Freeways were originally conceived to provide virtually unlimited mobility to road users. However, the continuous increase in car ownership and demand has led to a steady increase (in space and time) of recurrent and nonrecurrent freeway congestion, particularly within and around metropolitan areas. Freeway congestion causes excessive delays, increases fuel consumption and environmental polluti...

Wireless sensor networks (WSNs) are attracting increasing research attention, due to their wide spectrum of applications, including military purposes for monitoring, tracking and surveillance of borders, intelligent transportation systems for monitoring traffic density and road conditions, and environmental applications to monitor, for example, atmospheric pollution, water quality, agriculture,...

Objective To investigate the relation between exposure to both air and noise pollution from road traffic and birth weight outcomes.Design Retrospective population based cohort study.Setting Greater London and surrounding counties up to the M25 motorway (2317 km2), UK, from 2006 to 2010.Participants 540 365 singleton term live births.Main outcome measures Term low birth weight (LBW), small for g...

BACKGROUND Epidemiological studies suggest that long-term exposure to transport noise increases the risk for cardiovascular disorders. The effect of transport noise on blood pressure and hypertension is uncertain. METHODS In 1993-1997, 57,053 participants aged 50-64 year were enrolled in a population-based cohort study. At enrollment, systolic and diastolic blood pressure was measured. Incide...

One of the most critical issues in modern cities is transportation management. Issues that are encountered in this regard, such as traffic congestion, high accidents rates and air pollution etc., have pushed the use of Intelligent Transportation System (ITS) technologies in order to facilitate the traffic management. Seen in this perspective, this paper brings forward a road traffic management ...

The Blue Mountains of New South Wales, Australia is a populated area that includes a world heritage listed area. There is concern about the impact on the national parks of the pollution that may result from stormwater runoff from the roads in the area. A rainfall simulation experiment was undertaken on two areas with paved and unpaved road segments. Water quality parameters were examined, inclu...

Combustion of fossil fuels by the on-road vehicles is major contributor air pollution which affects surrounding vegetation and their habitat in addition to human health hazards. Study on concurrence between vehicular greenhouse gas emissions associated plant community important assess present day problem scenario environmental equilibrium. An ecological analysis has been carried out from five l...

With the growing number of vehicles and users, monitoring road and traffic within cities is becoming a huge research challenge. With the urban scale enlargement coupled with the exponential growth in the number of vehicles, South Africa (SA) is not an exception. Consequently, congestion and pollution (i.e. noise and air) have become the order of the day. Road congestion and traffic-related poll...

According to the change of air quality in Beijing-Tianjin-Hebei region, this paper analyzes pollution characteristics environment constructs evaluation model, and finds that main sources affecting region are coal combustion automobile exhaust. By using flow-diffusion equation, concentration gradients Second Ring Road, Fourth Sixth Road Beijing given. Finally, also puts forward specific counterm...
