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.)

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

GEOMETRIC CONDITION

SIGNAL/MARKING : Traffic signs are used to give instructions and provide information to road users.

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.

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.

ISLAND :The front of standard island is circular.

Broken island at Russell’s Square

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…..
