Watch back the Webinar: How to Use 360° Radar to Achieve Vision Zero

What video management systems do you integrate with?
ClearWay integrates with Milestone XProtect, Genetec Security Centre and IndigoVision.

What is the range of the radar and can the system cope with curving roads?
The operational range of our 360° radar on an open highway is 250m (radius) and 500m in total (diameter). The system is well-suited to curving roads—radars are typically mounted on the outside of bends to maximise line of sight and placed closer together to ensure full coverage.

Can you define more active areas within the supervision range like the main carriageway and the slip road?
Yes, the system allows for the definition of separate zones within the radar’s coverage area. We can differentiate between main carriageways, ramps, and slip roads, and configure alarms to trigger independently for each zone. This enables targeted monitoring and alerting based on the specific area of interest.

Is the traffic data robust enough to be used for other management strategies, such as ramp metering?
Yes, the traffic data provided by the system is reliable and accurate enough to support advanced traffic management strategies, including ramp metering. In fact, the solution is already in use for ramp monitoring on the Transmission Gully Motorway in New Zealand, demonstrating its effectiveness in real-world applications.

How would the radar system integrate with other 3rd party cameras?
We have a list of 50+ cameras that we are integrated with already, however we can integrate with any ONVIF compliant camera. At Navtech we have our own in-house software team who can support camera integration.

How do you manage interference issues, such as avoiding duplicate alerts?
ClearWay manages alarms on a section basis. This means that even if a section has overlapping radar coverage and two separate detections occur, ClearWay will only raise a single alarm. Since both detections fall within the same defined section, the system recognises them as part of the same event and avoids generating duplicate alerts.

Does ClearWay use Machine Learning tools?
ClearWay is primarily algorithm-based. While the system does have some machine learning capabilities, these are not typically deployed. We’ve found that many road operators are cautious about adopting machine learning and AI-driven tools, so our approach focuses on reliable, rule-based detection.

Does the detection system work even in heavy snow?
Yes, the system is capable of detecting in heavy snowfall and also has the capability to adapt to accumulating snow on the ground.

What’s the mean time before failure (MTBF) of the radar?
The radar has a mean time before failure of 12.8 years, indicating long-term reliability even in demanding environments.

How many different vehicle classifications can the system separate vehicles into?
We classify vehicles by length. Our radar measures the length of each vehicle and using this information the ClearWay system can classify up to a maximum of five classification bins e.g. 1-5m, 5-10m etc.

Is there a minimum mounting height for the radar unit? If mounted lower, how does that affect range and visibility?
Yes, there is a recommended minimum mounting height. On open highways, we typically install radar units at around 4.5 metres above the road surface. Mounting below this height can increase the likelihood of occlusion from passing trucks as radar is a line of sight technology. At 4.5 metres, we maintain good coverage by the radar beam and the ability to see over large vehicles.

In tunnels, installation height is more constrained by the structure. However, we generally wouldn’t mount lower than 3 metres above the road surface. Since tunnels usually have fewer lanes and are more controlled environments, occlusion is less of an issue compared to open highways.
