Embodiment 2

[0109] The core idea of ​​embodiment 2 is the same as that of embodiment 1, and the difference is that embodiment 2 is more perfect, and may further include: a filtering module, which is used to filter source data with wrong time and / or GPS coordinates in the source data; The coordinate conversion module is used to convert the GPS coordinates in the source data into electronic map coordinates.

[0110] In the floating vehicle source data, some parameters of the source data may obviously not meet the requirements, and they should be removed as soon as possible through preset conditions to avoid increasing the burden of subsequent data processing and reducing the accuracy of the result information. For example, if the time parameter of the source data is obviously not within the current processing cycle, or the GPS coordinates are obviously not within the processing area of ​​the system, then it is certain that the source data is wrong and needs to be filtered out.

Embodiment 3

[0116] The core idea of ​​embodiment 3 is the same as that of embodiments 1 and 2, so the similarities will not be described in detail. The difference is that the embodiment 3 can also integrate and process the road condition information source data collected by other collection methods.

[0117] Traditional traffic information collection methods generally use fixed detection methods to collect data, such as induction coils, detectors, video surveillance, etc., all of which belong to the fixed detection type, mainly measuring the changes of real-time traffic flow at fixed points. The floating vehicle mobile acquisition technology has obvious disadvantages, such as limited measurement range, limited measurable parameters, high installation and maintenance costs, and is greatly affected by environmental and weather factors. The floating car belongs to the mobile monitoring method. It measures the characteristics of dynamic changes in traffic flow at discrete points in the traffic...

Abstract

A method for collecting and issuing real time dynamic traffic information includes receiving source data collected by floating vehicle, carrying out treatment periodically on source data from various floating vehicles, obtaining road state information of each road section traveled by each floating vehicle through calculation, integrating and treating road state information of multiple traveled road section to calculate out road information of each unit element in traffic path then issuing relevant traffic information data according to requirement.

Description

technical field [0001] The invention belongs to the field of processing and application of urban road traffic condition information, and in particular relates to a method and system for collecting, processing and releasing real-time dynamic traffic information. Background technique [0002] In recent years, urban traffic congestion, frequent traffic accidents, deterioration of the traffic environment, and energy shortages have become common problems faced by all countries in the world. Both developed and developing countries are suffering from traffic problems. The traditional way to solve traffic problems is to build or expand roads. However, with the growth of population, the per capita living area in cities is decreasing day by day, and the space available for building roads is also getting less and less. At the same time, the traffic system is a complex and comprehensive system, and it will be difficult to solve traffic problems if considered from the perspective of road...
