Carrying out Classified Traffic Count Survey of RHD Road Network of Faridpur Zone, under MDH Circle, Roads and Highways Department From Faridpur to Barishal Direction at the station N-804
The goal of this traffic survey was to collect information that correctly represents the volume of traffic and local traffic conditions. As a result, vehicles were classified into different categories, and they were counted throughout the period.
Analyzing the amount of traffic entails counting the vehicles on the road, tracking their movements, and classifying them according to where they are in relation to each other. It is described as a process for figuring out the amount of traffic that is moving on the highway road at a specific location during a specific time. The amount of traffic is dynamic and changes constantly. The amount of daily traffic varies according to the day of the week.
The manual count is conducted by us for six hours a day for four consecutive days to obtain the traffic volume data. Data is counted by using a hand tally (a tabulated tally sheet was prepared, which comes in handy when recording classified vehicle counts) and manual enumerators. By this method, traffic volume as well as vehicle classification and turning proportions can be obtained. The data can be used immediately after collection. We installed a camera because the volume is very high. Video is captured for twenty-four hours a day, and data is collected later by rewinding. Besides traffic volume, several traffic parameters can be obtained from the recorded video. Data can be cross-checked, and quality can be ensured.
Vehicles have to be recorded according to twelve categories, such as heavy trucks, large buses, cars, motorcycles, and so on. To help with identification, a “Vehicle Identification Sheet” with pictures of typical vehicles in each category is given to us. As a team leader, I provided a copy of this when the enumerator counted the vehicles. There were three enumerators in my group. Every enumerator was appointed to count four categories of vehicles.
There are several types of vehicles available on the Faridpur to Barishal highway road, like cars, trucks, trailers, motorbikes, and so on. Their impact on traffic flow is also varied due to variations in their sizes, shapes, and speeds. It is very difficult to deal with such a variety of vehicles from the design and engineering point of view. That’s why consider the passenger car as the standard vehicle unit to convert the other vehicle classes, and this unit is called the passenger car unit or PCU.

Residential Building Design and Analysis Using ETABS
Residential Building Design and Analysis Using ETABS
My professor exposed me to a lot of practical modelling, analysis, and design work that goes into multi-story structures, as well as different construction methods that are employed in the field. Drawings were created in AutoCAD and analyzed using the program ETABS.
I designed and analyzed a number of residential buildings in Bangladesh (six and four stories). The software, I used for structural analysis and building design, is called ETABS (V.9). A complex but user-friendly application for particular analysis and design was made for building systems. The modelling, analytical, and design processes are all integrated by utilizing a shared database, and it offers a simple yet effective graphical interface. For basic structures, it happens relatively quickly and easily. A grid system defined by horizontal floors and vertical column lines may easily construct building geometry. The majority of buildings in Bangladesh are of straightforward geometry, with horizontal beams and vertical columns.
There are several distinct stages that I followed in structural design in ETABS. I start by looking at the AutoCAD drawing and drafting of the column and beam arrangement plan. The grid line is then imported into ETABS. After that, I created the modelling in ETABS. The qualities of materials are then defined. After that, choose column and beam sizes. Delineating the parts of the wall and slab. Assigning gravity loads, seismic loads, and other load combinations in accordance with the Bangladesh National Building Code is the next stage. Before beginning the analysis, the model's total load combinations were examined. Check rebar percentages and all other parameters after assessing the model to ensure that all design requirements adhere to the BNBC Code.

Determining how congested the traffic is at the major intersections in Faridpur & identify the Level of Service.
Determining how congested the traffic is at the major intersections in Faridpur & identify the Level of Service.
Cities in emerging nations like Bangladesh are particularly concerned about the increase in automobiles brought on by the proportional increase in people and the quick development of contemporary civilization. Therefore, it is crucial to keep an eye on both the number of traffic and the Level of Service (LOS) or quality of the supply of transportation. In the current study, the behavior of mixed traffic flow in Bangladesh's Faridpur city is investigated. In order to assess the degree of service at three significant non - signalized intersections in Faridpur city, a field traffic volume assessment was conducted. Peak hour factor (PHF) technique and volume capacity ratio were used to calculate level of service (LOS). In Faridpur city, the kind of traffic flow is diverse. So, this mixed or heterogeneous traffic is made simpler by the passenger car unit (PCU). Then, LOS was calculated using the estimated PCU. Road surface LOS was computed in both directions. At the crossroads of Janata Bank Mor, Rajbari Rastar Mor, and Bhanga Rastar Mor, auto rickshaws, easy bikes, and rickshaws predominate. The LOS of the Janata Bank Mor intersection is the worst and most unstable according to the PHF and V/C ratio methods. The New to Old bus-stand lane at the three-legged Rajbari Rastar Mor crossroads has the largest traffic flow at peak evening hours, and an analysis using the V/C ratio and PHF approach reveals that the LOS from Bhanga Rastar Mor to Alipur is extremely bad in nature. In light of the findings, it is possible to suggest that Rajbari Rastar Mor crossroads be made truck-movement-restricted during the day and that the width of Bhanga Rastar Mor and Janata Bank Mor residential area roads be raised to improve traffic flow. Additionally, to speed up traffic in the city area, an efficient traffic signal should be included, and traffic laws and regulations should be effectively administered and maintained in the intersection with the worst conditions.
