Description

Private sector parties, public sector and knowledge institutions jointly developed a shockwave traffic jam service based on innovative Talking Traffic techniques on the A58 between Tilburg and Eindhoven. This shockwave traffic jam service consists of a smartphone app where a large group (1000+) of participating motorists are given personal in-car advice about the ideal driving behaviour and ideal driving speed to prevent shockwave traffic jams.

Results/Lessons Learnt

What is a shockwave traffic jam? Shockwave traffic jams are caused by shockwaves that are the result of driver behaviour on busy roads. If one driver has to brake suddenly, this could result in a chain reaction of suddenly braking traffic. Shockwave traffic jams are caused by ‘stop-and-go traffic’, not by a lack of road capacity in itself. The shockwave traffic jam service consists of a smartphone app where participating motorists are given personal in-car advice about the ideal driving behaviour and ideal driving speed to prevent shockwaves. Basis for Talking Traffic In this project the technical, organisational and process-based challenges of the collaboration between private and public sector are becoming clear. This collaboration is organised by Pre-Commercial Procurement (PCP). This stimulates private sector parties to develop innovative techniques and it sets the right conditions for free market processes. Open architecture A group of Dutch companies in close cooperation with national and regional authorities have developed a fully operational cooperative infrastructure based on a service independent high level architecture (HLA), clearly specified interfaces supported by a wide range of suppliers while using European standards (ETSI, CEN). This is an architecture with measures in place to protect drivers’ privacy and system security (PKI). A setting that has already proved to be suitable for realisation of additional use cases such as Road Work Warnings. Real life test environment The motorway A58, part of the international ITS Corridor from Vienna to Rotterdam, is fully equipped with WiFi P infrastructure between the cities of Eindhoven and Tilburg. This project forms part of Beter Benutten, with the province of Noord-Brabant developing a real life test environment (on a common highway during daily traffic) where cooperative technology can be tested in real life traffic situations. In April 2016 the shockwave traffic jam service is upgraded to a cooperative real-time service which makes V2V and I2V possible. The service uses data and intelligence which is provided by other vehicles and/or road side systems. On the long term the shockwave traffic jam service is the basis for cooperative services and Talking Traffic in the Netherlands and Europe. Talking Traffic techniques will be tested on the Dutch motorway A58 in 2016. The final report will be presented in 2017. Scale-up The A58 architecture and infrastructure is capable of delivering on interoperability and scalability. Further development and testing of cooperative systems in the Netherlands and Europe remains a prime goal for the coming years, while being integrated in the above mentioned hybrid test facilities between Helmond and Tilburg.
