Traffic Intersection Management, Arterial Management and Smart Cities
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 realise dilemma zone protection, signal priority, signal phase extension and other concepts for modern actuated intersections.

Forward+Traffic Counting and Classification Forward+Incident Detection Forward+Wrong Way Detection
Accurate count and highest quality speed data. Reliably detects stopped vehicles, Automatically measures speed and direction.
Classification and statistics for up to 8 lanes. slowing vehicles and other kind of incidents. Reliably finds wrong way driving vehicles.
smartmicro Forward+ sensors perform counting, classification and deliver traffic statistic data. Up to 8 lanes, dual direction, can be covered. For all traffic objects it provides real-time position and speed vector plus other information.
Forward+ sensors deliver the highest speed accuracy available today, and detect stopped vehicles or wrong way drivers.
The products feature 4D/UHD ultra high definition detection for highest performance in congested traffic situations, with up to 450m detection range.
Installation and alignment is simple, using a pole mount position at road side on standard infrastructure (light poles or traffic signs).
This saves hardware- and installation cost. Smartmicro Forward+ is the only multi-lane traffic counting sensor which can be gantry mounted. Suitable for permanent or temporary installations.
Forward+ Incident Detection uses the integrated Event Trigger Module where zones of interest can be created, specific conditions can be defined (like a speed threshold, presence, a traffic object of a certain class); and this event can be assigned to a defined trigger message.
If, for example, a car stops in the middle of a road or at the hard shoulder the sensor can transmit a trigger message. Overall the Event Trigger Module is very powerful and flexible.
As an example, see the video in this section. Using UMRR-0C Type 40 3D/HD radars, one of smartmicro’s Korean customers developed a local Incident Detection System, which was certified by KICT and has been tested for >95% detection rate of pedestrians. The solution was implemented at multiple locations, among those highways in the mountains of Jeju Island or the Gwangan Grand Bridges in Busan, South Korea, as well as on several intersections across the city. Since the IDS went operational, the number of accidents and other incidents was significantly reduced. Potentially severe accidents were avoided and lifes saved.
Traffic Counting and Statistic
For fixed or mobile traffic counting stations, smartmicro radars provide precise volume and classification data for 4+1 classes, compute and accumulate statistical data including volume, occupancy, average speed, gap, headway and 85th percentile.
The smartmicro sensor is the only traffic Radar solution today to feature 4D/UHD - ultra high definition, and allows the most accurate lane specific speed measurement on the market.
It can be used in urban installations, to provide real-time data for smart cities, as well as for the traditional freeway counting stations and works for 8 lanes, two directions.
Looking along the road but not perpendicular as older traffic sensors, the mouning position of these new Radars are flexible, either on the road side, at the centre of a highway or on a gantry,
whatever sensor position provides the best coverage. No setback is required for roadside pole mount, existing infrastructure like light poles can be used.
Other than for older side firing radars which usually have occlusion problems and need a very high mounting position, moderate heights are sufficient here.
The wide field of view enables the user to define up to four measurement (counting) lines inside the field of view.
Since vehicles are tracked over a longer period when they drive in the field of view, the driving behavior of vehicles can be analyzed which helps mitigating occlusions and increases counting accuracy.
Moreover, changes in the speed can be monitored which are often an indication for possible incidents.
Wrong Way Detection
While wrong way driving is one of the most dangerous situations, such situations can be detected easily, reliably and very quickly using Smartmicro traffic radars.
Measuring speed very accurately, for both directions, for up to 8 lanes, the Radar's application software will find and report wrong way drivers immediately.
On/Off ramps can be monitored as well. The sensor can easily be integrated into existing or future warning systems.
Because of the modular application software design principle, the applications counting and classification, incident- and wrong way detection can be combined.
On freeway ramps smartmicro Radar sensors are used to adaptively control the freeway access from the ramp.
The sensor is capable of measuring the demand and the capacity simultaneously, it can count traffic and measure the speed.
For smart cities, one of the most important aspects is the optimisation of the traffic flow. For that, smart infrastructure sensors are required which can measure the traffic flow.
smartmicro sensors can do this very precisely and provide real-time object data which are (1) fed into local intersection controllers for direct local adaptive traffic control.
(2) The traffic data are transmitted to a traffic operation center (TOC) and allow an optimum traffic flow in a certain region or quarter or on a longer arterial, where the traffic flow is remotely (but automatically) controlled from that TOC.
(3) Real-time object data can now also be directly transmitted over a Car2X wireless transmission from an intersection to connected vehicles. This avoids accidents and protects vulnerable road users (VRUs)such as pedestrians and bicycle riders.
Reduced Travel Time
The city of Auckland, New Zealand, installed a system combining smartmicro's Multi Lane Traffic Radars, Bluetooth and Wi-Fi in order to smoothen the traffic flow from the city center to the airport.
The system already proved its worth as delays were decerased by 50% during peak traffic. ITS International magazine featured an article about the whole system and how it improved the passenger's journey in their March/April 2018 issue.

Queue Length Estimation
The Dutch cities of Amsterdam and Rotterdam have recently implemented a system to optimize traffic flow and safety.
A coordinated traffic management system consisting ofsmartmicro radar sensors and ARS T&TT’s Roadside System reliably and accurately detects real traffic situations like the intensity, queues and speed.
The state-of-the-art control strategy using radar sensors is not only cost-efficient, especially on long stretches of roads, it can also lead to a reduction of vehicle hours by up to 20%.
smartmicro introduces a brand-new system combining traffic management radar and V2X communication. In the future a mix of connected- (using V2X) and traditional vehicles will share the roads. Connected vehicles will communicate among each other and broadcast important information, improving the traffic.
smartmicro now introduces a solution that generates V2X messages to be received by connected vehicles based on real-time data acquired by fixed infrastructure traffic management radar sensors. Lane specific data, provided by smartmicro's 3D/UHD traffic management radar, are converted into appropriate coordinates (WGS84 standard), speed, heading etc. for all object classes (including pedestrians and heavy trucks). The system then broadcasts the corresponding V2X messages(in this case, to be more precise, Infrastructure-2-Vehicle, I2V messages).
This solution covers up to 8 lanes and features a detection range of up to 300 meters. At a typical fully equipped intersection, connected vehicles using the received V2X messages can ”see” around the corner into other legs of the intersection, and can pick up vulnerable road users (such as bicyclist and pedestrians), before they could even be detected by on-board sensors.
As V2X communication is rated as one of the key drivers for connected, autonomously driving cars, this system supports all V2X equipped vehicles where even non-connected vehicles, bicycles and pedestrians are covered.
