Embodiment 1

[0086] Such as figure 1 As shown, Embodiment 1 of the present invention provides the reliability calculation method of urban rail transit line operation service, and described method comprises the following steps:

[0087] Step 1: Calculate the number n of delayed trains in the delayed state by simulation D and the delay time of each delayed train j Suppose there are m stations and n trains in the line operation;

[0088] Step 2: According to the calculation formula of train punctuality reliability: (where λ * is the delay effect coefficient), calculate the train punctuality reliability; according to the number n of delayed trains obtained in step 1 D and the delay time of the delayed train at each station According to the delay time of trains running on line L in T time period Group the trains according to the delay time, and divide them into p groups, x k Represents the number of components owned by the kth group of all running trains on the line on the horizontal...

Embodiment 2

[0157] Embodiment 2 of the present invention takes the Beijing rail transit system as an example, and provides a method for calculating the reliability of urban rail transit line operation service under the state of delay, including the following steps:

[0158] Step 1: Based on the existing data of the inbound and outbound traffic of the Batong Line of Beijing Metro, the passenger OD data of the field survey, the inbound and outbound volume of each station, and the inbound rate, conduct a simulation study on the delay of the line.

[0159] (1) Assumptions:

[0160] 1) Taking Beijing Subway Batong Line as the simulation background, the simulation time T=7200s T is two hours during the peak time of 7:00-9:00. And it is assumed that the distance between the stations of the Batong Metro Line is 2000m. The influence of station distance length factor on line operation service reliability is not considered.

[0161] 2) During the simulation time period of T=7200s, on the subway Ba...

Abstract

The invention provides an urban rail transit line operation service ratability calculation method, and relates to the technical field of urban rail train operation control. The method includes the steps that according to train operation simulation and a train working diagram, the number of delayed trains and the delay time of the delayed trains are determined so as to calculate the train punctuality reliability; meanwhile, according to the delay time, a line operation transportation capacity coordination degree solving model is determined to calculate the line operation transportation capacitycoordination degree and the density of standing passengers in the train; finally, according to a gain-type weighted fusion model in combination with the punctuality reliability, the line operation transportation capacity coordination degree and the density of standing passengers, an operation service reliability model is constructed to calculate the operation service reliability. By utilizing thegain-type weighted fusion method, the line operation service reliability model based on a 'reward and penalty' function is established, and by considering the influence of various operation parameterweights, comprehensive evaluation of the urban rail transit line operation service ratability is realized.

Description

technical field [0001] The invention relates to the technical field of urban rail train operation control, in particular to a method for calculating the reliability of urban rail transit line operation service. Background technique [0002] In recent years, with the rapid development of my country's urbanization process, the scale of the city has continued to expand, the urban population has also increased, and the travel needs of residents have also increased. The resulting urban traffic service quality has gradually changed to It is urgent to solve the core issues that urban residents are concerned about. Urban rail transit, as the primary means of transportation for residents of extra-large or medium-sized cities, has the advantages of low land use, large transport capacity, comfort and convenience, punctuality and reliability, and green safety. It has become one of the transportation modes for rapid urban development. [0003] With the rapid development of urban rail tra...
