Intelligent transportation system (ITS) has gradually become reality with the increasingly wide application of GPS in car navigation system. It is wider and wider applied into traffic management to support short-tern traffic prediction, provide the information for public travel rapidly and effectively and realizes the effective supervision on traffic state. It can also relieve the pressure of highway road in our country. This paper focused on the study of floating car data technology based on GPS in ITS and developed relative procedure based on algorithm theory. It designed out a solution suitable for highway real time road condition system based on GPS floating car data technology after the demand analysis, functional decomposition and concept design on highway real time road condition system and best road and shortest time selection on driving by mathematical modelling so that achieve highway road optimization.
