CalTrans Rapid Trash Assessment Method
Latest News
Caltrans has completed an initial statistical model for identifying trash hotspots and currently developing predictive and image recognition models. These models will be improved with data collected from trash control implementation and provide insight on how and where to deploy resources.
Project Description
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.

Image Recognition
Initial results from training dataset which will be used to evaluate visual assessment photos
Predictive Modeling
Regression algorithms compared to evaluate the best one for a predictive model:
Correlation Analysis
Relationship identified between trash volume and labor/materials/resources (red = high, teal = low):
Trash Collection Efficiency Rates
Clustering algorithm used to identified efficiency groups within high trash corridors (red dot = center of group, shades = groups):
