OD-CONNECTIVITY EVALUATION SYSTEM ON URBAN RAILWAY NETWORKS FOR DISASTER COUNTERMEASURE

Dynamic OD Matrix Estimation Exploiting Bluetooth Data in Urban Networks

Time-Dependent Origin-Destination (OD) matrices are a key input to Dynamic Traffic Models. Microscopic and Mesoscopic traffic simulators are relevant examples of such models, traditionally used to assist in the design and evaluation of Traffic Management and Information Systems (ATMS/ATIS). Dynamic traffic models can also be used to support real-time traffic management decisions. The typical ap...

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter

Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...

Architecture for Operation Management in Urban Railway System

It is conspicuously to announce that China has already become the country with the largest-scale market as well as the fastest growing urban rail transit in the world. This article, from the perspective of production and operation, has described the status quo of the informationization of rail transit enterprises and analyzed the demands for functions of operation information system of these en...

Intelligent System for Urban Emergency Management during Large-Scale Disaster

The frequency and intensity of natural disasters has significantly increased over the past decades and this trend is predicted to continue. Facing these possible and unexpected disasters, urban emergency management has become the especially important issue for the whole governments around the world. In this paper, we present a novel intelligent system for urban emergency management during the l...
