Tolling highway network traffic information acquisition and induction system based on path identification system

Abstract

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.

Description

Technical field [0001] The invention relates to a toll road traffic information collection and guidance technology, in particular to a toll road network traffic information collection and guidance system based on a path recognition system. Background technique [0002] Real-time, efficient, fast, and accurate traffic information collection and processing is the basis to ensure the normal operation of toll roads, but different road users and managers have different information requirements and real-time requirements. While driving, road users need to know the traffic state and travel time ahead in real time; the toll management department needs to collect the wheel number, axle number, license plate number of the driving vehicle at the entrance and exit of the toll road, the type of passenger car, the axle load of the truck, and Information such as total weight, route traveled, distance traveled, and cheating can be realized to realize charging according to distance traveled, vehi...

Problems solved by technology

[0011] After searching, it was found that the content disclosed in the Chinese Patent No. 201410186194.9 entitled "Dual-source Multi-Frequency Reading and Writing System and Method for Highway Full-Function Path Identification and Toll Collection" shows that it uses 840-845MHz or 920-925MHz to realize ETC vehicles and MTC Vehicle path identification does not use the 5.8GHz frequency band specified by the national standard. The vehicle and the 5.8G path identification station cannot realize two-way communication, and cannot receive traffic information sent by the identification station. Without the Bluetooth function of the dual-frequency pass card, real-time traffic cannot be transmitted Information relayed to road users

The content disclosed in the Chinese Patent No. 200710055079.8 titled "Electronic Non-stop Toll Collection System with Path Identification Function" shows that although the communication between the OBU and the roadside identification unit uses the 5.8GHz frequency band, it does not involve the path identification of MTC vehicles , OBU does not have bluetooth function and cannot relay real-time traffic information to road users

The content disclosed in the Chinese Patent No. 201210143304.4 titled "An Ambiguity Route Recognition System with Traffic Information Statistics Function" shows that it only involves the identification of OBU routes and the collection of traffic information, but only includes a certain road section. The traffic flow information at a point in time, the speed information of a certain vehicle, or the time information of a certain vehicle passing through a certain road section, the collected information is incomplete, and it is only calculated based on the serial number and time stamp of the vehicle unit, which cannot provide accurate and effective information on the expressway. Various data information required

Moreover, the path recognition does not take into account the MTC vehicles, and the OBU does not have a Bluetooth function, so it cannot transfer real-time traffic information to road users

The Chinese Patent No. 201310145891.5 titled "A Method for Realizing Traffic Status Acquisition Based on ETC Equipment" shows that although information on road congestion, traffic flow, travel time and travel speed is obtained, only the information of ETC vehicles is collected. Information, there is no information collection and route identification content of MTC vehicles, and the traffic information processing is simply processed based on the static data of the vehicle, which does not have real-time dynamics. The OBU has no Bluetooth function and cannot transfer real-time traffic information to road users.
