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 [...]
Cooperative Vehicle Highway Systems
We can consider that the most recent developments of the vehicles are: the massive deployment of sensors, actuators and computers allowing to develop a kind of "vehicle and transport system intelligence"; their ability to communicate among themselves or with the infrastructure through the concept of cooperative systems; the introduction of electric motor combined or not with thermal motor: hybrid vehicles or full electric vehicles. All these changes are beneficial for both the car manufacturers, [...]
Road network management for improved mobility
It is useful to review the term "Intelligent Transport Systems (ITS)" in this report. According to the PIARC ITS Handbook, ITS is a generic term to mean integrated communications, control technologies and information processing systems for transport applications. However, in this report, we consider the need to define "ITS" as Intelligent Systems for improving mobility using integrated communications, control and processing technologies of information to meet smart objectives and goals (specific, [...]
