From the Saxon mail service columns and the survey of the Saxon postal routes
In particular, you will find interesting information about the Saxon postal milestones, which Augustus the Strong (1670-1733) let set up, but also about the surveying of Saxon roads, which took place at that time with measuring carriages and carts.
In the eighteenth century, the first comprehensive European traffic guidance system was built in the electorate of Saxony, following Roman prelims on the former regional transport routes - the Saxon postal milestones. Adam Friedrich Zürner (1679-1742), declared distances information as hours (1 hour = 4.531 km), it was the basis for the survey of the country. The magnificent columns, which can be found in many places in Saxony, still remind us of the elaborate project that August the Strong took.
