This electronic manual on Road network operations & intelligent transport systems 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. This includes techniques such as traffic incident detection, incident management, traffic control (urban and inter-urban), traveller information (pre-trip and on-trip), public transport priorities, electronic payment and travel demand management techniques.

Intelligent Transport Systems (ITS) concern a wide range of services that use information and communications technology that can improve transportation and mobility. They have become a core discipline in Road Network Operations, varying from country to country in levels of take-up and local applicability. This website offers guidance on the effective use of ITS in Road Network Operations based on practical experience in many countries.
