  We address the vehicle detection and classification problems using Deep
Neural Networks (DNNs) approaches. Here we answer to questions that are
specific to our application including how to utilize DNN for vehicle detection,
what features are useful for vehicle classification, and how to extend a model
trained on a limited size dataset, to the cases of extreme lighting condition.
Answering these questions we propose our approach that outperforms
state-of-the-art methods, and achieves promising results on image with extreme
lighting conditions.
