Abstract Oversaturated conditions are often observed during peak‐hour periods, especially for commuting metro lines serving as a corridor connecting suburb and urban areas due to its unidirectional passenger flow pattern. System operators concerned about the amount of passengers accumulated inside station at platform when train service cannot meet travel demand. In this article, we tackle system congestion issue develop compound strategy integrating control bus‐bridging service, mitigate...

Due to the unsuitable train delay prediction methods currently used in Netherlands, a more accurate method is needed. In this work, based on data provided by 2018 RAS Problem Solving Competition: Train Delay Forecasting, data-driven model established predict 20 min later. By combining current with operating conditions, influencing factors that may influence propagation are extracted after analysing mechanisms and movement structure. These considered as input features for random forest...

Short‐term passenger flow prediction is one key prerequisite of decision making in daily operations. Subway operators concentrate on both the efficiency model and accuracy results. In this study, authors explore a deep learning‐based hybrid model, which integrates long–short‐term memory neural network (LSTM NN) stacked auto‐encoders (SAEs), for predicting short‐term flows each station subway simultaneously. SAEs are employed to extract data features, involves mapping high‐dimensionality...

Abstract Primary delays are the driving force behind delay propagation, and predicting number of affected trains (NAT) total time (TTAT) due to primary (PD) can provide reliable decision support for real‐time train dispatching. In this paper, based on real operation data from 2015 2016 at several stations along Wuhan–Guangzhou high‐speed railway, NAT TTAT influencing factors were determined after analyzing PD propagation mechanism. The eXtreme Gradient BOOSTing (XGBOOST) algorithm was used...

Korla fragrant pear (KFP) with special fragrance is a unique cultivar in Xinjiang, China. In order to explore the biosynthesis molecular mechanism of chlorogenic acid (CGA) KFP, samples at different development periods were collected for transcriptome analysis. High performance liquid chromatography analysis showed that CGA contents KFP 88, 118 and 163 days after full bloom (20.96 ± 1.84), (12.01 0.91) (7.16 0.41) mg/100 g, respectively, decreased fruit development. Pears from these typical...

To reduce the operating cost and running time of demand responsive transit between urban rural areas, a DBSCAN K-means (DK-means) clustering algorithm, which is based on density-based spatial applications with noise (DBSCAN) was proposed to cluster pre-processing station optimization for passenger reservation design new variable-route service system that can promote urban–rural integration. Firstly, after preprocessing through algorithm used divide fixed sites alternative sites. Then, bus...

There usually exist a few big customers at ports of near-sea container shipping routes who have preferences on the weekly ship arrival times due to their own production and sale schedules. Therefore, in practice, when designing schedules, carriers must consider such customers’ time preferences, regarded as soft-time windows, improve customer retention, thereby achieving sustainable development during depression industry. In this regard, study explores how balance tradeoff between total...

We examine environmental discourse in conference calls and the relation between this firm value. measure amount of as frequency count environmentally-related topics transcripts calls. argue that greater indicates firms’ prioritization issues. Evidence amounts are associated with lower share price higher cost capital, which we interpret reflecting relatively costs environmentally responsible operations excess firm-specific benefits. Additional analysis examining general environmental, social,...

This paper aims to optimize a desirable fare structure for the public transit service along bus-subway corridor with consideration of those factors related equity in trip, including travel distance and comfort level. The factor is represented by distance-based strategy, which an existing differential strategy. level one considered area-based strategy new defined this paper. Both are referred combined composed strategies. flat applied determine reference social welfare obtain general...

This paper proposes to address the problem of simultaneous optimization liner shipping route and ship schedule designs by incorporating port time windows. A mathematical programming model was developed minimize carrier’s total operating cost simultaneously optimizing call sequence, arrival per call, sailing speed leg under window constraints. In view its structure, nonlinear nonconvex is further transformed into a mixed-integer linear that can be efficiently solved extant solvers provide...
