Technical Reports Road network operations
This page lists technical reports of PIARC in the field of road network operations. These publications are classified chronologically.
Setting Credible Speed Limits - Case Studies Report
This report of case studies on the topic of speed limits includes a series of implemented countermeasures or experimental proofs of concept to help improve the road safety in a specific location or area. PIARC didn´t work on specific speed issues in the past periods, therefore this report also contains a short theoretical introduction concerning the role of speed in road safety and the importance to set speed limits that are credible for road users. Credible is in general an individual task and [...]
Big Data For Road Network Operations
Currently, several technological developments are influencing the day-to-day work of road network operators. Automation, internet of things (IoT), smart systems, mobility services, artificial intelligence and big data are aiming to improve traffic operations and enhance mobility. Among these technologies, big data and big data processing technologies are key enablers for all other technologies. Big data has the potential to influence the whole value chain in the road transport sector. The scope [...]
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 [...]
