PIARC Online Manuals
PIARC has published three interactive electronic Manuals, which are available online free of charge. These compendiums address Road Safety, Road Network Operations and ITS, and Tunnels.
Road Safety Manual
The new Road Safety Manual (RSM) is designed to help countries at every stage of infrastructure development to fulfil road safety objectives. It includes new thinking on road safety and offers a clear argument on why adopting a Safe System approach is crucial for your country.

RNO & ITS Manual
This electronic manual on RNO & ITS is a comprehensive, regularly updated handbook helping practitioners to alleviate road congestion. Road Network Operations (RNO) concern methods that contribute to safer and more efficient travel for road users. Intelligent Transport Systems (ITS) concern a wide range of services that use information and communications technology that can improve transportation and mobility.

It includes all reports and articles produced by the Technical Committee on Road Tunnels Operations since 1995.
