Portable road-side laser traffic survey device and survey method thereof

Abstract

The invention discloses a portable road-side laser traffic survey device which comprises a road-side laser traffic survey instrument and a bracket arranged at the bottom of the road-side laser traffic survey instrument, wherein a laser sensor is arranged in the road-side laser traffic survey instrument and electrically connected with a built-in wireless routing module; the wireless routing module is electrically connected with a WIFI module and a main control circuit; and the main control circuit is electrically connected with an electric quantity display module and a GSM (Global System for Mobile Communications) network module. The device disclosed by the invention realizes high detection precision and complete detection data; the detectable data includes traffic flow, vehicle model, wheel base, time headway, space headway, time interval, certainty factor and the like; the device has the advantages of portability, small volume, light weight, convenience in carrying, stable and reliable work, energy saving and environmental protection, no external wiring and no pavement damage, and being free of installation; and by adopting mobile Internet technology, data transmission is performed through a 2G / 3G / 4G mobile network, and fast and comprehensive release of traffic information is realized.

Description

technical field [0001] The invention relates to the technical field of traffic behavior research, in particular to a portable roadside laser traffic survey device and a survey method thereof. Background technique [0002] Traffic behavior research is an important research direction in the field of intelligent transportation. It is of great practical significance to collect real traffic data, analyze related traffic behavior, optimize and improve the existing traffic system, etc. In the actual process, traffic data collection often requires a lot of cost and manual intervention, and the sampling rate and accuracy are very limited. The lack of sufficient real and detailed traffic data support has brought great difficulties to the in-depth study of the nature of large-scale and long-term traffic behavior. difficulty. [0003] At present, the most widely used vehicle detection technology is the ground induction coil, but it will cause great damage to the road surface and cannot...

Problems solved by technology

In the actual process, traffic data collection often requires a lot of cost and manual intervention, and the sampling rate and accuracy are very limited. The lack of sufficient real and detailed traffic data support has brought great difficulties to the in-depth study of the nature of large-scale and long-term traffic behavior. difficulty

[0003] At present, the most widely used vehicle detection technology is the ground induction coil, but it will cause great damage to the road surface and cannot be used in wireless and mobile applications.

However, there are some commonly used vehicle detectors such as geomagnetic, microwave, infrared, ultrasonic, video, etc., and their comprehensive effects in wireless, low power consumption, and environmental protection applications are not ideal.
