Signal Coordination of consecutive intersections were carried out by thumb rule by coupling the indices depend on ratio of traffic volume to distance as well as modelled flow. As eminent resolution data is easily available from intersections, it becomes desire to analyses the actual stream of vehicle flow better to characterize is signal coordination desirable? As increase in vehicular populati...

Asthma is a common disease and appears to be increasing in prevalence. There is evidence linking air pollution, including that from road-traffic, with asthma. Road traffic is also on the increase. Routine surveillance of the impact of road-traffic pollution on asthma, and other diseases, would be useful in informing local and national government policy in terms of managing the environmental hea...

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...

Air pollution is associated with increased cardiovascular and pulmonary morbidity and mortality. The mechanisms of air pollution-induced health effects involve oxidative stress and inflammation. As a matter of fact, particulate matter (PM), especially fine (PM(2.5), PM < 2.5 μm) and ultrafine (PM(0.1), PM < 0.1 μm) particles, ozone, nitrogen oxides, and transition metals, are potent oxidants or...

In spite of epidemiological evidence concerning vehicular air pollution and adverse respiratory/cardiovascular health, many athletic fields and school playgrounds are adjacent to high traffic roadways and could present long-term health risks for exercising children and young adults. Particulate matter (PM(1),0.02-1.0 microm diameter) number counts were taken serially at four elementary school a...
