In these days the traffic is expanding quickly and the activity conditions on Indian roads are exceedingly heterogeneous in nature because of variety of vehicles with various static and dynamic qualities. Due to unrestricted movements all fast and slow moving vehicles without any separation, the roads will face severe congestion and lower speeds. The greater part of national and state highways in India are two lane undivided roadway. These two lane highways achieve its greatest limit soon and require consistent up gradation to do this we need to estimate capacity of selected roads. In this present paper, attempts have been made to collect traffic volume for whole 7 days at national highways such as NH-206& NH-209. Also tried to compute PCU values at selected stretches on highways by using those values attempts has been made to estimate capacity and to compare those values with the regression equation values. Finally from the present study we got ADT at different section on highways, calculated PCU values as per Chandra's method at various sections on highways and got marginal difference with the values recommended by IRC. It is found that with the increase in lane width, speed and radius substantially caused increased in PCU value. Also we developed linear regression equations to estimate capacity and compared those values with the values as we got using Chandra's method. In most of the cases the error is observed to be less than 3%. The percentage error is in the range between 0.02 and 2.41 which is very marginal. Finally from the study it has been observed that increase in lane width and radius at curves obviously increases the capacity their by increases both comfort and safety of the road users.
The primary and most universal measure of all kinds of work by nature is the energy. Coal, Natural gas, Oil and Nuclear energy are net energy yielders and primary sources of energy. The intent of this paper is to assess the performance of 15KW solar power plant installed in Priyadarshini Engineering College (PEC) campus, Vaniyambadi, Vellore District, Tamil Nadu. A 15 kW solar PV plant has been installed to supply electricity to the internet laboratory and library (lighting load). The results obtained from monitoring a 15 KW Solar Photovoltaic system installed on a library roofing of 10m height building. The system was monitored between (July-Sep2016) from 9.30AM to 4.30PM for three days in a week from Monday to Wednesday. The results can be used to provide manufacturers to develop their products and enhance the knowledge in the future in order to improve the design of the off-grid solar photovoltaic system, return of investment during these years. This work focuses on the performance of the solar photovoltaic plant (July-Sep2016) monthly average demand and annual performance parameters, Efficiency, fill factor,capacity Utilisation factor and the characteristics have been plotted in a graph. The graph is drawn between Generated power vs consumed power. The annual yield of the solar photovoltaic plant ranged from 6500-7000 Kwh and performance ratio of 78%. It has capacity Utilisation factor with 6.97%.
