Project Objective
The goal of this project is to create a method for estimating the statistics for vehicle count/traffic flow into one intersection in New York City. As an example, record videos of the northbound traffic on Amsterdam Avenue, as vehicles are entering the 120th St./Amsterdam Av. intersection. Using YOLOv3 deep learning model, detect and count vehicles as they approach/enter the intersection from south, making sure that there is no double-counting. Use 180 second long video fragments (approximately two traffic light cycles), and repeat up to half a dozen times a day, for a number of workweek/weekend days during the same times of each day. Compare the vehicle count (traffic flow) as a function of the time of the day. Utilize NVIDIA DeepStream deployed on COSMOS GPU compute servers to run the model. The method should be generalizable/expandable to any direction of vehicle movement, when appropriate camera views are available.
Week 1 Activities
- Get ORBIT/COSMOS account and familiarize oneself with the testbed procedures
- Learn about YOLOv3 deep learning models for object detection
- Read about NVIDIA DeepStream
- Explore the image (set of computing tools) available on COSMOS, which uses DeepStream and can deploy YOLOv3
- Brainstorm about vehicle counting/traffic flow estimation methodology
