Problems solved by technology

[0006] To sum up, none of the existing transportation capacity assessment methods for rail transit lines can accurately locate the capacity-constrained bottleneck section of the entire line. They are all transportation capacity assessment methods under the traditional train operation command mode, and they cannot be very accurate. Well adapted to the moving block train operation control mode under the condition of CBTC system

Abstract

The invention discloses a verification and assessment method of rail transport network transport capacity, comprising the following steps: selecting a city rail transport network required to assess, and building a database according to the practical network situation, wherein the database comprises traffic intersection data and wiring data; verifying the transport capacity which takes the intersection scheme as the clue; according to a train run chart, a turn-back state and train configuration in the intersection scheme, configuring data required by the operation run control system and other data required by simulation; obtaining transport capacity TaCa_1 by simulation; verifying the transport capability which takes the wiring scheme as the clue; according to the wiring model and wiring data in the wiring scheme, configuring the data required by the train run control system and other data required by simulation; obtaining the transport capability TaCa_2 by simulation; and weighting the transport capability TaCa_1 and TaCa_2 to obtain the assessed value of the network transport capability. The invention verifies and assesses the network transport capability on the basis of the simulation of train run process. The experiment proves that the verification and assessment results have high precision.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a CBTC-based method for evaluating the transportation capacity of rail transit lines. Background technique [0002] In recent years, rail transit in major cities in my country has developed rapidly. The train operation control method is also upgraded to the CBTC system control by the traditional driver according to the ground signal display driving. The so-called CBTC system refers to the communication-based train operation control system (Communication Based Train Control). Existing subway lines are gradually reaching the limit of transportation capacity. How to evaluate the transportation capacity of the rail transit system is a complicated issue, because there are many factors that affect the transportation capacity of the rail transit system, such as different types of trains, and a wide variety of infrastructure And its layout, different signal system standards, diffe...
