A Quantitative Approach to Trash Control Implementation

Date / Time:
Tuesday, Oct 16 1:35pm to 2:05pm
Location:
Meeting Room 1-3 (Lower Level)
Track / Session:
Trash Track / Trash Assessment and Tracking
Description/Abstract: 

Caltrans is developing its implementation plan to comply with the statewide Trash Provisions (Water Code Section 13383 Order) issued by the State Water Board and evaluating new technologies such as machine learning, image recognition and data analysis to assist with developing the plan.

Through the use of these technologies, Caltrans aims to more effectively assess trash levels, plan work and monitor progress. Conventional methods alone for assessment and monitoring are time and cost prohibitive given the extensive amount of right-of-way statewide. As a result, these new technologies in combination with manual verification and visual assessment may offer a solution.

The goal of this quantitative approach will be to reduce human error during analysis, produce numerical datasets for comparison and develop a data model for improving the planning, implementation and monitoring of trash control measures.

This presentation is intended to provide the audience with an overview of this approach and share knowledge obtained through the initial evaluation of new technologies.
