Impacts of cooperative systems and relevance for cities

Last year the European project DRIVE C2X finished. This project carried out research on cooperative systems. Some of these systems are relevant for cities and might in the future be used in urban areas, therefore this email contains some of the results and provides a link to more information.

The DRIVE C2X project provided a Europe-wide assessment of cooperative systems through field operational tests. More than 750 drivers tested eight safety-related cooperative functions. The project provides proof that cooperative systems work and demonstrates a positive impact on safety, travel efficiency and the environment. Some results:

  • In-Vehicle Signage (IVS) is a system that shows speed limits in the vehicle continuously. Drivers reacted to this information by reducing their speed in most cases. Assuming a 100% penetration rate, IVS would reduce on average 23% in fatalities and 13% in injuries. Significant effects are shown for environment and traffic efficiency.

  • Weather Warning (WW) would lead to 6% less fatalities and 5% less injuries.

  • Green Light Optimized Speed Advisory (GLOSA) indicated significant effects for both the environment and traffic efficiency. Drivers reacted to the information by reducing their speed in most cases. This system is especially relevant for cities.

  • User acceptance is high with nine out of ten test users welcoming the cooperative systems.

On the website of DRIVE C2X more information can be found: http://www.drive-c2x.eu/project. Under ‘publications’ the publications of the project can be found. The press release and presentations given at the final conference give a nice summary of the results. 

Are cooperative systems a topic you know something about, or want to know more about? Do you take them into account when making future plans for your city? Feel free to react to this item.
