MAT.pdfThis is my first journal article as a main author in MAT Journals Entitled "Critical Gap Distribution Estimation for Different Types of Vehicles in Rajshahi City, Bangladesh" published in 2023. This article examines the impact of traffic volume and geometrical features on the crucial difference between capacity and delay at unsignalized junctions in Rajshahi, Bangladesh. The study, conducted in Sagorpara Bot-tola, the busiest junction, gathered 659 data points for three vehicle types: 2-wheelers, 3-wheelers, and 4-wheelers. The current state of two- and three-wheeled private and shared automobiles in the city is concerning, as intersections can no longer accommodate large volumes of vehicles, leading to peak-time traffic gridlock and travel delays. The Maximum Likelihood technique was used to estimate crucial gaps in complicated traffic conditions. The model found crucial distances between 6.97 and 4.29 seconds for vehicle drivers, 6.73 and 4.4 seconds for two-wheelers, and 6.73 and 4.4 seconds for three-wheelers. The suggested strategy demonstrated its ability to distinguish between cars with two and three wheels.

40-51BUSServicePaper1.pdfI am delighted to share that my latest journal article, "Passengers Satisfaction Level on Bus Services in Chittagong City Using Multiple Linear Regression," has been published in MAT Journal! ππ
This research dives into the key factors influencing travelers' satisfaction with bus services in Chittagong city. Proper travel satisfaction hinges on various journey and vehicle-related aspects. Our study examined factors such as fare pricing, journey frequency, reasons for travel, delays, driver skills, vehicle fitness, seating conditions, cleanliness, and staff behavior. π§³π
We conducted a comprehensive survey, collecting 451 samples from 10 different locations in Chittagong city to analyze the transportation conditions. The study aimed to determine the quality of bus services based on these factors using a Multiple Linear Regression Model. ππ Key findings reveal that ticket cost, delays, crowdedness, and fare pricing negatively impact overall satisfaction, while journey frequency, service frequency, seating conditions, and staff behavior positively influence satisfaction. Crowdedness has the strongest negative impact, emphasizing the need for efficient service frequency to reduce waiting times. β³πOur study provides valuable insights for city planners, aiming to enhance bus services and transportation in Chittagong, ultimately contributing to economic improvement through smoother travel experiences. This research highlights the importance of understanding consumer perceptions to make informed decisions for better service quality. ππ
