Stalker Traffic Control Sensor

The Stalker Traffic Statistics Sensor is a self-contained system to monitor and internally record traffic patterns on roadways in virtually any location and weather condition.

In addition to its statistical capabilities, the unit can track up to 10 moving vehicles simultaneously and operate as an ordinary speed sensor feeding strongest and fastest target information to external systems through a RS-232, RS-485, USB Communication, or USB flash drive interface.

The Stalker Traffic Statistics Sensor allows data to be collected and easily downloaded to a PC for analysis and presentation using the Stalker Traffic Statistics App.

Designed for use with the Stalker Traffic Analyst

Updated analysis control allows you to take raw data and display it by count vs time, count vs speed, and 85th percentile, just to name a few. Data can be split, graphed, filtered, and then rendered in a color report designed with Agency branding and support information.

Beginning with the setup, the actual sensor can be configured. Then, the intuitive survey management tools walk the user through calendar setup, location details, speed and time resolutions, vehicle classification, speeds, distances, and more.

  • Intuitive Survey and Calendar setup
  • Visual analysis controlled by floating pallets
  • Compare and toggle between multiple reports
  • Combine analysis screens onto common report
  • Group file operations into project folder
  • Powerful, user-defined report generation
  • Built-in sensor configuration and setup
