3. Introduction
Road Traffic Control Systems collect and analyze
driving information of vehicles in the area, perform the
optimal traffic signal control in accordance with the
constantly changing road traffic situation, and provide
useful traffic information to drivers based on the data
collected.
In this project, there will be discuss about the traffic
control system implies in Dhaka city and how can
improve it with proper solution.

4. Traffic control Devices
In Dhaka city there have mainly
three types of traffic control
devices:
I. Signs
II. Marking
III. Signals

5. Traffic control Devices
Traffic Signs:
Prohibitory sign
Mandatory sign

6. Traffic Control Devices
Traffic Sign:
Informatory Sign
Speed limiting
Warning Sign

7. Traffic Control Devices
Traffic Marking:
Pavement Marking:
Kerb Marking:
3D Zebra crossing in Bangladesh to
control vehicle speed limit

8. Traffic Control Devices
Object Markers:

9. Traffic Control Devices
Traffic Signals:
Traffic light:
A controller is an electrical device located in a cabinet for
controlling the operation of a traffic control signal that
changes
the colors indicated by the signal lamps according to a fixed
or variable plan.
Signal coordination:
Traffic signals coordination was developed using this
system, traffic signals on the same major highway
were linked together using a master timing device or
controller. This was used instead of individual timing devices
at each intersection.

10. Traffic Control Devices
1. coordinated controller system:
2. Computer Based Area coordinated traffic Controllers:

11. Traffic Control Devices
3. Vehicle-Actuated Signals:

12. Traffic Control Devices
Pedestrian Signals:
1. In roadway warning lights:
2. Countdown signals:

13. Traffic Control Devices
3. Accessible signals: verbal/ vibrotactile tone(Push Button):
Bangladesh 1st smart pedestrian
signals which is implemented in
North Dhaka City.

14. Traffic Control Devices
Other control devices:
Speed Hump:
Rubber speed Hump and Bump
Raise Marker in lane Reflective edge marker

15. Traffic Management system
Advanced Traffic Management Systems
(ATMS), which evolved from the field of the
Intelligent Transportation Systems (ITS), stream
real-time transport data from the entire traffic
infrastructure into one Transportation
Management Center (TMC). The TMC
processes the data and takes intelligent actions
that increase transport efficiency, mediate
traffic congestion, and improve safety.
Intelligent Traffic Control System

16. Traffic Management system
2. Video analytics in traffic management:
Advanced traffic management systems stream a live video feed from all major roads into theTMC.
The data can be stored and used for:
• Predictive optimization of traffic
• Detecting traffic jams and taking action to release them
• Detecting and counting vehicles and pedestrians
• Evidence in accidents or traffic law violations.
All insights can be used directly by city officials, and serve as additional data to enable predictive AI
modeling.

17. Traffic Management system condition in Dhaka City
Traffic Department of Dhaka Metropolitan police (DMP) is one of the key agencies of present traffic
management system functioning control of traffic movement in the city, enforcement of traffic rules
to ensure road safety, investigating road accidents, storing of data and the analysis of the accident
data. But The traffic management condition is too much poor. From a well-known online news portal
named Dhaka Tribune their have a study: Dhaka traffic wastes 5 million work hours, costs Tk37,000
crore. There is a dearth of crucial personnel in planning, management, traffic operation, and safety
jobs.

18. Traffic Control System Problem in Dhaka City
In a research, has been see that total of 253 approaches of 70 signalized intersections in Dhaka City
are studied. Detail field surveys are conducted in each intersection, and it is observed that out of 70
signalized intersections 84% are fixed time (FT) signal system. And most of the traffic Signals place
is in wrong place.
Position of Traffic Signal at North
Approach in Agargoan Intersection
Position of Traffic Signal at East
Approach in Banani Kakoli Intersection

19. Traffic Control System Problem in Dhaka City
Signal Light Missing at
Sadarghat Intersection.
Traffic Signal Direction
Wrong at Sadarghat
Intersection.
Traffic Sign Condition at
East Approach in
Rajarbagh Intersection.

20. Traffic Control System Problem in Dhaka City
Faded Road Marking at Pirganji
Mazar Intersection.
Poor Visibility of Signal
Light at East Approach of
Azimpur Intersection.
Signal Pole Location at North
Approach of Bijoy Nagar
Intersection

21. Traffic Control System Problem in Dhaka City
Unrealistic placement of Pedestrian signals:
Nobody Cares about smart traffic push button---tbnews.bd
Pedestrians and drivers cross the street as they wish.
Each time the button was pressed, the green signal was
active for 27 seconds. During the time the green signal was
active, most of the vehicles did not stop as the drivers
continued to drive.
Dhaka North City Corporation recently
introduce push button signal system in
front of the SFX Greenherald
International School in city’s
Mohammadpur for safe road-crossing.

22. Proper Solution of the Problems of Traffic Control System
ITS Status and Implementation Challenges in Bangladesh:
This is a propose project where Intelligent Transport System will be implemented.
Traffic Monitoring System:
1. In 2009 Dhaka Metropolitan Police (DMP) installed the digital surveillance system for traffic
management and crime control
2. Launched a unified control room called C3S (Command, Control and Communication System).
3. Set up more than 100 CCTVs and installing about 31 dot matrix displays at major intersections of
Dhaka
4. It was expected that C3S would be capable of identifying vehicle drivers disobeying traffic rules and
escaping any accident scene or involved in other heinous crimes.
However, institutional issues, such as multiagency coordination and enforcement have prevented the
achievement of expected benefits.

23. Proper Solution of the Problems of Traffic Control System
Traveler Information Systems with
Variable Message Signs (VMS):
1. Providing data for traffic information
services through VMS is important for
traffic.
2. In Dhaka while there are several
locations with a VMS facility, the display
boards often malfunction due to lack of
periodic replacement and maintenance

24. Proper Solution of the Problems of Traffic Control System
Traffic Signal System:
Signal Control Parameter:
Advanced Traffic Signal is controlled by following parameters calculated based on the traffic
volume from the vehicle detector.
Cycle: Time duration that the signal returns back from green to next green through yellow and red.
Split: Time duration of ratio allocated to green.
Offset: Time gap between adjoining intersections to make traffic flow
Smooth.

25. Proper Solution of the Problems of Traffic Control System

26. Proper Solution of the Problems of Traffic Control System
CCTV Camera System:
Targeted Object
• Traffic flow going into the Intersection
Number of CCTV cameras
• 2 cameras diagonally for each intersection
 Monitoring of CCTV images
• Monitoring Place: DMP Command and Control Center (DMP operates CCTV system.)
• Communication Line: Telecom Operator’s Network (e.g. BTCL or Private company)
