Learning from data is a very attractive alternative to “manually” learning. Therefore, in the last decade the use of machine learning has spread rapidly throughout computer science and beyond. This approach, supported on advanced statistics analy
Introduction: Transportation systems play a fundamental rule in nowadays society. Indeed, every developed or in development country had invested and keep investing to build a complete, safe and functional transportation network. Now, the main concern
