The invention discloses a tolling highway network traffic information acquisition and induction system based on a path identification system. The tolling highway network traffic information acquisition and induction system comprises a tolling highway outlet, inlet tolling lane system, a networking tolling center system, a 5.8G path identification station, a 5.8G path identification station monitoring system, a MTC vehicle double-frequency passing card, an ETC vehicle OBU and noncash payment card, an on-board multimedia terminal, and a traffic information processing system. The tolling highway network traffic information acquisition and induction system is advantageous in that by adopting the 5.8G Hz path identification station, the double-frequency passing card provided with the Bluetooth module, the OBU, and the on-board multimedia terminal, the path identification and traffic information acquisition and the traffic information push can be realized; by adopting the combination between the cloud calculation and the 5.8G path identification station distributed calculation, the processing and the prediction of the information such as the traveling time, the traffic flow, the travel speed, the traffic state, and the vehicle position of the tolling highway segment can be realized, and therefore the accurate and reliable front traffic information can be provided for the highway user.
