Video Analytics Test Bed

Challenge 

Creating a functional testbed utilizing traffic signal equipment for testing new video analytics systems with reduced risk. 

Solution 

The test bed created at the Translab allows for a standard 342LX traffic cabinet mounted inside of the Translab property to receive inputs from various intersections and control a simulated intersection. The system can use any form of detection (video, radar, lidar, etc.) and send inputs into the controller, which then transfers outputs to a intersection simulation box. This allows for real world inputs, outputs, and infrastructure, without directly impacting the travelling public.  

Result  

• Safety, because the outputs are not controlling a signalized intersection, a failure will not impact the travelling public at all.

• Efficiency, since this system is collecting data from multiple intersections, some systems can be installed at a single location while testing use cases throughout the region.

• Cost effectiveness, this system was designed to test new products in the most efficient way possible, while also trying to accommodate the various environments throughout Caltrans. With this system, material can be installed once and tested with data from various sites, rather than having to install the same units at different locations.
