Description

A traffic condition monitoring method and system based on big data

technical field

The invention relates to the technical field of traffic condition monitoring methods, in particular to a traffic condition monitoring method and system based on big data.

Background technique

Under the prior art, with more and more urban vehicles, roads become more and more congested, and traffic jams become more and more serious, seriously affecting people's daily life.

Compared with traditional data warehouse applications, big data analysis has the characteristics of large data volume and complex query and analysis. The four "Vs" of big data, or characteristics, have four levels: First, the volume of data is huge. From the TB level, it has jumped to the PB level; second, there are many types of data. The aforementioned web logs, videos, pictures, geographic location information, etc. Third, the processing speed is fast, and the 1-second rule can quickly obtain high-value information from various types of data, which is also fundamentally different from traditional data mining techniques. Fourth, as long as the data is used rationally and analyzed correctly and accurately, it will bring high value returns. The industry summarizes it into four "Vs" - Volume (large data volume), Variety (variety of data types), Velocity (fast processing speed), and Value (low value density).

The application of big data analysis in the field of traffic condition monitoring technology has also attracted more and more attention.

Contents of the invention

In order to solve the problem that traffic conditions cannot be quickly transmitted to drivers in the prior art, the present invention provides a traffic condition monitoring method and system based on big data, which utilizes the location information uploaded by vehicles to share information about traffic accidents or road construction. Information, and can remind the current road conditions in real time, which can be of great help in reducing road congestion and relieving traffic pressure.

The technical scheme adopted in the present invention is as follows:

A traffic condition monitoring method based on big data, comprising the following steps:

A. The in-vehicle navigation and positioning system uploads vehicle data to the cloud server when encountering road congestion;

B. The cloud server marks and stores the vehicle data processing to form road condition information;

C. Ordinary vehicles confirm the driving destination and upload it to the cloud server;

D. The cloud server analyzes the driving route through the destination, and compares the driving route with the road condition information. If there is road congestion on the driving route, it will prompt the ordinary vehicle and recommend a new one. route.

The vehicle data includes data on the cause of congestion where the congestion occurred, vehicle position data, and vehicle condition data.

In step A, the in-vehicle navigation and positioning system uploads the vehicle data at regular intervals.

In step C, ordinary vehicles upload destinations in real time.

A traffic condition monitoring system based on big data, including a navigation and positioning system and a cloud server in the vehicle, the navigation and positioning system is used to collect vehicle data when the vehicle encounters road congestion and uploads to the cloud server, and the cloud server is used to receive The driving destination of the ordinary vehicle and formulate the driving route, and compare the driving route with the vehicle data.

The beneficial effects brought by the technical scheme provided by the invention are:

In the big data-based traffic condition monitoring method and system of the present invention, the vehicle at the location of the accident uploads the vehicle data to the cloud server, and the cloud server processes the marking and stores it. The driving position data of ordinary vehicles is also uploaded to the cloud in real time. The cloud server judges and reminds.

The present invention makes full use of the advanced nature of big data and cloud computing to bring people the most convenient traffic service. First of all, if there is construction on the road or a traffic accident occurs, the in-car navigation and positioning system will transmit the location of the accident to the cloud, and the cloud will store the location information to the server. Whenever a vehicle is about to drive towards an accident or construction road, the cloud will send an alert to it, predicting that the road is under construction or a traffic accident has occurred, thus avoiding traffic jams caused by accidents.

Because the cloud server keeps the current location information of all vehicles, the present invention also has a great help for vehicle loss and querying the vehicles involved in accidents.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Embodiment one

As shown in accompanying drawing 1, a kind of traffic condition monitoring method based on big data comprises the following steps:

A. The in-vehicle navigation and positioning system uploads the vehicle data to the cloud server when encountering road congestion; the vehicle data includes the congestion cause data, vehicle location data and vehicle status data.

In this embodiment, the in-vehicle navigation and positioning system uploads the vehicle data every ten minutes.

B. The cloud server marks and stores the vehicle data processing to form road condition information;

C. Ordinary vehicles confirm the driving destination and upload it to the cloud server;

In this embodiment, an ordinary vehicle uploads the destination to the cloud server in real time.

D. The cloud server analyzes the driving route through the destination, and compares the driving route with the road condition information. If there is road congestion on the driving route, it will prompt the ordinary vehicle and recommend a new one. route.

Embodiment two

A traffic condition monitoring system based on big data, including a navigation and positioning system and a cloud server in the vehicle, the navigation and positioning system is used to collect vehicle data when the vehicle encounters road congestion and uploads to the cloud server, and the cloud server is used to receive The driving destination of the ordinary vehicle and formulate the driving route, and compare the driving route with the vehicle data.
