All praise goes to almighty Allah, the most merciful and the most benevolent. First of
all I want to pay my gratitude to my thesis supervisor, Dr. Farzana Rahman for
providing me continuous support and guideline to perform this research work and to
prepare this concerted dissertation. Her contribution to me can only be acknowledged
but never be compensated. Her consistent inspiration helped me to work diligently
throughout the completion of this research work and also contributed to my ability to
approach and solve a problem. Without her continuous guidance this dissertation
would not have been materialized. I would like to express my deepest gratitude to the
Department of Civil Engineering, specially Brigadier General Md Wahidul Islam,
SUP, ndc, psc, Dean and Head, Department of Civil Engineering, Military Institute of
Science and Technology for giving me such a great opportunity of doing my M.Sc
Engineering and this contemporary research work.
I am indebted to my family members for their continuous encouragements,
cooperation and mental support. Their support and cooperation were indispensable. I
express my heartfelt thanks and gratitude to my wife for her persistent cooperation to
my works.
At last I want to thank my department, the respected members of my examination
board for giving me such an opportunity, which has obviously enhanced my
knowledge and skills as a transportation engineering student to a great extent. |

Mode choice and trip chaining behavior of developing cities are becoming more complex
gradually due to rapid urbanization and economic growth. This thesis is aimed to determine
the major factors that affect the mode choice for work trips in Dhaka city by structural
equation model (SEM). A two-step methodology has been adopted for this research. The first
part addresses data collection approach incorporating a purpose built questionnaire survey
and the second part is to develop SE Model. A questionnaire survey was conducted at 14
locations of Dhaka City. A total of 1000 work trip makers were interviewed. Four different
models are developed to find out the correlation between mode choice attributes and effects
on overall mode choice. For each model there is a shuffling of exogenous, endogenous and
latent variables to examine models for better results. A two tailed test is used for analyzing
the parameters with a critical value of 1.96 for 95% confidence limit. For the final proposed
models, it was revealed that all endogenous variables are positively related with latent
variables. Out of four models, the best one is selected based on statistical parameters and
resemblance with real life anticipations. Two latent variables trip chain, trip behavior and 14
endogenous variables have been considered in model 4. The result shows that among all
attributes, waiting time at station, time taken to reach destination, comfort level of the mode
and travel by bus/tempo having coefficient values 0.67, 0.33, 0.86 and 0.88 respectively
influence users’ choice of mode significantly. “Simple home to work and work to home” type
trip chain has positive effect on the latent variables. It was found that fit indices of the best
model are within the range (CFI=1.00, RMSEA=0.000, SRMR=0.000), indicating a good
model. The results match with real world scenario. Results of this research are expected to
help transport planners to understand mode choice and trip chaining behavior and facilitate
development of relevant transportation policies of assessing infrastructure investment. |
