Why we don't have smart intersections in our cities? Many municipalities think this is an expensive solution or that the solution is too complex. This is fortunately not true anymore. In this webinar, we will introduce a new FLOW edge video-analytics device TrafficXRoads – a real game-changer in the industry of collaborative sensing technologies for dynamic traffic control and collection of traffic data. Our sales director Tomáš Šárocký and business manager Pavel Fojtík will showcase there the basic characteristics of the unit capable of processing at least 6 camera streams in real-time, how to set it up in real scenarios, and share experiences from real installations.

1. Basic characteristics of the TrafficXRoads unit

2. How to set up TraffixXRoads in real scenarios

3. Recommended cameras, camera positioning, and available accessories

4. Possible limitations of video analytics

Q1: How many cameras can you connect to the unit?

A: With FLOW version 1.13 or higher installed, the unit can analyze up to 6 camera streams at ~15 FPS. It is possible to connect any camera to the unit that provides RTSP stream h264/h265. The current video-analytical engine is not optimized for fisheye cameras (high distortion cameras). We recommend cameras with technology for the improvement of the night image quality for example the AXIS P1455-LE(3-9mm) with the Light Finder technology.

Q2: What are the available data outputs and other outputs?

A: The unit support UDP sinks, REST sinks, and Webhooks. For connectivity with traffic controllers, we recommend using the UDP sinks via ETHERNET cable for minimum latency. If the traffic controller does not support data interfaces, it is also possible to communicate via a physical I/O relay interface. The unit also supports communication via an SDLC converter.

Q3: Is it possible to configure the unit remotely?

A: Yes, it is possible if the unit is connected to the internet or other network within which you need to do the configuration. The unit has its own IP address and can be configured using the FLOW Insights desktop application. The application allows for minimizing of the data requirements of the communication which makes configuration possible even when using slow data connections. The unit supports customer VPN networks for example WireGuard and SoftEthernet.

Q4: Can the unit collect traffic data?

A: Yes, the unit also works as a data collector. The format and frequency of the data collection is fully configurable via the FLOW Insights application. It is also possible to save statistical information and register different traffic events. The available data includes for example vehicle counts, average speeds, OD matrix, histograms, and more…

Q5: What are the detected types of objects and what categories do you detect?

A: The currently supported object categories are car, light vehicle, heavy vehicle, bus, motorcycle, bicycle, and pedestrian. We are working on adding additional categories in newer versions.

Q6: What is the operational temperature and how reliable is the unit?

A: The unit contains the industrial version of the powerful AI processor Xavier NX. This allows for deployment in working conditions from -20°C to + 65°C and extreme reliability. Some units were also cold-start tested in -40°C in a climate chamber and performed without any issue. In case of overheating the unit automatically reduces its processing with underclocking to prevent damage to the HW. The units are designed for installation inside traffic controller box for example on a DIN rail.

The era of new, reliable, and affordable video analytics solutions is here allowing the creation of truly smart intersections that can adaptively control traffic based on a variety of real-time parameters including speed data, queue length, classified counts, OD matrix or relational positioning such as cars and pedestrians for the protection of vulnerable road users while gathering valuable traffic statistics.

In this webinar, you have learned about the new video analytics solution for adaptive traffic management the TrafficXRoads unit that supports up to 6 cameras to create "virtual inductive loops" and gather a variety of traffic data. We have shown you how you can set up the TrafficXRoads unit in real scenarios and we also went over recommended cameras, their positioning, and possible limitations of the solution. We hope enjoyed this webinar!
