Abstract

This paper describes the development of a control algorithm for use in a traffic control system in Stuttgart which is intended to prevent an NO2 limit of 200 micrograms/m3 being exceeded. This means restricting vehicle speeds in good time in critical situations from the normal 80km/h for private cars and 60km/h for trucks to 60km/h for both. The model requires a) traffic data, b) wind speed and inversion data and c) historic values for emission concentrations. Details are given of the data collecting stations used in Stuttgart and problems posed by the topography. The relationship between NO, O3 and NO2 concentrations and the relationship between NO2 concentrations on the current day and on the previous day are examined.
