The invention discloses a traffic congestion road segment prompting system comprising an information acquisition device and a mobile inquiring terminal. The input end of the information acquisition device is electrically connected with a video acquisition device, a vehicle speed sensor and a vehicle flow meter respectively. The output end of the information acquisition device is electrically connected with a processor, a GPS positioning analyzer, a displayer and a storage device respectively. According to the traffic congestion road segment prompting system, different pieces of information of the same road segment is collected via the video acquisition device, the vehicle speed sensor and the vehicle flow meter so that relatively accurate road condition information can be obtained after processing of the processor. The condition of the traffic road segment can be further positioned by the GPS positioning analyzer so that error report of the road condition information can be prevented. The information condition of each road condition can be stored by the storage device so that understanding of historical road condition information is facilitated, and thus the future road condition can be preprocessed.
