The roads are the dominant mode of transportation in India today. India has dubious distinction of nation with about 8-10% towards road death which is nearly one lakh every year. Pavement surface quality is a primefactor which enhances the serviceability of a road. Pavement surface quality is spoken in unevenness and assessed in terms of the automobile wheels movements and suspension arrangement along with the drivers' understanding of speed and acceleration. Though, notwithstanding the rapid high-tech advancement of high-speed roughness checking apparatus, it should not be ignored that highway pavements are constructed for the drivers, who have ever been keenly aware of the relative degrees of ease or distress felt in traveling. Mostly, travellers believe in three basic things from the pavement surface; even trip, sufficient resistance to slipping, and enough power to shift the traffic to the following section of the highway configuration. Hence their insight on road surface quality should also be considered. In this case study an attempt has been made to maintain the roads by monitoring the roughness of road surface whether they exist in good, average or poor condition at specific reach of Chandigarh city in India.

It is very common part of discussion that normal structures lag behind in terms of energy saving and its corresponding impacts on environment. This drives research to show implementation of common solutions and concepts that can be easily applied by majority of individuals to fulfill sustainable and self-sufficient goals to lead to a better habitat to live in. The aim of paper is to explore proper application of most common and most essential cost-effective design solutions to make structure following a step towards self-sufficient in itself. The paper has emphasized on quantitative and mathematical approach of study generating owns secondary data, from various research papers that are based upon similar background aspects. The value analyzed for solar panel tilt should range from 20o-30o for maximum efficiency, similarly distance between panels should be 1m-1.6m and horizontal shading device and vertical shading device should have at least depth of 450mm and 700mm respectively. The study is limited to a particular climate and region. i.e., Northeast region of India and focuses only upon most critical parameters. This paper will provide new directions for self-sufficiency in structures, which will further add values to the domain of architecture and civil engineering. Further, new areas of research can be application of new design alternatives for self-sufficiency, with respect to several other climatic conditions and regions. [ABSTRACT FROM AUTHOR]

An investigational study on the ambient air quality of Aligarh city at six different locations designated as; Sir Syed Nagar, Jamalpur, Dodhpur, Center Point, Numaish Ground, Chungi was performed. Six primary and important locations of Aligarh city were chosen to monitor the quantities of key pollutants like PM10 and PM2.5. The outside areas were susceptible to extraordinary RSPM levels because of prevalent town ambient air excellence of Aligarh city and also due to high road traffic circulation at Dodhpur, chauraha and centre point. The concentration of PM2.5 at Aligarh city atmosphere was observed from 3.5 µg/m³ to 15 µg/m³ and PM10 level of concentrations at all the designated locations varied from 75 - 250 µg/m³.
