Transportation during the Qin Dynasty was standardized in several important ways to promote efficiency, facilitate trade, and enhance military logistics. Some of the key standardizations included:
-
Road Width: Roads were constructed to be the same width, which helped facilitate the movement of goods and troops across the empire.
-
Carriage Height: Carriages were standardized to be the same height, ensuring that they could pass under bridges and through gates without issue.
-
Road Tax: The imposition of a uniform road tax helped to streamline the revenue collection process and ensure that all subjects contributed equally to the maintenance of the road system.
-
Axle Length: The axles of carriages were standardized to the same length, which ensured that all vehicles could share the same roads without causing damage or hindrances.
These measures contributed to the Qin Dynasty’s ability to maintain control over its vast territory and improved the efficiency of trade and communication across the empire.
