GIS-Based On-Road Vehicular Emission Inventory for Lucknow, India (original) (raw)

MAPPING OF SPATIAL VARIATIONS OF DIFFERENT VEHICULAR EMISSIONS IN URBAN ROADS – A CASE STUDY

This paper aims at a systematic estimation through GIS based on-road vehicular emission inventory for the vehicular emissions that disturb the ambient air quality standards. The selected geographic area of study is HYDERABAD – with 6,809,970 population (according to 2014 census) and with a vehicular population of around 3.4 million. For Hyderabad, a geographic information system (GIS)-based methodology for emission inventory of on-road vehicles has been developed. The pollutants include: Hydro Carbons (HC); Carbon dioxide (CO 2) and Carbon monoxide (CO). Traffic Volume count was done at nine road intersections of varying land-use patterns to assess traffic count. Suitable net emission factor for each vehicle category is selected. Using Vehicular Kilometer Travelled (VKT), emissions are estimated and pollutants are spatially distributed in GIS platform. The inventory information can be used for future planning to reduce emissions.

Development of GIS-aided Emission Inventory of Air Pollutants for an Urban Environment

Advanced Air Pollution, 2011

Understanding types of pollutants and their emission rates is essential for control of air pollution. The emission rates, along with the rates of various chemical reactions those take place in the atmosphere, the prevailing meteorological conditions and topographical factors determine the extent of pollutions experienced by various environmental components. An emission inventory is a quantitative detailed repository of air pollutants emitted (along with their sources) into the atmosphere from a given area for a specified time period (Behera et al., 2011). Present and future inventories are critical components of air quality planning and modeling. The ultimate goal of the pollution control planning process is to identify and achieve emission patterns that do not result in violations of ambient air quality standards. An emission inventory should be able to provide: (i) a consistent estimate of total emissions of different pollutants, (ii) the spatial and temporal distribution of pollutants, (iii) the time-specific evolution of emissions and their distributions, (iv) the identification and characterization of sources, (v) tracking progress towards attainment of National Ambient Air Quality Standards (NAAQS) and emission r e d u c t i o n p l a n s , (v i) s e r v e a s t h e b a s i s i n m o d e l i n g f o r p r e d i c t i o n o f p o l l u t a n t concentrations in ambient air, and (vii) compliance records with allowable emission rates established by facilities and regulatory agencies. The broad source categories of air pollution in an urban area include; (i) transport (motor vehicles and railways), (ii) commercial establishments, (iii) industrial, (iv) domestic cooking/heating, (v) fugitive dust and (vi) biomass burning. There could also be some unique or specific sources in a particular area. Procedures and reliability of emission inventory for regular point, area and line sources are well-established. However, identification and quantification of fugitive/non-point emission sources (emissions not released through stacks, vents, ducts or pipes) are quite challenging. For these sources, emission factors (EFs) (EF: a ratio that relates the emission of a pollutant to an activity level) are either not developed or, if developed, are associated with high amounts of uncertainty. The important non-point sources include: traffic related non-exhaust (NE) emissions (tire, road and brake wear, road dust), evaporative emissions, raw material handling, open crushing, and biomass and agricultural residue burning. The development of a better emission inventory poses a challenge to air quality engineers, as it requires systematic in situ surveys to collect activity data and proper management www.intechopen.com

IRJET- Vehicular Emission Estimates of Various Air Pollutants in Residential Region of Lucknow

IRJET, 2021

Air quality is an topic of social concern globally in the era of rising industrial and vehicular air pollution. The pollution do arise from different sources out of which vehicular emission is prime source of pollution of ambient air and there exists an urgent need to the extent of vehicular pollution, especially considering the growing population , Industrialization and Urbanization there has and is likely to continue to be a high increase in the stock of road vehicle traffic in the city. This paper presents the Vehicular Emission of various Air Pollutants in Residential Region of Lucknow. It was found that the average per hour emission of CO in air is was 1206.77 gm/hr , Average HC emission as 672.8 gm/hr , Average NOx emission as 403.08 gm/hr and average PM emission as 56.2 gm/km , as been estimated by using Emission Factors based on Bharat Stage (BS) IV norms as prescribed by CPCB. It was found that Bikes were the major source of Vehicular emissions accounting for 65% share in CO emission , 39% share in HC emission , 70% share in NOx emission and 52% share in PM emission. The probable strategies to curb down the vehicular emissions could be adaptation of AVOID, SHIFT and IMPORVE measures by the Nodal Agencies for Pollution Control in Lucknow along with Public Awareness and Involvement .

Emission profile of pollutants due to traffic in Lucknow City, India

The human behaviors over the last few decades have changed the global atmospheric condition. Industrial emissions, transportation, intensification of agricultural practices and urban development have directly elevated the levels of pollutant gases such as CO2, NO2, CO and Particulate Matter (PM), which are probably to have inconsiderate climatic implications. Study is based on emissions from 2-Wheelers, 3-Wheelers, 4-Wheelers, Light Commercial Vehicles (LCVs) and Heavy Vehicles (HVs) at Lucknow City, India for three consecutive months; February 1, 2014 to April 30, 2014. The concentration of SO2, PM, CO and NO2 of selected location was 0.21 µg/m 3 , 6.27 µg/m 3 , 74.28 µg/m 3 and 40.64 µg/m 3 at Hazaratganj Road where as for Kalidas road it was 0.11 µg/m 3 , 2.87 µg/m 3 , 35.78 µg/m 3 and 18.77 µg/m 3 , respectively. The concentrations of above pollutants were more at Hazaratganj Road as compare to Kalidas road. The emissions profile of SO2, PM, CO and NO2 were within national ambient air quality standard.

Assessment of the impacts of vehicular emissions on urban air quality and its management in Indian context: the case of Kolkata (Calcutta)

Environmental Science & Policy, 2004

Air quality crisis in cities is mainly due to vehicular emissions. Transportation systems are increasing everywhere and the improvements in technology are insufficient to counteract growth. This paper examines the effect of vehicular emission on urban air quality and human health, and focuses on the unique features of an Indian mega city regarding its air pollution. A fact-finding survey was conducted to evaluate the status of air pollution at traffic intersections and the problem arising out of vehicular emissions in the study area. All the key pollutants are in excess of permitted levels. The severe detrimental effects of this pollution are reviewed. The problems have reached threatening dimensions. Vulnerable analysis (VA) has been carried out to evaluate the air pollution stress at different locations within the study area. Options for controlling mobile sources emissions are discussed and a strategic motor vehicle control strategy has been proposed to mitigate the air pollution in the city. Replacement of old vehicles, reformulating diesel fuel, introduction of liquid petroleum gas (LPG) and compressed natural gas (CNG), massive improvements in infrastructure and radical traffic management measures are among the actions that will need to be brought together to achieve this objective.

Vehicular traffic as a method to evaluate air pollution in large cities

Air pollution is a major concern for public health. Among the studies conducted to evaluate the association between air pollution and a wide variety of outcomes, some have used motor vehicle traffic data as a method for exposure assessment. This paper intends to revise and discuss some of the methodological aspects of studies that used this method, especially in areas where vehicles are the main generating source of pollutants. We performed a literature search with keywords related to air pollution and vehicle traffic, and selected articles published between the years 2000 to 2009. We noted different approaches for assessing the exposure among the studies using vehicle traffic, with emphasis on the method named Distance Weighted Traffic Density, which considers the number of roads, the distance from the location of interest and traffic itself. Moreover, we highlight the importance of using techniques such as geographic information systems (GIS) to measure this exposure.
