When providing travel guides for a specific route in a metro network, we often place the route around the center of the map and annotate stations on the route with thumbnail photographs. Nonetheless, existing methods do not offer an effective means of customizing the network layout in order to accommodate such large annotation labels while preserving its planar embedding. This paper presents a ...

Metro systems are one of the most important transportation systems in people’s lives. Due to the huge amount of energy it consumes every day, highly-efficient operation of a metro system will lead to significant energy savings. In this paper, a new integrated Energy-efficient Operation Methodology (EOM) for metro systems is proposed and validated. Compared with other energy saving methods, EOM ...

In this paper we investigate the effect of the Delhi Metro, an intra-city mass rail transit system, on air pollution within Delhi. To identify effects on pollution, we exploit the discontinuous jumps in metro ridership, each time the network is extended. Our identifying assumption is that in the absence of the extension there would be a smooth transition in pollution levels. We find strong evid...

infrastructure development being the major construction activity undertaken with the support of the government to eradicate poor transport infrastructure, to cater to ever-increasing population, to reduce the usage of own vehicle and environmental impact thereof, the concept of mass rapid transit system came into existence. among the various mass rapid transit system modes, metro rail construct...

Timetable design is crucial to the reliability of a metro service. In terms of the delays caused by passengers’ boarding and alighting behaviors during rush hours, the planned timetable for a metro line with high-frequency service tends to be difficult to implement. General oversaturation events, rather than accidents or track damage, still have a significant impact on metro systems, so that tr...

In this paper, we explore whether the geography of bank services has been converging toward the market since banking geographic deregulation. We use Illinois as a study area and examine changes in various market segments such as metro and non-metro markets, and regional markets. We adopt the Spatial Concentration Index (SCI) and the related supply and demand SCI deviations to measure changing s...
