General investigation system of road traffic sign information

Abstract

The invention relates to a general investigation system of road traffic sign information. The general investigation system comprises a hand-held intelligent terminal and a data storage server. The hand-held intelligent terminal consists of an internet access device, a GPS device, a camera device, an image acquisition module, a user interface and logic control module, a pile number calculation module, a network communication module, an image display module and a map display module. The data storage server includes a communication module, a database operation module and a traffic sign information database. According to the invention, the system can be used flexibly; individual newly-added or updated and replaced traffic sign data can be collected conveniently, thereby providing effective supplements for batch collection of traffic sign information during the driving process. The collected individual traffic sign data can be stored locally or uploaded to the data storage server at the cloud end, thereby updating and completing traffic sign information data timely.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, in particular to a road traffic sign information general survey system. Background technique [0002] The adjustment of national road network planning puts forward an urgent need for the general survey and optimization of road signs. The planning and adjustment of the national highway network requires traffic signs and markings to be adapted to meet the needs of road operation and safety for different functions. The renaming and numbering of expressways must be coordinated with the adjustment of traffic signs, and the formulation and adjustment of normative standards must also be based on the general survey, evaluation and optimization of existing traffic signs. [0003] With the development of concepts and technologies such as the Internet of Things, Internet of Vehicles, and sensor networks, the level of intelligent transportation has been greatly improved. At the same time, higher re...

Problems solved by technology

At present, the census of traffic signs in most cities is mainly based on manual means. This method has disadvantages such as low survey efficiency, poor precision, troublesome data statistics and analysis, and heavy tasks in the field and in the office.

Another shortcoming is that the traffic sign information obtained from the survey only has stake number information, and there is no other location information that can be used for networking, so it is difficult to load on the entire line or the entire network, and it is also difficult to compare and analyze horizontally with other roads of the same level; and, for Centralized census cannot take into account newly added or changed individual traffic signs, and it is not economical
