Traffic measurements conducted over a number of years enabled to determine the basic mobility ratios of residents of the Polish cities. AMS Metrics takes into consideration such ratios as: average number of trips, average distance of a trip in kilometers, seasonality of the traffic volume. These ratios are not subject to rapid changes in comparison to traffic volume on specific street sections. The values of the ratios were generated in 2011 based on trends and changes in traffic over the previous ten years.
