Frequently Asked Questions

What is VCalm®?

VCalm® is a range of vehicle calming devices developed by Fortel Traffic, Inc.

Are VCalm® products safe?

Yes, VCalm® products are designed to enhance road safety and have been proven effective in various traffic applications.

How do VCalm® Speed Feedback Signs work?

VCalm® Speed Feedback Signs utilize radar technology to capture vehicle speeds, providing real-time alerts to drivers. Additionally, they can store data for traffic analysis, enhancing overall traffic management.

Are VCalm® Speed Feedback Signs effective?

Yes, VCalm® Speed Feedback Signs have been proven to reduce vehicle speeds. VCalm® Speed Feedback Signs with data collection are self-proving, meaning they use data they collect to prove their own effectiveness.

In general, radar speed feedback signs have been shown to be effective in several ways:

Speed Reduction: Studies have demonstrated that these signs can significantly lower vehicle speeds, especially in areas with speed limits or curves. Drivers are more likely to slow down when they see their speed displayed.
Behavioral Change: The immediate feedback provided by the signs raises driver awareness, leading to long-term changes in driving behavior. Drivers tend to become more cautious in areas where they know speed feedback signs are present.
Accident Reduction: By encouraging drivers to adhere to speed limits, radar speed feedback signs can contribute to a decrease in accidents, particularly in high-risk areas such as school zones, curves, and intersections.
Data Collection: These signs can collect valuable data on traffic patterns and speeds, helping traffic authorities identify problem areas and make informed decisions about road safety improvements.
Cost-Effectiveness: Implementing radar speed feedback signs is often more cost-effective than traditional enforcement methods, like police patrols, while still improving safety.

Are VCalm® Speed Feedback Signs self-proving, and what does that mean?

Yes, VCalm® signs with data collection are self-proving. These signs automatically gather and analyze data, demonstrating a measurable decrease in vehicle speeds when drivers encounter these signs. This evidence reinforces their impact on promoting safer driving behavior, enhances reliability, and reduces the need for regular manual checks.

What is curve physics and how does it relate to VCalm®?

When a vehicle approaches a curve, forces like centripetal force, friction, and inertia come into play. To navigate the curve safely, drivers must maintain control and adjust their speed, as higher speeds increase the risk of skidding or rollover, especially in sharp turns or poor road conditions.

Radar speed feedback signs are crucial in these areas, alerting drivers to their speed and encouraging them to slow down. These signs also collect data on vehicle speeds, helping traffic authorities analyze patterns and inform road design and safety measures. By combining curve physics with radar technology, VCalm® systems can effectively reduce accidents in high-risk areas.

How should I use VCalm® products for best results?

For optimal effectiveness, place VCalm® products in clear, visible locations that allow drivers adequate time to react, particularly in areas with known speed issues.

Are VCalm® signs MUTCD-Compliant?

Yes, VCalm® signs are MUTCD-compliant. The Manual on Uniform Traffic Control Devices (MUTCD) sets national standards for traffic control devices in the United States, ensuring consistency and safety on the roads. VCalm® signs are designed to meet these standards, making them effective and reliable for traffic management and enhancing roadway safety.

Are VCalm® signs WATCH-Compliant?

Yes, VCalm® signs are WATCH-compliant. The WATCH (Warning Alerting and Traffic Control for Highways) guidelines ensure that traffic control devices meet specific standards for visibility, effectiveness, and safety. VCalm® signs are designed to adhere to these standards, providing reliable speed feedback and enhancing road safety.

What is the difference between different VCalm® product categories?

VCalm® Speed Feedback Signs: Equipped with radar to display vehicle speeds; available in various sizes and message capabilities.
VCalm® Intelligent Sensors: Focus on data collection (e.g. radar speed detection, license plate recognition, video capture) rather than displaying messages.
VCalm® Message Signs: Programmable with static or dynamic messages; available in multiple shapes and sizes for different needs.
VCalm® Trailers: Portable signs that can be easily transported; available in various sizes for different display and portability needs.
VCalm® Road and Pedestrian Safety products: Designed for pedestrian zones such as crosswalks, intersections, and school zones. These include products like VCalm®PPB Pole and VCalm®N to help pedestrians cross safely, as well as VCalm®FB and VCalm®RRFB to alert vehicles near pedestrian areas.
VCalm® Contractor Supplies: Essential tools for contractors including traffic cones, poles, and regulatory signs.
