Abstract

The invention relates to an integrated traffic surveillance system having devices for measuring environmental and weather data, having traffic sensors, and a traffic surveillance control centre for storing and processing the detected data, and communication devices for carrying out the data exchange with the measuring devices and with the data users. The invention also relates to a driver assistance system which operates autonomously or is part of the integrated traffic surveillance system. It is proposed according to the invention that in order to reduce the environmental pollution the integrated traffic surveillance system and/or the driver assistance system take actions to control a traffic system. The control actions comprise the output of information, warnings and/or recommendations to road-users, interventions in the infrastructure and/or interventions in the vehicle.

The invention also relates to a digital map which is part of the integrated traffic surveillance system and/or the driver assistance system. It is proposed according to the invention that immission data are stored as attributes in the digital map.
