Metro Train Operation Plan Analysis Based on Station Travel Time Reliability

Abstract

The train operation plan plays an essential role in metro systems and directly affects transportation organization efficiency and passenger service level. In metro systems, passengers have paid more attention to the travel time reliability (TTR), reflecting the reliability of metro operation management. This article proposes an analysis method of train operation plan based on TTR in the station dimension. First, an automated fare collection (AFC) data-driven framework is established to calculate the station travel time reliability (STTR) and analyze the train operation plan at different periods. The framework structure consists of four steps: AFC data preprocessing, STTR calculation and assignment, clustering algorithm design based on SOM neural network, and train operation plan analysis and optimization. Second, the proposed method is applied to the Beijing metro network as a case study. Several promising results are analyzed that allow the optimization of the existing train operation plan. Our research shows that STTR is a good supplement for the existing metro operation assignment studies, which can help analyze and optimize the train operation plan effectively. This study is also applicable to other metro networks with AFC systems.

Post-COVID-19 performance evaluation of urban metro transit system in Delhi and influence on access mode

“…The passengers’ “waiting time” and “walking time” at the nearest metro stations to evaluate LOS of the metro route was conducted by ( Li et al, 2020 ) and ( Li et al, 2021 ). Further, ( Qi et al, 2021 ) and ( Xu et al, 2021 ) studied station travel time reliability (STTR) and travel time reliability (TTRe) to evaluate LOS based on actual time and standard travel time components along with “Passengers flow”, “Train running interval” and “Station Location”. In view of the research outcomes of the previous studies, the LOS in the present research considering the temporal context i.e.…”

Train Service Plan Design under the Condition of Multimodal Rail Transit Systems Integration and Interconnection

“…Li et al [17] focuses on the train service design problem incorporating multiple service routes and multiple train compositions, the problem lies on determining the turn-back stations, train composition, and frequency of each service route operated on the line. Xu et al [18] calculated the travel time reliability based on the passenger flow to study train service plan. Luo et al [19] aimed at express and local trains for regional rail transit lines and established an integer programming model with the objective of minimizing the travel time of passengers.…”

“…To summarize, the research on the integration and interconnection of multimodal rail transit systems mainly focuses on the evolving scheme and planning ideas, and research methods are mainly based on qualitative analysis [3][4][5]. For the perspective of designing a train service plan, most of the researches focus on trunk railway system [9][10][11] or other single-modal urban rail transit system [14][15][16][17][18][19][20].…”
