Title: Analysis of Pedestrian Behavior in Complex Interaction with Autonomous Vehicles

Brief Description:

The goal of this project is to evaluate and quantify pedestrian behavior and its trajectory by using pedestrian motion model and simulations. The motion model can help to understand different perspectives from pedestrian viewpoint and what factors are related to the safe interaction between AV and pedestrian. These factors can be varied based on individual pedestrian characteristics, vehicle’s parameters, road’s parameters etc. The Scenario-based approach using probabilistic risk assessment with respect to vulnerable road users’ safety will also be conducted. Impact force on pedestrian coming from AV will be measured during the case of actual AV-pedestrian collision and injury assessment will also be done in this high-risk conflicting scenario.

Title: Evaluating Comfort for Public Buses in Dhaka City

Brief Description:

A micro controller made by Arduino with attached sensors is used to measure the comfort level of public buses in Dhaka city. The senors measured the temperature, sound level, acceleration, jerking and GPS location of a specific bus journey. Questionnaire survey of the bus passengers was also done. Then a multiple linear regression model was made considering both mechanical data and qualitative data. This research leads to a prime finding that comfort level at public buses in Dhaka are ‘slightly uncomfortable’ or ‘uncomfortable’. It also signifies the impact of temperature and jerking on the overall comfort feeling in public buses.

Title: Evaluation of Public Bus Comfort Considering Socio-Economic, Demographic and Trip Attributes.

Comfort of public bus in Dhaka city was evaluated considering Socio-economic, Demographic and Trip attributes. An Structural Equation Model (SEM) was built by R programming. Additionally, Ordinal Logistic Regression was also done by SPSS.
