System and method to calculate routes comprising the steps of obtaining polygons with attributes of air and noise pollution from hourly maps (pollution map), wherein each polygon corresponds to a class of air and noise pollution from a predefined number of classes of air and noise pollution; split each segment of the road network  in sub-segments by the intersection with those polygons (distance contamination model); determine the corrected distance of the sub-segments, by applying to the actual distance of each sub-segment noise (K) and air pollution (W) multipliers obtained through the known average value of the respective class of pollution (contaminated distances map); calculate the route, considering the sub-segments with the corrected distances, which minimizes the total corrected distance (navigation) to obtain the desired routes (healthy route, less noisy route, less air polluted route).
