Urbanization has paved the way for higher levels of comfort and standard of living. Rapid urbanization has thus caused an increase in the number of vehicles and this, on the other hand, is causing another set of problems including lack of space, reduction in natural resources, environmental pollution, etc
RSM gives a basic report regarding fuel consumption, emission and factors resulting air pollution. These studies are useful in transportation engineering and help in bringing changes in the development of a sustainable environment. Another type of environmental survey involves locating structures such as monitor wells, that aid in detecting, analyzing and monitoring groundwater pollution.
Fuel E conomy studies (Fuel sales/Fuel consumptions)
Fuel sales data is the monthly sales of petrol and diesel, at the fuel stations along the project corridor or on the road stretches. Traffic levels along a study stretch vary during different periods of time i.e., in different months/seasons. A seasonal correction factor is drawn from fuel sales data. Information on this aspect is necessary to estimate the AADT, the factors for passenger vehicles are based on petrol sales, that of goods vehicles (Trucks/LCV’s) and buses on diesel sales seasonal variations of Traffic Volume. This is best understood by studying monthly historical traffic volumes on the project corridor.
The substances causing air pollution are collectively known as air pollutants. They may be solid, liquid or gaseous in nature. Pollutants are classified as primary and secondary air pollutants. Primary pollutants are those which are emitted directly to the atmosphere, whereas, secondary pollutants are formed through chemical reactions and various combinations of the primary pollutants. RSM collects basic information regarding pollution causes & standards from the existing database
The pollution caused due to the emissions from vehicles is generally referred to as automobile pollution. The transportation sector is the major contributor to air pollution. Vehicular emissions are of particular concerns since these are ground level sources and hence have the maximum impact on the general population. The rapid increase in urban population has resulted in unplanned urban development, increase in consumption patterns and higher demands for transport and energy sources, which all lead to automobile pollution. The automobile pollution will be higher in congested urban areas. RSM gives basic data for the Automobile pollutions.
