Technical Reports Road network operations
This page lists technical reports of PIARC in the field of road network operations. These publications are classified chronologically.
State of the Art in Monitoring Road Condition and Road / Vehicle Interaction
This report is a follow-up on the report "State of the art in monitoring road condition" which was finalised in 2015 (PIARC reference 2016R17EN). The 2015 report summarises the then current state of the art regarding the collection of road condition and road/vehicle interaction data, providing an overview of current practice and emerging technologies. The current report is an update of some chapters due to new findings as a result of recent research. It also discusses technologies in the development [...]
Connected Vehicles - Challenges and Opportunities for Road Operators
The deployment of Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communication, also known as cooperative intelligent transport systems (C-ITS) is speeding up in many developed countries. For example, Japan has already an operational system at national level, the United States are considering a law mandating dedicated short-range communication in new cars, and the European Union has developed a strategy aiming at massive deployment from 2019. These technologies involve many opportunities [...]
Electric road systems: a solution for the future?
It is looking increasing likely that electric vehicles will play a major role in the future of road transport. While commercial electric vehicles exist their uptake has been limited due to high purchase costs, limited battery range, and a lack of charging convenience. Furthermore, while developments are underway, electric and hybrid drive trains are yet to be efficiently integrated with heavy goods vehicles (HGVs). A novel way to overcome such challenges are Electric Road Systems; a branch of technologies [...]
Investigating Unpredicted Infrastructure Failure
This report is an outcome of PIARC mechanism for Special Projects, which is PIARC instrument to respond quickly to emerging issues for PIARC member countries. This report provides a review of 15 Unpredicted Infrastructure Failure (UIF) case studies that have been collated from around the world. For the purposes of the report UIF is defined as: instances where failure1 occurs on an asset that is considered in good condition and is well maintained The case study data from our interviews and [...]
Uses of ITS including consideration of planning for future improvements, upgrades and the economy
Economic growth typically results in an increase of both freight and passenger traffic. This generally compounds the problems in transportation systems. ITS technologies have been widely used to mitigate many of these transportation challenges and will continue to play an increasingly important role in securing the future of sustainable mobility. Sections 1 and 2 of this report deal with the primary factors that contribute to a sustainable transportation system. It also explores the ITS services [...]
