Movable traffic information investigating instrument

Abstract

The invention discloses a movable traffic information investigating instrument which adopts a solar panel to absorb and store natural daylight energy and charge for a storage battery, and the storage battery provides power for the investigating instrument. The investigating instrument can adopt local storage or wireless transmission for collected traffic data, and can be mounted on an upright rod at one side of a road without an over-road portal frame or a cantilever rod body. The invention can evade a manual traffic flow investigation mode, has the advantages of simple and convenient installation, no need of taking commercial power, long-time storage of data, flexible and convenient communication, high detection precision and little investment, and can effectively improve the level of traffic detection of roads. The application of the invention can provide a scientific traffic flow investigating measure for road building, road alteration and traffic management.

Description

technical field [0001] The present invention relates to the field of traffic information management, and more specifically, relates to a "mobile traffic information investigation instrument" (hereinafter referred to as "investigation instrument" for short). Background technique [0002] With the rapid development of our country's economy, the speed of road construction is also developing rapidly, the number of motor vehicles has increased sharply, and urban expansion, old city reconstruction, and road widening are going on day after day. When building new roads and rebuilding old roads, or when the traffic management department is conducting traffic signal phase configuration and traffic signal timing, it is necessary to investigate and analyze the traffic flow, flow velocity, occupancy rate and other data of the road carefully. Finally, it provides a scientific basis for new roads and old road reconstruction or for traffic management. [0003] At present, designers who do ...

AI Technical Summary

Problems solved by technology

Since the investigation of traffic flow is only a phased work, if the equipment system for detecting traffic flow data is used, it should be dismantled after use, and there is no meaning of existence

However, these equipment systems cannot be applied due to harsh installation conditions, inconvenient access to mains electricity, inconvenient data storage, difficult communication, low detection accuracy, and large investment.

Due to this limitation, many traffic information surveys that should have been conducted in China were not carried out, which created many blind spots for road construction, road reconstruction and traffic management.
