Embodiment Construction

[0018] Such as figure 2 As shown, the present invention obtains the method for road traffic flow nephogram in real time and comprises the following steps:

[0019] (1) see figure 1 , collecting the driving information of each motor vehicle in real time through the navigator installed on each motor vehicle 2 running on the road in the target area to support wireless communication, the driving information includes the current position information and the current speed information of each motor vehicle, Wherein, the current location information is the longitude and latitude information of GPS1 obtained by the navigator installed on the motor vehicle.

[0020] (2) Each motor vehicle 2 utilizes the navigator with wireless communication capability installed in it to transmit the current driving information of each motor vehicle collected to the data by any one of wireless transmission networks 3 such as WiMax, WiFi, GPRS, etc. Service Center.

[0021] (3) The data service center...

Abstract

The invention discloses a method for obtaining a road traffic flow cloud picture in a real-time manner, which comprises the following steps: (1) collecting driving information of all motor vehicles in the real-time manner through navigation instruments which can support wireless communication and are mounted on all the motor vehicles driving on a road in a target area; (2) transmitting the driving information collected through a wireless transmission network of all the motor vehicles to a data service data; (3) leading the data service center to store the received driving information of all the motor vehicles, and matching the driving information of all the motor vehicles with an electronic map of the target area for forming data of the road traffic flow cloud picture and transmitting to a user terminal; and (4) leading the user terminal to display the received data of the cloud picture on the electronic map of the target area in the cloud picture way. The method can realize the real-time display of road traffic flow, collect the road traffic flow information in the real-time manner by taking the ordinary vehicles as floating cars and improve the accuracy of the road traffic flow information.

Description

technical field [0001] The present invention relates to a method for acquiring road traffic flow cloud images in real time, in particular to real-time collection of road traffic flow information, which is transmitted to a service center via a network, and matched with an electronic map of the target area to form a cloud image of road traffic flow Data, real-time display of traffic flow information on the user terminal. Background technique [0002] With the popularization of cars entering the family, the number of cars has increased rapidly, and the proportion of driving private cars has continued to increase. Driving to and from get off work, traveling on holidays, and going out on business have become part of people's lives. Reasonable selection of exit and detour routes to quickly reach the destination requires timely and accurate understanding of the traffic conditions of the travel route. Reasonably guide travel and give full play to the service functions of highways m...
