Build Your Own Traffic Monitor
Visit the Getting Started documentation for recommended hardware and software installation before you can begin capturing roadway data. The traffic monitor open-source software supports multiple configurations of the sensors.
Fully Customizable
Here are some sample sensor configurations and the data it collects:
- The camera + AI co-processor is the lowest cost and will give you object detection and direction.
- Add a radar in addition to the camera + AI co-processor for speed measurement in addition to object detection and direction.
- Include an environmental sensor to also measure air quality, gases, particulate matter, noise, temperature, and much more.
- (future feature) Install only the radar for the most privacy-conscious built that will be capable of basic object detection, speed, and direction.
- Add in an additional camera to monitor a second direction using the same AI co-processor.**
** The traffic monitor software is capable of supporting potentially any number of cameras either connected directly or via a local feed on the same AI co-processor for monitor multiple directions or any other configuration (see recommended hardware > cameras for more details). The TM software also has support for up to four (4) radars directly connected and paired in any pattern to the cameras.
