TMB-134 Radar for Multi-Lane Intersections

The TMB-134  is an “all-in-one” multi-lane microwave sensor for traffic signal regulation.

How Does It Work? 

The user can define up to 9 virtual loops, all activated by vehicles or bicycles.  The stop-line detection areas can be configured, per lane, as presence areas: the “loops” are activated until the object leaves the zone.

Why A Radar?

Safer for traffic engineers, who can stay at the roadside during installation.
Less expensive: no road works and no traffic interruption needed for the installation.

Works despite weather conditions like frost, snow, fog, etc.

No lens to clean for maintenance-free operation.



  • Virtual distant loops, activated on movement detection

  • 1 single radar to replace up to 9 inductive loops
  • Right-turn/left-turn detection
  • Easy to use and install
  • Detachable cable at the rear of enclosure
  • Delivered ready to install, including cable, mounting bracket, screws and bolts

The TMB-134 is a new high-precision radar capable of detecting movement and presence on multiple lanes and emulating up to nine inductive loops per radar. It has the capability to detect approaching vehicles and bicycles as well as their presence at the stop-line. The TMB-134 is an intersection radar tailored to crossings with 2 or 3 lanes in one direction and perfectly fits intersections with dedicated phases for right-turn and left-turn lanes. It integrates approach and stop-line presence detection for enhanced traffic light management. If a vehicle at the stop-line does not leave for any reason, the TMB-134 maintains the signal to allow the controller to keep the green light on for longer. The radar is provided with software for the configuration of the loops and can, if necessary, communicate directly with the controller using the RS-485 serial communication line instead of dry contact relays.

Recommended configuration: Min. 8 m (26 ft) from stop-line (at the opposite side of the intersection)
Number of detection zones: Up to 9 detection zones
Detection range: Up to 70 m (230 ft) from the installation point
Operating temperature: From -40 °C to +60 °C (-40 °F to +140 °F)
