Predicting Traffic Accident Severity with Deep Neural Networks
This work addresses traffic safety by improving severity prediction, but it is incremental as it applies existing deep learning methods to a specific dataset.
The researchers tackled the problem of predicting traffic accident severity by applying deep neural networks to traffic accident data, achieving up to 92% accuracy in cross-validated classification results.
Traffic accidents can be studied to mitigate the risk of further events. Recent advances in machine learning have provided an alternative way to study data associated with traffic accidents. New models achieve good generalization and high predictive power over imbalanced data. In this research, we study neural network-based models on data related to traffic accidents. We begin analyzing relative feature colinearity and unsupervised dimensionality reduction through autoencoders, followed by a dense network. The features are related to traffic accident data and the target is to classify accident severity. Our experiments show cross-validated results of up to 92% accuracy when classifying accident severity using the proposed deep neural network.
