Abstract

In embodiments of the present invention, data that is transmitted over a network that is utilized by cell phones within multiple automobiles may be used to calculate real-time traffic conditions, including but not limited to the time it will take to travel a certain distance using a given route. Real-time traffic conditions may be calculated by, for example, measuring real-time traffic density for a specific geographic region. Traffic conditions and traffic density may be calculated using parameters including, but not limited to, a time of day, a day of the week corresponding to the real-time calculation of the traffic condition measure, a weather condition corresponding to the real-time calculation of the traffic condition measure; or some other parameter relating to traffic conditions. This real-time traffic condition data may be manually accessed by a user from their cell phone or automatically provided to a user'"'"'s cell phone.
