PRESENTATION SYNOPSIS
INTRODUCTIONOBJECTIVE OF STUDYSCOPE OF STUDYMETHODOLOGYDATA COLLECTIONDATA & PHOTO ANALYSISRECOMMENDATION
INTRODUCTION
The methodology used for preparation of Road Condition is called Road Way Condition Survey.
A condition survey is the process of collecting data to determine the structural integrity, distresses, skid resistance, and overall riding quality of the pavement.
OBJECTIVE OF STUDY
To draw detailed layout of roadway and intersection.By qualitative observation of potholes,
elevated/depressed manholes, speed breakers etc.To determine loss of effective width at different
locations due to loading/unloading, illegal parking, construction utility etc.
To show various control devices like Road sign, Marking, Signal, Speed breaker, Street light etc.
To find density of road obstructions (manholes, speed breakers, potholes etc.)
DESIGN AND PLANNING PURPOSE
IMPROVEMENT PURPOSE
DYNAMIC TRAFFIC MANAGEMENT AND PRIORITY SCHEDULE
ACCIDENT RATE COMPUTATION
SCOPE OF STUDY
METHODOLOGYROADWAY CONDITIONMANUAL METHODo Walking surveyo Windshield surveyo Walking and windshield surveyAUTOMATIC METHODo Video camerao Distance measuring instrumento GIS methodo Automated road analyzer
MANUAL METHOD
WALKING SURVEYo Done by a walks
down the side of the pavement.
o Provides the most correct data.
o Time consuming.
WINDSHIELD SURVEYo Systematic
observation made from a moving vehicle.
o Useful when particular section of road segment is observed.
o Time saving.
WALKING AND
WINDSHIELD SURVEYo Better method than the
single application.o Achieve maximum
pavement data and complete pavement surveys.
o Require both technological and human activity.
AUTOMATIC METHOD
VIDEO CAMERAo Observe service
condition.o Attached on the post in
the street.o Doesn’t work at night.
DISTANCE MEASURING INSTRUMENT
o Electronic instruments that precisely measure distances ranging from 10s of feet to thousands of miles.
o They are easy to install.
GIS METHODo GIS is a system designed
to capture, store, manipulate,analyze, manage and present all types of geographical data.
AUTOMATED ROAD
ANALYZERo Technically complex
vehicle.o Have sensor machine
attached.o Take photo as well as
distance.

DATA ANALYSIS
Panthopath to Russell’s Square road

Russell’s square intersection
GEOMETRIC CONDITION
SIGNAL/MARKING : Traffic signs are used to give instructions and provide information to road users.
Traffic signal Traffic marking
Standard traffic signal Standard traffic marking
Cautionary sign
ROAD SURFACE MARKING : Road surface marking is any kind of device or material that is used on a road surface in order to convey official information.
Road surface marking
Standard Road Surface Marking for pedestrian crossing
Standard Road surface Marking
MEDIAN : Median is a narrow area of land that separates the two
sides of a big road in order to keep traffic travelling in different directions apart.

Median in developed country
ISLAND :The front of standard island is circular.
Broken island at Russell’s Square
Standard island in developed country
SURFACE CONDITION
Potholes and unleveled roadway condition at Panthopath road.
Damaged and broken roadways
Cracking and rutting on the surface
OPERATING CONDITION STREET LIGHT:
In Panthapath to Russel Square the street lights condition are not well managed.
Street light at Panthopath Street light in developed country
UNUSUAL CONDITION OF ROADWAY :
Unusual Bollard in poor condition
Sludge on the roadway
Illegal parking
Sometimes law protectors break the law
FOOTPATHS : Hawkers occupied the footpath at most place which causes
blockage on the footpath.
Shops and construction materials occupy the footpath
Electric pillar and parking on footpath
People walking through roadway
UNCLEAR SIGN CONVENTION :
RECOMMENDATIONS The surface of roadway was not good enough and the medians were not
geometrically right. The marks on the road were invisible. So our recommendation is that we should be careful about regular maintenance of road.
The signs we observed on the roadway were old and not only covered by posters but also broken. So replacing these old sign plates with new ones is highly recommended.
We found different kind of small shops on the footpath/shoulder. So it is recommended that Dhaka City Corporation should take essential step to clear the footpath so that pedestrian can move easily.
There were no facilities for blind people and people who use wheelchair. So extra facilities for these people are recommended.
According to recommendation a complete roadway should be as…..
