Intersection Management Radar.
Easy to use. Robust. Truly universal.

smartmicro Stop Bar+ traffic sensors, field-proven since 2009 on thousands of intersections, outperform other technologies in stop bar detection accuracy and reliability. Where competitors need two sensors for the two functions, smartmicro can offer Stop+Advance - combined stop bar and advance detection with one single Radar.

Using 4D multi-object, multi-lane technology, sensors can manage straight or curved roads. smartmicro`s 4D/HD and 4D/UHD (ultra high definition) products allow high resolution detection for best performance even in congested traffic conditions. NEMA TS1/TS2 SDLC compliant cabinet cards, relays and communication plus many other interface options and accessories are offered.

Stop Bar+ (Multi-Lane Stop Bar Detection)

- Replaces loops, outperforms video detectors.
- Detects moving and stopped traffic.
- Works under all conditions.

smartmicro stop bar detectors are robust, reliable and achieve highest detection rates and a very low number of false calls and/or stuck calls. Bicycles can be detected.

Up to eight lanes, no matter if straight or curved, are covered. One radar replaces up to 64 loops. 

Sensors are usually mounted on existing poles at the corner of the intersection or on a mast arm.

The applied radar technology is maintenance free.

Stop+Advance (Combined Stop Bar And Advance Detection with one Single Radar)

- One single radar for both stop bar and advance detection.
- Lane specific advance detection.
- ETA, counting, traffic statistic and other applications.

The three statements above summarize the key differences to other detection products and explain why this smartmicro traffic solution by far outperforms competitors. It saves cost both in terms of hardware and installation by integrating many functions in one.

The smartmicro sensor allows adaptive control strategies for intersections, because lane specific advance detection is possible. 

Therefor it represents the most universal detection technology on the market. Covering a wide field of view the sensor provides presence information at the stop bar and at advance zones. stop bar, approach, advance and system loops can effectively be replaced.

In addition to simple presence detection the integrated Event Trigger Module can be used to realize dilemma zone protection, signal priority, signal phase extension and other concepts for modern actuated intersections.
