Abstract:
The bus is the major mode of public transport in Dhaka city. Despite a high modal
share, bus service quality is poor and para-transit services (taxi, CNG) are
remarked as a problem in metropolitan transport systems rather than a solution.
The study investigates passengers’ perceptions regarding bus service quality in
different areas of Dhaka city and presents a comparative study. The
research identifies and valuation of eight important attributes using the logit model
and compares data obtained from the residential and commercial areas. Attributes
are—Fare Expenditure, Seat Comfort, Onboard security, Bus frequency, Bus staff
Behavior, Interior Cleanness, Route Information, and physical condition. A
question on overall quality of bus service is included in the questionnairesurvey
form for cross validation of the proposed legit model. Besides, general
information is collected for evaluating homogeneity of data size, which included—
Age, gender, Occupation, Monthly income. A pilot survey is performed to test the
questionnaire using a smaller sample compared to the planned sample size to
check the correctness of the questionnaire. A questionnaire
survey is conducted to collect data from 300 respondents. The legit model is a
classifier to describerelationship among dependent variables with independent
attributes or features. SPSS v. 24.0 isused to develop legit model for the modeling of passengers’ perception regarding bus service quality. Two models are
developed where Model 1 is a full model with all eight attributes and model 2
consists of four attributes, those are-- Fare Expenditure, Interior Cleanness,
routes information and Physical condition. Model 1 and Model 2 predicts with
72.3% and 69.7%accuracy. Model 1 and Model 2 have 46% and 41.4% variability
of survey data respectively.Model 1 indicates that the order of influence of
attributes relate to overall condition are interiorcleanness, structural condition,
fare expenditure and route information. Model 2 displays that theorder of
influence of attributes relate to overall condition are interior cleanness, fare
expenditure,Structural condition, and route information. Overall condition scored
2.97 which is slightly below average.
