Work Zone Trailer

by Fortel Traffic, Inc.

Fortel Traffic’s VCalm®TWZ is a powerful traffic calming message board with the added versatility of a trailer that provides a simple way for a single operator to relocate the sign. VCalm®TWZ is a summation of the most important features and technology that meet the evolving needs of the traffic and construction safety industry.


Brightest Display

VCalm® utilizes high-volume high-intensity tightly clustered LEDs to maintain the highest visibility possible. This proven method of authoritative message presentation demands driver’s attention, making it the most effective traffic calming sign on the market.

Unrivaled Versatility

  • Custom Messaging based on unique road conditions, activities, or events
  • Multiple independently-scheduled vehicle speed thresholds can trigger any variation of messages and/or auxiliary devices: strobes, flashers, sirens, beacons, wireless alerts, etc.
  • Instant Critical Messaging allows you to quickly display a high priority message from a remote location (requires IP modem).

Lowest Power Consumption

VCalm® uses proprietary PWMS™ LED technology that consumes 50% less power than common LED devices. This provides exceptional autonomy for solar/battery installations.

Strongest Construction

VCalm® maintains superior construction and durability with high quality components and no moving parts. The design meets the NEMA-3R specifications, and many of the VCalm® signs have withstood severe conditions, including hurricanes, fires, and extreme temperatures. VCalm® has consistently proven to be the longest lasting speed sign in the industry.

Easy and Accurate Reporting

  • Traffic Data Acquisition System (TDAS) collects the fastest and slowest speed for each vehicle. The software uses this data to calculate the percentage of slowing vehicles and prove the device’s effectiveness.
  • Accurate raw data collected by VCalm® can be used to construct limitless report formats and parameters for thorough data analysis.
