What was the greatest factor that facilitated the safe flow of goods along the Silk Road during the Renaissance?

Increasing demands for goods and establishing trading posts with Caravansaries.

Explanation:

The Silk Road is one of the oldest trade routes that linked China to the western world. The Silk Road stretched from China through India, then reached to Europe crossing the deserts. Some of the goods like tea, porcelain, silk, sugar, ivory, jade, furs, wool, spices, cotton, gold, and silver traded. The increasing demand for goods during the Renaissance period led to the profits for traders. Compass, gun powder and other material reached Europe through this silk road.

Silk Road caravans used pack animals such as camels as they were able to travel in desert regions and horses. With no authority to provide maintenance, the roads were poor condition. Robbers were common. Trading posts or towns lay at regular distances of the Silk Road. Travellers inns set up known as caravansaries, where the traders (caravans) could take rest at night, and resupply their food. To protect themselves, traders joined together to travel long distances.
