The number of vehicles on the road increases daily, causing many fatal accidents and wasting much time for average commuter every day due to congestion. Vehicular ad hoc networks (VANETs) were introduced overcome these issues by enabling vehicle-to-vehicle communication vehicle-to-infrastructure communication. prime challenge in VANETs is necessity very low delays, especially safety-related app...

The water quality of rivers, lakes or reservoirs changes in both short and long term. For a given catchment with known pollution sources, different combinations of hydrologic and pollutants discharges scenarios may result in different impacts in the water quality. The objectives of the present work were to analyze the methodologies currently used for assessment of pollution impacts in lakes and...

Petrol powered traffic has replaced domestic heating and industry as the main causes for urban air pollution (Colvile, Hutchinson, Mindell, & Warren, 2001). Automobile combustion engines are responsible for the better part of a city’s CO2 and NOX pollutants. The amount of pollutants emitted by a vehicle largely depends on fuel consumption: the more fuel the vehicle consumes, the higher its emis...

Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infras...

One of the principal reasons for the construction of bypass roads in towns is the removal of through-traffic from the center of a town or city to the periphery, for the purpose of improving the flow of traffic, reducing travel times, and reducing road accidents. Bypass roads, however, have also environmental and economic consequences. On the one hand, they reduce noise and pollution emissions a...

the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...
