Abstract

The present invention relates to a natural traffic flow-based expressway vehicle behavior acquisition device and method. The acquisition device comprises a shell and a main control module arranged in the shell; the shell is provided with a card groove for accommodating an expressway toll station charging card; and the main control module comprises a control unit as well as a vehicle behavior data acquisition unit, a first wireless communication unit and a power supply unit which are all connected with the control unit, wherein the vehicle behavior data acquisition unit acquires vehicle behavior data including real-time positions, velocities and tri-axial accelerated velocities of vehicles, the control unit stores the real-time positions, velocities, tri-axial accelerated velocities of the vehicles and corresponding acquisition time, the control unit transmits data to the outside or receives remote control commands through the first wireless communication unit, and the power supply unit provides a working power source for other units. Compared with the prior art, the natural traffic flow-based expressway vehicle behavior acquisition device and method of the invention can transform social vehicles into test vehicles intangibly and obtain comprehensive, real and objective vehicle behavior data.

Description

technical field [0001] The invention relates to the field of traffic information collection, in particular to a device and method for collecting behavior of expressway vehicles based on natural traffic flow. Background technique [0002] Natural driving research refers to the research of using a high-precision data acquisition system to observe and record the driver's real driving process in a natural state (that is, without interference, without the presence of experimenters, and in daily driving conditions). Because natural driving can capture the driver's driving behavior and vehicle behavior most realistically, natural driving methods are widely used in traffic safety, automobiles and other fields. The traditional natural driving test needs to install a large number of sensors and other devices in the test vehicle, and the installation work is complicated, which determines that only a small number of test vehicles can be used for natural driving. Through these rich sens...
