Problems solved by technology

Secondly, since the floating car sends various data of its own car at a certain time interval, when the data processing capacity of the control center is fixed, the more the number of floating cars, the longer the interval for sending data from the floating car will be , the above-mentioned floating car data update time interval of the Beijing taxi dispatching system is about 60 seconds. Judgment and treatment effect
Finally, since most of the data sent by the floating car is normal driving data, it is useless for judging the degree of road congestion and handling emergencies only based on the speed of the car. It can be said that the data transmission and processing method of the floating car technology is exactly The root cause of its inability to be promoted on a large scale

Embodiment Construction

[0022] The practical application cases of the present invention will be described below with reference to the accompanying drawings.

[0023] Case 1: In principle, the road area division of this system is bounded by intersections, but for overly long road sections, an appropriate distance should be taken to divide it into several sections, as shown in Figures L0001 and L0002. The division of plot areas is based on their functional areas. For example, a residential area is counted as an area. For example, there is no road between Q0001, Q0002, and Q0003, but they are three different areas, and they are divided separately. Come out; as shown in the figure, there is a parking lot Q0008 in the plot area Q0007, which is divided separately and given an independent number to facilitate the use of the parking lot.

[0024] Case 2: Vehicles C07 and C08 near the intersection X0012 are waiting for a red light. Although their speed is zero, their vehicle terminal judges that they are near...

Abstract

The invention relates to an intelligent transportation system, in particular to a trigger event area coding intelligent transportation system, which is especially suitable for the intelligent transportation system adopting the floating vehicle technology. The trigger event area coding intelligent transportation system is characterized in that the floating vehicle technology is taken as the basis on the aspect of the information acquisition technology, each vehicle terminal automatically filters the driving information of the vehicle, only the information which is worthwhile to grasp the urban road conditions is sent to the control center, and the content of the sent information is simplified in a code manner. Since the invention greatly reduces the information processing load of the control center and the difficulty for judging the road conditions, the problem that the transmission and processing links of the floating vehicle technology in the traffic information are difficult for supporting the large-scale vehicles is solved.

Description

technical field [0001] The invention relates to an intelligent transportation system, in particular to an intelligent transportation system using floating vehicle technology. Background technique [0002] With the impact of the wave of the automobile industry and the intensification of urbanization, the demand for logistics and transportation industries has grown rapidly, and has become a basic element of modern society. At the same time, it brings traffic congestion, traffic accidents, air pollution and many other problems, which gradually become part of our daily life. In order to cope with these challenges, relevant government departments have introduced a series of policies to meet the traffic demand, and expand the supply and carrying capacity of traffic by building more roads. However, such physical methods cannot be implemented sustainably due to space and financial constraints. Therefore, in order to provide the public with a more secure, convenient and environment...
