Opis:: Air quality problems in cities are often a cause for worry. The air quality index is increasing daily, leading to an increase in cancer and many respiratory problems. Road transport in an urban area is a significant cause of air pollution. The vehicles must meet Indian emission regulations for which the emissions are measured using legally mandated standard driving cycles that did not accurately reflect real-world driving emissions because of varying traffic conditions, meteorological conditions, driving behaviour, vehicle power, performance, etc. This study focuses on real-time emissions of gaseous pollutants hydrocarbon (HC), carbon dioxide (CO2), carbon monoxide (CO), and nitric oxide (NO) from vehicle exhaust pipes under heterogeneous traffic conditions. The emissions were measured using a Portable Emission Measurement System (PEMS). The PEMS used was an AVL MDS 450 analyser mounted on the vehicle, and onroad emissions were captured. The test sample consists of four passenger vehicles with varying engine sizes, manufacturers, and fuel. The test route comprises city and highway areas, and it was discovered that the emissions were reduced by 40 to 70% on highways compared to the city. In petrol BSIV and BSVI engines, the emission was reduced to 41.73% for CO, 46.90% for HC, and 64% for NO in the city area. Speed and emissions scatter graphs were plotted for the vehicles, and it was found that in the city area, the optimum speed for less emission is between 30-40 km/h, and on highways, the optimum speed is 80-90 km/h. The emissions were also sensitive to the rate and frequency of acceleration and decelerations. This type of study is very limited in India, and more such studies are required for the assessment of air quality in metropolitan areas and successful traffic management strategies, as well as for determining instantaneous projections of pollutant emissions.

Opis:: In recent years, the UBAC has seen severe traffic congestion, resulting in various environmental and traffic problems at the university and its environs. This congestion was due to the significant expansions in buildings andan increase in the number of colleges in addition to the extensive use of private transport modes by students and university employees. This research was an attempt to find a solution for transportation problems in the UBAC, through studying the current transportation system inside the campus, and then suggesting alternatives to enhance the situation in the Campus and its environs as well. The study solutions focused on replacing the current diesel buses with battery-electric buses and restricting some of the private cars toward the Campus. This study supposes this transformation will reduce the CO2 emissions by (54%) in the morning peak hours and by (64%) in the afternoon peak hours, enhance the Passenger Car Unit (PCU) by (31%) in the morning peak hours and by (41%) in the afternoon peak hours, and will improve parking capacity by 114% inside the campus.
