Mass Rapid Transit

In this study, we developed a model re-sample Recurrent Neural Network (RRNN) to forecast passenger traffic on Mass Rapid Transit Systems (MRT). The Recurrent Neural Network was applied to build a model to perform passenger traffic prediction, where the forecast task was transformed into a classification task. However, in this process, the training dataset usually ended up being imbalanced. To address this dataset imbalance, our research proposes re-sample Recurrent Neural Network. A case study of the California Mass Rapid Transit System revealed that the model introduced in this work could timely and effectively predict passenger traffic of MRT. The measurements of passenger traffic themselves were also studied and showed that the new method provided a good understanding of the level of passenger traffic and was able to achieve prediction accuracy upwards of 90% higher than standard tests. The development of this model adds value to the methodology of traffic applications by employing these Recurrent Neural Networks.

Mass Rapid Transit

Rapid transit systems (RTSs) will increasingly play an important role in the daily commute. However, RTSs are complex systems and are susceptible to degradation over time, and recurring RTS service disruptions are inevitable. Therefore, resilience should be considered in the design of an RTS network, to provide commuters alternative paths that enable them to work around service disruptions. This paper proposes a commuter-centric resilience index for RTS networks that is based on the concept of an acceptable commute time. The proposed index was applied to the Singapore Mass Rapid Transit network, and the findings revealed that the introduction of each new rail line increased the resilience of the RTS network. Ring lines or orbital lines appeared to be most effective in improving network resilience. The resilience index can also be determined for individual stations to help planners identify gaps in the RTS network and to provide useful insight for land use and transport planning. The proposed index would be applicable to RTS networks in other cities or regions, but while information on an RTS network can be sourced from the public domain, computation of the index requires the corresponding commuter trip data.

Mass Rapid Transit

The operation of a mass rapid transit (MRT) should consider the balance between total system costs and service level. For a MRT system, the main service is to provide passengers with the cost-affordable mobility, under the regulation of MRT service indicators; the government sets the minimum standards to ensure a certain level of MTR services. Thereby, how to establish an optimal operating timetable is one of the important operational issues for a MRT system. In the past research concerning MRT operations, most researches focused on the issues of train delay, energy saving, route design or overall system operating regards, and placed less focus on the optimal timetable problem. In the Kaohsiung Mass Rapid Transit (KMRT) system, the total ridership has not reached a predicted level, but the service provided in terms of the Train Service Plan (TSP) is more than needed. Therefore, a time-dependent time table for the KMRT system is crucial to minimize total system cost while maintaining the certain level of train service. In this research, we aim to develop a time-dependent timetable model which is able to dynamically adjust train schedule depending on the passenger spatio-temporal distribution demands during daily operation. The developed model will be solved by minimizing both the operating cost and passenger waiting cost. Finally, numerical case study and sensitivity analysis will be conducted to demonstrate the feasibility and effectiveness of the developed models and solution algorithms.

Mass Rapid Transit

This paper presents a method for optimizing train-speed trajectory between two neighboring stations of a mass rapid transit system. This research uses the MAX-MIN ant system of the ant colony optimization algorithms to minimize energy consumption based on the framework of a moving-block signaling system of the mass rapid transit system. The alignment gradient is considered for energy saving. Several constrains, for example acceleration/deceleration and jerk of the train, as well as the average train speed, are also addressed according to the requirements of practical systems. In conclusion, this method will be used to design an operational system.
