Project Description
Caltrans Machine Learning Project for Trash Control Implementation
Caltrans Machine Learning Project for Trash Control Implementation
Caltrans is currently developing statistical, predictive and image recognition models with machine learning to assist with its trash control efforts statewide and in the SF Bay Area.
Specifically, these models are being used to identify trash hotspots, provide estimates of future trash collection and verify visual assessment results with image recognition.
