| dc.description.abstract | Traffic engineering used engineering methods and techniques to achieve the safe
and time efficient movement of people and goods on roadways. The safe and time
efficient movement of the people and goods is dependent on Traffic flow, which is
directly connected to the traffic characteristics. The three main parameters of a traffic
flow are volume, speed and density. In the absence of effective planning and traffic
management of the city, the current road infrastructure cannot cater the future needs
of the city. Pedestrian and vehicle volumes have increased significantly in the last
decade due to the change of the economics of the middle-class families. The current
work studies traffic characteristics in the city of Dhaka at one selected priority
junction. In this work emphasis was given on traffic volume and the analysis was
carried out through primary traffic flow surveys at Science Lab to Mirpur Section-1in
Dhaka city. Traffic flow is studied by manual methods. For better understanding of
the present status of traffic flow at the junction, traffic survey is conducted.
Calculation of Passenger Car Units (PCU's) for different vehicle types was provided
by our respected course co-coordinators of the course CE400. With the help of the
data collection, an attempt had been made to understand the traffic patterns during
different time periods. Traffic control at that junction is also dependent on the traffic
flow characteristics. Hence the results from the present study are helpful in
controlling the traffic at the intersection and also in suggesting some of the remedial
measures to improve the traffic safety in the region. Remedial measures such as
widening the road, changing 4-lane to 6-lane or by providing more public transport
can be recommended based on the outcomes of the work. | en_US |
