Experiences and recommendations for the development and use of dynamic, environmentally sensitive traffic management systems
Clean air plans are intended to help improve air quality in particularly polluted regions in accordance with legal requirements. A special focus here is on road traffic as one of the main causes. Dynamic, environmentally sensitive traffic management (ETM) systems enable the targeted activation of measures to improve air quality in line with the current situation. On behalf of the Federal Highway Research Institute (BASt), the effectiveness and impact of existing ETM systems was investigated on the basis of real data. The results show advantages of temporary needs-adapted measures compared to permanently activated ones. Depending on the level at which the immission limit values are exceeded, the local situation and the meteorological and traffic conditions, ETM systems can lead to compliance with the limit values in subsequent years. The results of the project were summarised in recommendations for the construction and use of ETM systems and measures depending on the local and immission boundary conditions.
