Houston Radar SpeedLane® Pro is a state of the art true dual beam, low power side-fire radar. It is designed to accurately detect lane, speed and class of individual vehicles and compute per lane volume, occupancy, gap, average speed, 85th percentile and headway parameters.

SpeedLane Pro
  • Patented (US Patent: US10317525 & EU Patent: EP3117235) true dual beam “speed trap” technology inherently provides accurate measurements without the need for in situ calibration.
  • World’s lowest power usage highly integrated multi-lane traffic measurement radar. At 1.0 Watts the SpeedLane® Pro requires 10X less power than competing products.
  • FCC and CE listed for full 250MHz operation to suit variety of application requirements.
  • Mounts on the side of the road for non-intrusive traffic data collection and works in all weather and lighting conditions.
  • Simultaneously measures all vehicles in 16 user defined lanes.
  • All traffic measurements are on per-vehicle, per-lane basis, available in real-time and stored in device memory.
  • Lane-by-lane vehicle counts, length based class, average and 85th percentile speeds, occupancy, headway and gap measurements.
  • Companion Windows application provides intuitive GUI to set all configuration parameters, display real time plots of targets and view snapshots & streaming HD video.
  • Built-in long range Class I 2.1+EDR Bluetooth, RS232/RS485 serial ports and Ethernet.
  • 512 Mbytes of on-board storage plus uSD card expansion slot.
  • Built-in 1.3MP HD video camera for sighting makes setup a snap and allows convenient remote monitoring of traffic.
  • Comprehensive Houston Radar protocol, C and C# SDK.
  • Powerful SQL-based query interface for historical data.
  • Optional cloud-based Tetryon server to aggregate data from multiple devices provides a quick and seamless dashboard view.
  • Optional automatic data upload to MS2 Traffic Data Management System.
  • Optional built-in UPS with rechargeable battery keeps unit running for  up to 96hrs on loss of external power.
  • Optional MPPT solar charger for optimal winter and cloudy day charging.
  • Optional internal 96Whr LiFePO4 battery for temporary or solar installations.
  • Optional LTE CAT-1 4G cellular modem for remote access in North America only.
  • Optional LTE CAT-M1 4G World Wide modem for worldwide remote access.
  • Optional built-in PoE (Power over Ethernet).
  • Optional Ethernet
  • Available 2, and 4 channel Loop Replacement Cards (LRC) for US NEMA and UK MIDAS (4ch only) cabinets allows interfacing to legacy loop systems.
