The World Road Association (PIARC) has recently launched the electronic manual on Road Network Operations & Intelligent Transport Systems. The manual is a comprehensive, regularly updated handbook helping practitioners to alleviate road congestion, a major worldwide issue that directly affects the economies of many nations.

Road Network Operations (RNO) concern the methods at the disposal of road authorities and highway infrastructure operators that contribute to safer and more efficient travel for road users and for society as a whole. Intelligent Transport Systems (ITS) concern a wide range of services that use information and communications technology that can improve transportation and mobility.
