Cooperative Architecture Shockwave jams (Dutch motorway A58) is suitable for multiple C-ITS use cases

22-12-2015

The Netherlands wants to head the field in the area of smart mobility. Active public support of private innovations and international cooperation in the field of C-ITS are prime goals. Learning by doing in a living lab is the way to go. In the projects Shockwave jams on the A58 (Spookfiles) and ITS Corridor, for example, private enterprises and road managers are developing and testing advanced technology in combination with new ways of traffic management and new forms of cooperation between public and private parties. A demonstration on 15 December 2015 showed that the A58 C-ITS architecture and infrastructure is suitable for the deployment of multiple use cases.

In the test, four private parties had a testdrive from Eindhoven to Tilburg (round-trip) on the motorway A58. All vehicles successfully received the Road Works Warning (RWW) messages which were sent by every roadside unit. The messages, created by three of four parties, were compliant to a predefined profile created by the Dutch ITS Corridor project team of the national road authority (Rijkswaterstaat). Next to the shockwave mitigation service, this is the second use case that has proven to be fully functional using the same architecture as the shockwave use case. The A58 project partners Siemens, Vialis, Technolution and V-Tron were successfully capable of preparing and executing this test in two weeks’ time.

The test confirmed that the A58 architecture and infrastructure is suitable for rapid and straightforward deployment of multiple use cases. In addition, every road authority is capable of sending traffic management messages to different service providers that can be received and interpreted by all service providers. All test drivers received these messages correctly, independently of the service provider responsible. This important test demonstrated the A58 architecture is capable to deliver on interoperability and scalability.

 

Agreements needed on traffic situational interpretation

The demonstration also showed the traffic situational interpretation of each use case deployment needs improvement. The Road Works Warning test showed variations in interpretation and presentation in the different vehicles. For example, the exact location where the emergency lane is allowed to be used by regular traffic, became subject of discussion during the evaluation. Another example is the numbering of the lanes, either inside out or outside in. These aspects need further international coordination and agreements.

 

Shockwave jams A58 (Spookfiles) project

Developing and testing of cooperative systems in Netherlands and Europe is a prime goal of the shockwave jams A58 (Spookfiles) project. Its ready to use infrastructure is therefore fully ETSI ITSC compliant; its architecture is service and use case independent. Open interfaces have been defined and described. Therefore, the architecture can be used for any party wishing to connect, test and improve their ITS services.

 

The Netherlands testing land C-ITS

The highly advanced and dense road infrastructure as well as the high use of smartphones, dense 4G coverage and many public initiatives give many advantages for developing, testing and deploying C-ITS in The Netherlands. The Netherlands have invested in well-established knowledge clusters in the automotive and technology fields. High standard facilities create a favorable developing, testing and deploying environment.

 

Province of Brabant is pioneer on testing C-ITS

The province of Brabant facilitates the living lab to develop, test and put into practice new techniques and services. That’s why Brabant is the commissioning party of project shockwave jams on the A58 (Spookfiles). This project is part of the “Optimising Use” (Beter Benutten) programme of the Ministry of Infrastructure and the Environment. ITS activities in the Optimising Use programme are targeted towards improving traffic flow on the road network, in an urban and inter-urban environment. Adding ‘intelligence’ to mobility shortens door-to-door journey times. Private and public parties and knowledge institutions are working together on the deployment of cooperative ITS.

Thirty-four interconnected WiFi-p (802.11p) beacons cover both A58 carriage ways between Tilburg and Eindhoven, serving cooperative vehicles traveling east and west. First users will soon be guided by the cooperative shockwave mitigation service. The successful demonstration helps bringing the ITS Corridor another step closer to its ultimate objective: an international cooperative corridor between Vienna, Frankfurt and Rotterdam. The A58 section between Eindhoven and Tilburg is the first part of this Corridor where 802.11p based services are tested by consumers in a real traffic situation.
