Abstract
The present invention provides a method for finding the location of a mobile device user, and using the location to customize the information and to determine the way of delivering such information to the user. The mobile device user may request the information either with an interactive series of one or more requests, or by pre-selecting the type of message to be delivered. The customized information is transmitted only to the mobile device from which the request is originated. It can also be displayed at a public display unit (such as an electronic billboard), sent to a public broadcaster, posted on the Internet, or sent to a fax machine or a modem. The present invention also provides a method for determining traffic density and speed information that can be continuously updated. The traffic information together with a variety of traffic services can be transmitted to mobile devices users, displayed at inanimate devices (such as electronic billboards), publicly boradcasted, or posted on the Internet.
