The M100BR radar bicycle detector incorporates an extremely low power, wide-band, fixed-position radar with aNano power radio. The compact in-ground sensor works using the same principle as any other radar. High frequency RF pulses are transmitted, reflected off a target object, and the return pulses are measured by a time-gated RF mixer. RF reflections are analysed to produce presence, distance and motion measurements. The detector incorporates a higher sensitivity radar design and a modified case with tabs to aid installation flush with the road surface.M100BR detectors are capable of detecting and distinguishing large objects from small objects. Detectors have a programmable detection range between 1.2m and 3m. The elevation of a detection zone is approximately 90 degrees and the azimuth is approximately 180 degrees.M100BR detectors can detect bicycles that are stopped at a stop bar and differentiate between a vehicle and a bicycle.The basic method to differentiate bicycles from vehicles is based on measuring the breadth of the vehicles returned RF signal. Bicycles field a relatively small breadth values while vehicles generate both small and large values depending on the location of the vehicle.radar bicycle detectionM100BR5

wireless vehicle detectionM100 SensorM100 sensors are sensitive magnetometers equipped with a lowpower secure radio transmitter suitable for in-road mounting. Sensors can be installed just below the road surface at 65mm or to a depth of 165mm enabling future road resurfacing to take place without the need to remove and redeploy the sensor. Installation requires a cored hole with a width of 100mm due to the compact size of the sensor and takes around 10-15 minutes per installation. Low powered detection signal technology combined with ahigh-quality internal 3.6v lithium thionyl chloride battery ensures an operational life of 10 years. The M100 uses 3-axis magnetic field sensing, with each sensor providing a detection zone of 2m in length by 1.3m width. Sensors must be deployed within 35m of an access point or repeater and communicates vehicle presence within 125 milliseconds allowing for real-time operation.M115 Repeater UnitsIn cases where one or more M100 sensors are installed out of the range ofthe nearest access point (over 35 metres), M115 repeater units can be used to provide a two-wayrelay,extending the range and coverage between the sensors and the access point. Repeater units have a maximum range of 200m fromthe M110 access point. Up to a maximum of three repeater units can be used in tandem to further extend the network.All repeater units are battery powered and require no external power supply or cabling. There are two variants of M115 repeater unit: the solar powered variant has a battery life over 10 years and is non-replaceable whilst the battery variant has a replaceable lithium thionyl chloride battery offering a 7-year life.Repeater units must be mounted on a convenient pole or other structure between 4.5 and 6m height with a direct line ofsight to both sensors and an access point. Repeaters can be mounted on the same pole or mast as another repeater oraccess point that is pointed in the oppositedirection as to communicate with sensors located within a different view.Both access point and repeater units provide a 120° field ofvision providing flexibility when planning and installing the system.M110 Access PointThe M110 access point maintains two-waycommunicationswith M100 sensors and M115 repeater units. It receives and processes detection data from M100 sensors, forwarding this onto the controller unit whilst transmitting a message acknowledgment back to thesensor.The access point uses a wired connection to relay the sensor detection data via a:• M120 interface card to a roadside traffic signal controller• M150 interface card into a MIDAS outstation• M160 interface card to a Vehicle Activated Sign (VAS)Theaccess point can be mounted on any roadside column orsignal head at a recommended height of between 4.5 - 6m that provides good signal coverage to sensors or repeaters.127

Available as short and long range, use of an antenna provides additional flexibility for applications such as MIDAS, queue protection orcomplicated junction layout. Short range antennas have arange of 200m back to an access point or repeater with a 35m range to sensors whilst a long-range antenna has a 400m range back to an access point or repeater alongside a 35m range to in-ground sensors.8Key Benefits
wireless vehicle detectionThe M100 wireless vehicle detection system uses embedded in-road sensors to detect the presence and movement of vehicles.The system provides a more reliable, lower cost and easier to install alternative to traditional inductive loops. The M100 system is used in many applications including traffic signal control, ramp metering, MIDAS, route safety schemes, bicycle detection and queue protection.Traffic Light Control and Bicycle Detection Thousands of sensors have been deployed in the UK and worldwide as part of a modern traffic signal system including over 1000 junctions deployed by Transport for London. The solution is traffic controller manufacturer independent and suitable for all Urban Traffic Control (UTC) systems including System D, MOVA and SCOOT.As with inductive loops, M100 wireless sensors can be located exactly where measurements are required whether it is at a specific through lane, turn lanes or entrance and exit ramps.Each M100 sensor is typically installed in the middle of a traffic lane where it will detect the presence and passage ofvehicles in that lane. Rapid installation of M100 sensors takes less than 1/5 of the time to install compared with a standard loop installation. By installing via a cored hole, installation of sensors eliminates the need for expensive and time-consuming slot cutting, trenching / ducting. Two or more sensors can be used and configured to replicate extended loops if required.Once installed, M100 sensors detect vehicle presence on the approach to each leg of a junction and feed this information toan M110 access point. The access point is connected to a M120 interface card in traffic light controller.9

