This paper presents the problem of scheduling security teams to patrol a mass rapid transit rail network of a large urban city. The main objective of patrol scheduling is to deploy security teams to stations of the network at varying time periods subject to rostering as well as security-related constraints. We present several mathematical programming models for different Variants of this proble...

Urban rail transit brings huge economic and social benefits to the society, however, the event of accidents and breakdown of subway can cause a wide range of traffic impact, significant personal and economic losses and even cause traffic paralysis. Current domestic emergency dispatch and command model is basically "man-based", therefore the validity and effectiveness of emergency scheduling dec...

In order to realize voltage stabilization and energy saving of rail transit traction supply system, a Li-ion battery energy storage system (BESS) is presented for application in the DC traction grid to reuse the braking energy of the vehicles. According to the models of traction substation, power lines and vehicles, the braking energy saved by BESS is calculated in MatLAB/Simulink, and the perf...

BRT appears to be less expensive to build and operate than tram systems but can it really approach the performance level of a tram system and what is the environmental performance of comparable systems? This paper reports systematic research on these issues, particularly relating to where an urban transit system seeks to attract discretionary car users. A model has been developed to compare the...

A 30.5km railway will soon be completed that links the Northwestern part of the territory with the metro area of Hong Kong. This HK$46 billion investment in the West Rail projects will form a major railway strategic and territorial development for the coming 20 years of Hong Kong. There are nine stations provided within the alignment of the West Rail, 6 of which are located in the northwestern ...

lated this reduced highway need as 4.45 lane-miles (7), and crediting this saving to BART, the freeway-to-rail efficiency ratio changes from 25.2 to 25.1. Construction-energy is not the entire story, however. One must also consider operating-energy. The operating-energies of BART, buses, and cars are 4740, 2900, and 8310 Btu/PM, respectively, including both propulsion energy and a pro rata shar...

Public transit plays a key role in shaping the transportation structure of large and fast growing cities. To cope with high population and employment density, such cities usually resort to multi-modal transit services, such as rail, BRT and bus. These modes are strategically connected to form an effective transit network. Among the transit modes, bus stops need to be properly deployed to mainta...
