Abstract
The present invention is directed to a method for determining vehicular speeds over various travel routes that includes the steps: (a) for a plurality of mobile communication devices, determining a respective first geographic location at a first time and a second geographic location at a second later time; (b) determining a respective velocity for each cellular communication device over the distance between the first and second geographic locations; and (c) based on the respective velocities, providing to a driver at least one of (I) a velocity over a selected travel route, (ii) a traffic volume over the selected travel route, and (iii) an estimated time of travel over the selected travel route.
