2. 7-segment design improves legibility from a distance
3. Ultra-clear contrast delivers superior viewability in bright sunlight, with no “88” character ghosting

Software

SpeedCheck Manager

The SpeedCheck Manager software allows you to easily set up, program, update, and perform maintenance on the SpeedCheck radar speed sign. It can be accessed locally with Bluetooth from up to 50 ft away. Two operating modes as described below:

1. Standard operation: All settings for 24/7 operation or as a road speed data collector in stealth mode
2. Scheduled operation: Program and manage calendar schedules for multiple SpeedCheck signs, including simple on/off functions, data collection times and operation of external devices like flashing beacons and cameras

SpeedCheck Scheduler

Ideal for school zone applications and anywhere a set schedule is desirable, the SpeedCheck Scheduler is included with SpeedCheck Manager and allows you to program and manage schedules for multiple signs, from simple on/off functions and data collection times to the operation of external devices like flashing beacons and cameras. This easy-to-use scheduler lets you set up to 16 unique events per day over two years.

SpeedCheck Traffic Analyzer

SpeedCheck radar speed signs have built-in data collection capabilities. Users can connect to their SpeedCheck sign and download traffic data to their laptop via Bluetooth®. Traffic Analyzer software is included with every sign, allowing users to plot the data, see the success of their traffic calming programs and identify areas for improvement.

Product Options and Add-Ons

• Variable Speed Limit Sign Options

Variable Speed Limit Sign Options

• DIGIT/DISPLAY SIZE: We offer the high-visibility variable speed limit sign display comes in two sizes: 15″ or 18″. The smaller model is recommended for roadways with speed limits up to 45 mph while the larger is recommended for roadways with speed limits over 45 mph. This is to ensure optimal sign visibility and digit legibility.
• SIGNAGE: Our variable speed limit signs are compatible with FHWA/MUTCD compliant regulatory speed limit signs. These include R2-1 standard speed limit signs and S4-3P school zone speed limit signs.
• MOUNTING: Variable speed limit signs can be mounted on a variety of standard pole types, as well as on an overhead mast arm (typically used in highway applications).
• CONNECTIVITY : All SpeedCheck variable speed signs are equipped with local Bluetooth and remote Ethernet connectivity.
• CIRCULAR FLASHING BEACONS : While variable speed signs are highly visible and effective on their own, they can be further enhanced with Carmanah’s high-intensity circular flashing beacons. This is an especially popular option for school zones.

We put solar to work^™

Whether your project application is a crosswalk, school zone, or 24-hour sign marking, we can run a comprehensive site assessment to confirm the best solar-powered flashing beacon for your project. We run a field-proven software simulation to create a Solar Power Report™ to show you how we did it. Best of all? It’s free, and we can have it ready in 24 hours.
