Kurzbeschreibung (Abstract)

This article describes some fundamentals for an environment-responsive traffic control. Itstarts with a brief description of the needs to consider environmental aspects in urban trafficcontrol, focusing on noise, particular matters (PM), and nitrogen oxides (NOx). Respectivecurrent regulations by law in Europe and Germany are explained. Comparing the regulationsfor the improvement of air quality and for noise reduction, important similarities anddifferences are pointed out.In the next section, the idea of a dynamic traffic control is introduced, which takes intoaccount not only the traffic situation, but also the current environmental situation.Systematically, the different options of dynamic measures to influence traffic volumes andtraffic flow are being analyzed and assessed for their general potential to improve theenvironmental situation while avoiding unnecessaryrestrictions for motorized traffic. An overview on measures is given whichhave been applied so far to improve the environ-mental situation, concentrating on traffic control measures. E.g. this includes approaches tooptimize traffic signal control, restrictions forheavy vehicles to pass certain parts of thenetwork, “environmental zones” (Umweltzonen), and speed limits.Furthermore, different methods to assess the potential of traffic control measures as a basisfor a situation-dependent selection of measures are described, especially regarding thequality of their results (accuracy, time resolution, and spatial transferability). Concluding, research and development needs are outlined.
