Traffic-related pollutants have been reported to increase the morbidity of respiratory diseases. In order to apply management policies related to motor vehicles, studies of the floating population living in cities are important. The rate of metro rail transit system use by passengers residing in Seoul is about 54% of total public transportation use. Through the rate of metro use, the people-flo...

37 INTRODUCTION As drivers age, the skills necessary for safe driving, such as vision, reflexes, flexibility, hearing and reaction time, begin to deteriorate. To cope with these changes, many drivers choose to adjust their driving habits as a means of retaining their mobility. Adjusting driving habits is one part of the puzzle; improvements to the roadway environment can be another. Traffic eng...

This paper provides new evidence on the link between airline tra±c and employment in a metro area. The evidence con ̄rms the common view that good airline service is an important factor in urban economic development. Frequent service to a variety of destinations, re°ected in a high level of passenger enplanements, facilitates easy face-to-face contact with businesses in other cities, attracting ...

Metro Ethernet has recently attracted remarkable attention due to its simplicity and low cost. Although Ethernet is the dominant technology in the Local Area Network (LAN) which usually handles small number of nodes, when deploying in Metropolitan Area Networks (MANs), it faces certain challenges. One major challenge is its broadcasting based address resolution scheme. A broadcast-based address...

BACKGROUND Nearly 40 years of research provides an extensive body of evidence about human health, well-being, and improved function benefits associated with experiences of nearby nature in cities. OBJECTIVES We demonstrate the numerous opportunities for future research efforts that link metro nature, human health and well-being outcomes, and economic values. METHODS We reviewed the literatu...

0. Abstract Portland Metro presents its version of a regional economic model with embedded input-output coefficients as explanatory variables in the model's employment sector equations. The Metro model implements the integration strategy as described by Coomes et al (1991), Stover (1994), and Rey (1997). Coomes et al first described the I-SAMIS model technique for linking I-O and econometric mo...

Is there a causal connection between house prices and labor force participation of married women?

Plausible, informal arguments have been advanced to support causation in either direction: prices raising participation (negative income effects of higher house prices lead...

Rail transit is developing rapidly in major cities of China and has become a key component of urban transport. Nevertheless, the security and reliability in operation are significant issues that cannot be neglected. In this paper, the network and station vulnerabilities of the urban rail transit system were analyzed based on complex network and graph theories. A vulnerability evaluation model w...
