Abstract

A portable communication device for providing road conditions and monitoring traffic congestion for a user contains a device for sensing orientation of the portable communication device, including acceleration and/or deceleration of a vehicle in which the communication device is located, a memory, and a processor. The processor is configured by the memory to perform the step of calculating space time series data to determine traffic congestion characteristics, wherein the step of calculating space time series data includes at least one step selected from the group consisting of determining position of the portable communication device as a function of time, determining velocity of the portable communication device as a function of time, and determining acceleration of the portable communication device as a function of time.
