Systems and equipment for fire and smoke control in road tunnels

This report complements the PIARC report published in 1999 "Fire and Smoke Control in Road Tunnels". After a presentation of the basic principles of smoke and heat progress at the beginning of a fire, the report presents the safety concepts for tunnel fires. It draws the lessons from the fires which occurred in the Mont-Blanc, Tauern and Saint-Gothard tunnels. The role of transverse and longitudinal ventilation is presented. The question of emergencies exits and escape route is addressed in detail, [...]

Traffic Incident Management Systems used in Road Tunnels

This report mainly identifies incident detection and verification devices being used in tunnels to provide operators with the information required to implement response scenarios, devices and systems being used by operating agencies to respond to incidents, and communicate with motorists within the tunnel.

Containment Devices on Road Bridges

Drafted by the PIARC Technical Committee on Road Bridges, this report deals with the study of equipment on the outer side of road bridges, i.e. located between the carriageway and the free edge, whose function is to ensure safety of users and frontagers. The report has used the replies to a survey received from the following countries: Australia, Austria, Belgium, Canada, France, India, Israel, Italy, Japan, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, United States, United Kingdom, [...]

Road Design and Traffic Operation Guidelines to aid the Older Motorists

Studies show that the number and percentage of older people in general, and older drivers in particular, are growing rapidly. By the year 2025 people aged 60 and over are expected to account for about 24 percent of the European population, 22 percent of the Northern American population, and almost 14 percent of the world population. This increasingly older population is reflected in a corresponding increase in the older driver population. Studies in Europe and the United States indicate that [...]

CD-1303 - Road Safety Manual

This manual, written by experts of the World Road Association (PIARC), is a basic reference for all transportation engineers concerned about road safety problems. In more than 500 pages, the work presents, in an easy-to-read, easy-to-consult format, an up-to-date summary of the accumulated knowledge of the last several decades. The work is divided into four parts. The first part introduces the reader to the road safety field. The second part describes a complete safety analysis process (from [...]
