The Roman Empire faced several challenges in managing a vast territory, particularly regarding the safety and comfort of travelers. To help travelers find their way, the Romans installed milestones along the roads, which served as guide posts indicating distances to towns and other important information. For safety, they deployed military units to patrol the roads, ensuring that travelers were protected from potential dangers. Additionally, to provide rest and sustenance, the Romans constructed mansio, which were designated stops offering food and lodging. This comprehensive approach helped facilitate travel across the expansive Roman Empire.
