Background and problem definition

Air pollution has become an increasingly serious problem especially in urban areas, where large numbers of people are particularly vulnerable. This is because of the negative impacts of pollution on both public health and the environment. Vehicular emissions are considered the major contributor to the deterioration of air quality in urban centers. Compared to polluting industries, vehicles can not simply be relocated to remote areas and therefore they have to be managed to help reduce emissions.

The European EU directives contain threshold values for the emission of various pollutants. Plans of action must be taken where these threshold values are exceeded, which already happens in many Dutch municipalities. Without further measures these situations will just worsen.

Methodological approach

The main goal of this project is to improve the local air quality in an urban corridor using integrated road-vehicle systems. The intention is to evaluate to what extent integrated road-vehicle systems can contribute to improving the air quality in urban environments. Special attention will be given to the use of in-vehicle systems (i.e. driver support systems) in order to show the value that such systems add. Examples of these systems are Adaptive Cruise Control (ACC) and Intelligent Speed Adaptation (ISA). In particular, the project will investigate the cooperative implementation of these systems, in which assistance is provided from both the roadside and other vehicles.

Integrated road-vehicle system

To achieve this goal, the approach will start with the development of an indicator for the momentary local air quality. Then develop an integrated algorithm for influencing the traffic via roadside and in-vehicle systems. The operation of the algorithm will be studied on the basis of a traffic model. Finally, the system will be demonstrated in an urban corridor using a test vehicle.

Expected practical and scientific results

Simulation frameworkA simulation framework will be developed to investigate the impact of a cooperative traffic management system for environmental purposes.

The project is partially funded by Vialis traffic system manufacturer who will integrate the results of the project into a real-world pilot site. This is in a connection with the Dutch test site for integrated vehicle-road systems which is being realised in the context of the new European CVIS and SAFESPOT projects.

Scientific and societal relevance

The project will give a better understanding of the dynamic relationship between air quality and traffic and the possibilities to influence it. This will form the basis for identifying the possibilities to influence the road traffic so as to safeguard local habitability.

The two main social objectives to which the project is expected to contribute are improving the quality of life and health, and protecting the natural environment. The implementation of the project in the future will help the cities to meet the European and national legislation on air quality. This will save money since meeting the limit values could cost the Dutch government roughly a billion euros which is considered socially unacceptable.
