The invention provides a road condition detection system based on vehicle GPS data, and the road condition detection system makes the best of the big data thinking and has the advantages of low cost, easy promotion, stability, reliability and the like. The road condition detection system based on the vehicle GPS data comprises a timer, a GPS data acquisition module, a map matching module, a vehicle unit speed calculation module and a comprehensive statistic module. GPS coordinates of different floating vehicles driving in a road network and marked time stamps are acquired in real time, the GPS coordinates are matched with coordinates in a preset road section in a map, then time and distance differences of the vehicles driving on the road section are calculated based on the GPS coordinates of the floating vehicles and the marked time stamps, thus the average driving speed of the floating vehicles on an original matching road section can be obtained, and statistics are conducted on the average driving speed of all the floating vehicles on the road section. In this way, the road condition of the road section is determined.
