The Umayyad and Abbasid rulers made use of existing road networks which provided routes for military forces and administrative officials traveling throughout the Islamic world.
The roads were also useful for merchants, missionaries, and pilgrims. The roads were so efficient that by the eleventh century, Muslim rulers in Egypt regularly imported ice from Syria to Cairo.
Five camel loads of ice were delivered weekly to cool their food and drink. The primary means of transportation was the Camel, which could handle desert heat and carry relatively large loads.
Along with camel transport, caravanserais, inns for caravan merchants and areas for animals to be rested, fed and watered, developed along the roads.
From the Chinese, the learned the use of the Compass; from Asian and Indian merchants, they learned the use of Lateen (triangular) sails which increase maneuverability.
From the Mediterranean, they learned the use of the astrolabe, which enabled them to calculate latitude.
