Dear Jean-Marie
Highways serve for transit traffic between important geographic points avoiding direct traffic through towns and villages. In the reference of above issue highways are equipped with own infrastructures which are designated only for theirs purpose like petrol station, parkings, restaurants, hotels, medical centres. This facilities are only for drivers which use highway.
