    This work proposes a holistic method for highway traffic video classification based on vehicle crowd properties. The method classifies the traffic congestion into three classes: light, medium and heavy. This is done by usage of average crowd density and crowd speed. Firstly, the crowd density is estimated by background subtraction and the crowd speed is performed by pyramidal Kanade-Lucas-Tomasi (KLT) tracker algorithm. The features classification with neural networks show 94.50% of accuracy on experimental results from 254 highway traffic videos of UCSD data set. Read Less

SPPRA'2013 Paper Presentation
Example of crowd properties extracted from six videos with three distinct traffic patterns (light, medium and heavy). In this video two holistic properties are extracted: avg. of crowd density and avg. of crowd speed.
The features are classified with a multi-layer perceptron (MLP) using RPROP algorithm for training, and a sigmoid function as an activation function and four hidden neurons.
Normalized features extracted from UCSD traffic videos
MLP evaluation in four test trials varying the training algorithm (TA), activation function (AF) and number of hidden neurons (HN)
Cumulative confusion matrix of the proposed system using MLP network with best configuration.
