Abstract
A method for collecting the information from the mobile devices for producing real-time traffic data is provided. The process ensures that the collection of data from a mobile device to be non-intrusive to the user of the mobile device by using only communication channels that are already open and by using only Global Positioning System (GPS) data from an application that is already running on the mobile device. The mobile device will participate in the data collection only if its battery power is above certain threshold level or if its battery is currently being charged. The method will not let a mobile device participate in the data collection process if the mobile device has already provided more than a threshold amount of data to the traffic data collection during a particular period of time. The method let only mobile devices that are moving beyond certain speed to participate.
