Seen suggestions about displaying reduced speed limits displayed on matrix signs on smart motorways. This is a great idea. Given the current surge in popularity of Artificial Intelligence, would it be possible to model and predict reduced speed limits at certain times of the day (think rush hour) and display these in the app? Obviously AI would not be able to predict accidents and other random events, but given that traffic information is already provided in the app, it should be possible to train a machine learning algorithm to predict speed limit changes based on real-world and traffic data.
