1. A cellular phone, comprising:
- memory configured to store map data, the map data including known roads and walking paths;
a global positioning system (GPS) module configured to i) transmit vector and location data and ii) receive traffic reports from a remote traffic monitoring system; and
an adaptive map building module including;
a path determining module configured to i) determine a travel path of the cellular phone based on the vector and location data ii) and determine a speed of the cellular phone on the travel path;
a comparing module configured to i) compare the travel path to the known roads and walking paths and ii) compare the speed to first and second predetermined speeds; and
an identifying module configured to, i) in response to the comparison of the travel path to the known roads and known walking paths and to the comparison of the speed to the first and second predetermined speeds, selectively identify new walking paths and, ii) in response to the determination, selectively add the new walking paths to the map data.

Abstract
A vehicle comprises memory for storing map data and a global positioning system (GPS) module that transmits vector and location data and that receives traffic reports from a remote traffic monitoring system. An adaptive map building module includes a path determining module that determines a travel path of the vehicle based on the vector and location data, a comparing module that compares the travel path to roads defined by the map data, and an identifying module that selectively identifies new roads based on the comparison.

10. A cellular phone, comprising:
-
memory configured to store map data, the map data including known roads; a global positioning system (GPS) module configured to i) transmit vector and location data and ii) receive traffic reports from a remote traffic monitoring system; and an adaptive map building module including; a path determining module configured to determine a travel path of the cellular phone based on the vector and location data; a comparing module configured to compare the travel path to the known roads; and an identifying module configured to, i) in response to the comparison of the travel path to the known roads, determine whether new roads have been created, and ii) in response to the determination, selectively add the new roads to the map data, wherein the GPS module is configured to, in response to the determination, increase a transmission rate of the vector and location data.
