Filtering method for determining travel speeds and times and remaining domain speeds

摘要

An efficient calculation of travel times or travel speeds is made possible by a system or method for determining the average travel speed or travel time on at least one street or section of a road traffic network DOLLAR A by processing recorded measured traffic values (Fig. 1, v (x)) , regarding locations (x) on the street of the road network, with DOLLAR A - the traffic measured values (v (x)) being entered in a grid discretized along the street with regard to the location (x), DOLLAR A - for determining the weight profile ( g (x)) along the grid of the road for a measured traffic value for each location of the grid of the road a weight representing the meaning of this measured traffic value for the travel time and / or cruising speed at this location is defined, the weight of a traffic Define the measured value as the highest at the measuring location and as decreasing with increasing distance from the measuring location rt becomes, DOLLAR A - the course of traffic along the grid of the street by means of the existing traffic measured values at the locations of the grid for locations without existing traffic measured values by equating the traffic measured values with the next-adjacent existing traffic measured values and subsequent multiplication with the weight course is determined via the location, DOLLAR A - the average cruising speed or travel time for the road or a section of the road through the integral or the sum of the values of the traffic history along ...