No ducting or cabling is required between the in-ground sensors and the access point, saving on both cost and installation time.The M100 sensors and M115 repeaters are battery powered providing up to 10 years operational life. The M100 access points, repeaters, sensors and interface cards are all provided with a 5-year warranty.Signalised Junction10
wireless vehicle detectionMIDAS and Ramp Metering11
Ramp MeteringWith ever increasing levels of traffic on motorways, careful management of vehicle flow is essential for maintaining safety and avoiding congestion. Ramp metering is part of the answer: injecting traffic onto the motorways in a controlled manner that optimises capacity and integrates smoothly with the main carriageway.The M100 vehicle detection solution integrates into a ramp metering scheme with sensor detection points on both the ramp and the motorway network. Sensors measure the level of demand for traffic to join the motorway from the ramp and marries it up with data from the MIDAS network to “inject” traffic into the motorway flow with minimum disruption and improve driver journey time and experience.M150 MIDAS outstation interface card The M150 MIDAS interface card is manufacturer agnostic and is installed within the MIDAS outstation totranslate sensor detection data from an M110 access point.The M150 MIDAS interface card provides four detection channels suitable for two lanes; each comprising of an optically isolated contact closure relay for maximum reliability in both normally closed (n/c) and normally open (n/o) configuration and is switchable between different manufacturers of MIDAS outstation to give compatibility via a single interface card. Up to 16 interface cards can be daisychained together via the front panel connectors to support more sensors across multiple lanes.M100 sensors are installed two per lane at 4.5m spacing and mapped to their own individual channel so that upon vehicle detection the contact closure relay will close. The M100 wireless vehicle detection system can therefore be easily configured to replicate the way traditional inductive loops interface with a MIDAS outstation.wireless vehicle detection12

Identifying vehicles turningM100 systems have the functionality to alert drivers of an upcoming junction where a vehicle is turning from a side road with the potential to act as a hazard to vehicles travelling at speed. M100 sensors read vehicle occupancy at the entrance from the side road and activate a VAS sign via a smart junction controller to upcoming traffic, warning drivers of the potential hazard ahead. This increases driver awareness and encourages them to take precautionary action, ultimately reducing the likelihood and/or severity of an incident.Encouraging speed complianceEncouraging drivers not to break speed limits through enforcement is only effective to a level and can create the‘kangaroo’ effect of drivers slowing at certain points, notthe whole route. With two M100 magnetometer sensors located in advance of the stop line at a set of traffic lights, speed data can be processed within 125m/s and fed back tothe M110 access point connected to the traffic junction controller. If speed restrictions have been broken, the traffic signal controller issues a red light to bring the speeding vehicle to a standstill, prompting users to alter their behaviour over time and adjust to the correct speed for the area. Drivers will learn over time that driving in accordance with the restrictions is more likely to result in them having a smoother journey through the area and less chance of being stopped by a red light.Queue protectionVehicle congestion on key exits and junctions on motorways or A-roads can cause delays and a build-up of traffic. This canact as a stationary hazard to the fast-moving traffic behind and generate major journey time disruption at peak commuting times. Sharing information is key to giving motorists as much notice as possible of any upcoming delays or standstill traffic to increase driver awareness and ultimately improve route safety. The combination of queue detection with M100 sensors and the use of variable message signage highlights the upcoming hazard to drivers approaching the area and gives them the opportunity to act earlier in the event of traffic congestion on either the slip road of an upcoming exit or the road ahead.M160 Queue DetectionA M160 queue detection card translates vehicle detections from M100 sensors sent to it via the M110 Access Point into contact closure events which can be used to trigger actions such as activating VAS signs. Triggering contact closure events is the result of a pattern of vehicle detections matching user defined programmable logic criteria set by the user to determine what constitutes queuing or stationary traffic. This can be a mix of data points such as breach of speed, traffic volume or occupancy thresholds or timing around length oftime for which traffic appears to be slow or stationary.wireless vehicle detection14
