Problems solved by technology

[0003] At present, bus positioning is mainly used for vehicle monitoring and alarming purposes, and has not formed an effective processing method for related dynamic information (geographical coordinates, speed, time). Unable to obtain, that is, the original dynamic information obtained has not yet been used as data support for dynamic bus scheduling decisions
[0004] At present, most of the dynamic dispatching of public transport adopts the dynamic dispatching method based on the event response mechanism, that is, the dispatching is carried out after the abnormal situation is discovered, and there is a certain lag

Embodiment Construction

[0107] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0108] figure 1 It is the application flow chart of the method of predicting the arrival time of vehicles; according to the real-time information, determine the actual travel time of shift k between station i and i-1, the current time period and the historical average travel time of the current road segment are known, and use Kalman filter The model predicts the arrival time of shift k+1 at station i. The premise is that shift k+1 arrives at station i later than shift k. If shift k+1 exceeds shift k halfway, shift k is predicted according to the order of arrival. According to the predicted arrival time of shift k+1, the predicted value of delay time of shift k+1 can be calculated and train train prediction can be performed.

[0109] figure 2 It is the flow chart of calculating the travel time delay of the bus section. First, according to the real-time in...

Abstract

The invention relates to a real-time information processing method in bus dynamic dispatching, which is specially used for dynamic dispatching of bus single or area multi-line of the ground. The real-time information comprises vehicle positioning information and passenger flow information; acquiring equipment comprises a GPS vehicle-mounted terminal and an IC card POS machine terminal; a processing method comprises the following steps: acquiring and transmitting real-time information; processing and preprocessing real-time information; carrying out secondary processing to the acquired data; taking relevant technologies of ITS and the computer of the bus vehicle positioning technology, the bus passenger flow acquisition technology, the network communication technology, WebGIS and the like as support, acquiring real-time information of ground bus line operation, carrying out processing on the real-time information, calculating operating state of vehicle delay time, section passenger flow, load factor and the like, and carrying out vehicle bunching recognition; and using a Kalman filtering model to predict the arrival time and delay time of the bus vehicle, and providing decision basis for dynamic dispatching measures.

Description

technical field [0001] The invention belongs to the field of bus dynamic information processing, and is specially used for the dynamic scheduling of ground bus single-line or regional multi-line. Background technique [0002] Bus dynamic dispatching is an important development direction of my country's ground bus operation organization in the future. At present, corresponding demonstration construction projects have been carried out in many cities in my country, and certain results have been achieved. With the development of ITS technology, the collection and transmission technology of dynamic information has become very mature, and it is widely used at home and abroad. However, under the premise of ensuring real-time performance, how to process dynamic information into a basis that can support bus dispatching decisions , further research is needed. Currently there are mainly the following problems: [0003] At present, bus positioning is mainly used for vehicle monitoring...
