Item Analysis of Transport Mode Choice in Kathmandu Valley, Nepal: Lessons from Trondheim, Norway(I.O.E. Pulchowk Campus, 2022-09) Adhikari, AashishTransportation Planning is essential as it is a basic foundation of society linked with mobility and several domains of environment and sustainability. An important aspect of urban transportation planning is travel demand analysis, particularly mode choice modeling which helps in understanding the decision-making process which is a need for creating suitable actions for achieving sustainable mobility by creating factors that can motivate individuals to avoid-shift and improve different modes of transportation. This paper uses both quantitative and qualitative methodologies for analyzing how different modes of transportation are used and their relationship with infrastructure which influences the particular mode choice along with studying the relationship between mode choice and land use attributes. A case study approach was taken from where different lessons were drawn. The results can show an analysis of different modes of transportation and their usage with the reason for particular mode selection along with mode shift parameters and the influence of infrastructure on particular mode choice. The research generates different conclusions and implications comparing different modes and can be used as a reference for further research on travel behavior and mode choice.Item Impact Analysis of Electric Vehicles on Distribution System (A Case Study on Patan Feeder, Pulchowk DCS)(Pulchowk Campus, 2021-09) Shrestha, RabinWith the vision of reducing the dependency on petroleum products for transportation and maximize the consumption of electricity generated, the Government of Nepal GoN and NEA has set up plans to encourage the use of Electric Vehicles (EVs). EVs not only reduces the consumption of petroleum products for transportation but also helps in pollution free transportation. In order to compete with petroleum-based transportation, NEA has plans to set up EV charging station as many as possible. The increased number of charging station will increase EVs in the Distribution System. In this study of Impact Analysis of Electric Vehicles EVs on Distribution System, the effect of different penetration level of EV battery charging on Distribution System is analyzed. This research presents a methodology for modelling and analyzing load flow and harmonic analysis in a distribution system due to EVs. This study focuses on voltage deviation, line loss and total harmonic distortion caused due to different penetration level of EVs in the Distribution System. Due to ever increasing use of electric vehicle in the world, an electric utility must be able to meet the both energy demand and peak demand caused by charging of EV’s. Not only the peak demand and energy demand fulfillment, a utility must be able to maintain its THD within prescribed limit. So, in order to make the system healthy, the supply side of EV battery charging circuit must be harmonic free. For the study purpose ETAP software is used and impacts on Patan feeder, Pulchowk DCS of NEA are studied on different cases of load periods and with and without EV penetration as well. As the selected feeder comprises of two charging stations and transformers capacity of 200 kVA and 1000 kVA, impacts are studied based on the charging stations operating individually and simultaneously. Voltage Deviation and Line Loss are found to be increased at peak demand period with the increased EV penetration while THD is found to be increased at off peak period with the increased EV penetration. This is because at off peak period, with the increased EV penetration, the EV load is very high and the use of converters becomes high. Voltage Deviation and Line Loss goes on increasing with the increase in power demand even without EV Penetration. Maximum Voltage Deviation is 4.82% at Labim Bus at peak demand period. Line Loss is maximum at peak demand period of 102 kW. Maximum Voltage Deviation is 5.83% at Labim Bus at 100% EV Penetration during peak period and Line loss 121 kW, which is also highest at the same period and same penetration level when both Sajha and Labim Mall Charging station are operating simultaneously.Item Problems and Prospects of Tourism in Kailali District: A Case Study of Darakh VDC(Department of Rural Development, 2016) Singh, Dipendra BahadurA thesis entitled "PROBLEMS AND PROSPECTS OF TOURISM IN KAILALI DISTRICT: A Case Study of Darakh". The objective of the study is to identify the problems and prospects of tourism in Darakha VDC of Kailali district. This study is limited in Darakha VDC in Dhangadi district. This study is mainly concerned with the existing and important tourist spots, tourism trend, prospects and problems of tourism in study area. This study has applied explanatory and descriptive research design. The data is qualitative as well as quantitative in nature. Out of 50 respondents including national and international tourists from different countries was taken 45 respondents by using random sampling. My study concluded that Darakha area have huge potentiality of rural tourism. This area is easily accessible as because it is just one and half hour away from headquarter Darakha. Tourist can get the Green community forest can be another reason for visiting this place where tourist can find small religious spot with interesting myth behind that place, where organization of old people with their own fund and effort have been making water tap so that passerby can enjoy the cool drinking water. There are different challenges which stand as hindrances in the pace of tourism development in this area. One of the major problems of this area is that this area have road track. Lack of total participation for the tourism development is another problem of this area, some organization lacks co-ordination for conducting different tourism development activities. Lack of young manpower involvement is another major problem, as most of the young manpower area involved in abroad job, some are in headquarter of the district, Nepaljung and Kathmandu for educational purposes and for job. This place is not properly advertised in media and also it lacks link with the NTB in order to get proper support from state sector.
