The present invention includes systems and methods for detecting a speed limit violation based on the movement of a cell phone in a moving vehicle. The system and method determine whether a speeding violation has occurred based periodic cell phone location data, the time between a cell phone's presence at one location and the next, and the speed limit of the section of a section of road that the cell phone could be located on. Embodiments of systems and methods of the invention detect whether a moving vehicle may be part of a public transit system, in which case the corresponding cell phones are removed from consideration. The system and method also include generating a speeding ticket for a car determined to have violated a corresponding speed limit, keeping a record of a speeding violation, and sending a request to settle the ticket if it is not paid on time. Also included in the invention are embodiments of systems and methods that detect whether a cell phone moving in a car is in engaged in a call, and if so, generating a ticket for a driving-while-talking violation.
