Automated Crowd and Wait Time Estimation for the Silliman Acorn
Cutter Renowden ‘28A privacy-conscious machine learning system to estimate occupancy and predict wait times in the Silliman Acorn. The system does not use facial recognition and instead counts the number of people present in the space.
The model runs on a Raspberry Pi with an attached camera module. To protect privacy, faces are obfuscated using Gaussian blur, no live video stream is shared, and no image or video data is stored. The system transmits only aggregate information — estimated occupancy and predicted wait time — to a public-facing website.
A ridge regression model trained on collected wait-time data predicts expected delays from observed occupancy, letting students assess crowd levels before arriving. Coordination with Silliman facilities is already in place for deployment.
