We have been supporting final year project team of engineering colleges to develop their final year project into wider research project on contemporary transport related issues. Two trilateral MoUs have facilitated such support to the students of Kantipur Engineering College and National College of Engineering.
As a part of the MoU, our partner Picasso Consultant P. Ltd. has assured financial and technical support to not only transport related projects, but also to all other projects willing to extend their scope and research.

Population of Kathmandu Valley is increasing day by day as it is the center of attractiondue to presence of facilities such as education, health, employment, opportunities, etc. People travel to Kathmandu from outside the valley seeking these facilities. Consequently, the population is growing rapidly and there is unmanaged vehicular growth, which is leading to various traffic problems such as undesirable level of congestion, pollution, safety problem, delay (operational and intersection), etc. Different modes of public transportation such as buses and micro buses have been in the valley to serve as the public transportation. Increasing use of the private cars and two wheelers has led to increasing accidents, congestion, pollution (noise and emissions), and social exclusion. Sajha Yatayat is one of the Public Transport intended to provide service inside the valley.
The study team has an aim to cost optimize the service of Sajha Yatayat in route connecting Lagankhel with Budhanilkantha. Along the study, measurement of the present situation of the travel demand along the route is performed through different modes (Public and Private modes). The impact of the Sajha Yatayat in environment (emission analysis), its fuel analysis is performed for “if all replaced” for present travel demand on the route. The data for this study was obtained from the various resources, taken as in term of the primary and the secondary data.

The traffic system needs to be properly managed else it could bring out losses through crashes andcongestion. Intersection, one most critical section of road, needs the proper management. This report is prepared for the analysis of the newly installed traffic signal system at Baneshwor, Nepal. The signal in Baneshwor intersection was installed in 2074, Chaitra 14.
Baneshwor is regarded as one of the most important area with the view of commerciality and development. Moreover other important government offices are also nearby this intersection so it needs to be well managed. This report is prepared to find out the capacity of the intersection and the new convenient signal timing with the 15 minutes classified traffic volume from manual method of counting. The count was done for 4 days that included 3 days weekdays and a day Saturday. The count was done for 2 hours in morning and evening and an hour at day time while for Saturday, it was an hour count for morning, evening, and daytime.
The total volume in form of PCU was calculated for each direction of the intersection. Then the left turn and right turn proportion were determined. The heavy vehicle proportion was too calculated. Then the data stated above were applied to find out the saturation flow rate . The base saturation flow rate (S0) for standard lane was taken as 1900 PCU/hr/green/lane. Then as per stated in HCM 2000, different adjustment factors were considered for the calculation of saturation flow rate. Then knowing the values of volume per hour, capacity per hour, cycle length & green time and calculating control delay, LoS was calculated.
The signal timing design was done using Webster method. The value Q/s was calculated for all phases. Then the loss time per cycle is calculated followed by optimum cycle. The green timing was calculated as stated by Webster method. This intersection deserves a better attention as the pedestrian volume crossing the road in this intersection is high and deserves the necessary consideration while designing the signal.
