Research and demonstration projects sponsored by the U.S. Department of Transportation explored low cost and higher reliability alternatives to Global Positioning System (GPS) based Automatic Vehicle Location (AVL) systems. As a result, the GeoGraphics Laboratory has developed and tested AVL software for low-cost mobile phones and web mapping which allows for the collection, transmission, storage and mass consumption of location data (web-based mapping). This has lead to research in the following areas: 1) Development of j2me software for military specification Sprint-Nextel? mobile phones to allow the collection of Location data at a refresh rate of 2-5 seconds; 2) Creation of protocols and software on a mobile phone and on a web server for the efficient and timely (within 2 seconds of collection) transmission of location data to a database using, TCP sockets, and lightweight-webservices; 3) Creation of database structures and software development using Google\'s AJAX mapping tools to display at a glance bus location, bus routes, bus stops and bus stop information, \"map within a map\" and super high definition photos of the Bus stop; 4) Development of a user interface to allow bus drivers to easily update which vehicle and route they are running, and when they are active.
