5. INTRODUCTION
A ROADWAY CONDITION SURVEY IS DONE BY VISUAL
INSPECTION OF A ROADWAY. A ROADWAY CONDITION SURVEY IS
THE PROCESS OF COLLECTING DATA TO DETERMINE THE
STRUCTURAL INTEGRITY, DISTRESSES, SKID RESISTANCE, AND
OVERALL RIDING QUALITY OF THE PAVEMENT.

6. OBJECTIVE OF STUDY
 To draw detailed layout of roadway and intersection.
 For qualitative observation of potholes, elevated
or depressed manholes, speed breakers etc.
 To determine loss of effective width at different
locations due to loading or unloading, illegal
parking, construction utility etc.

7. SCOPE OF THE STUDY

25.  Road side land-use pattern
The roadside land use pattern is highly dense with commercially developed area including Bank, Hospital
, School, Market, Shopping Mall, Showrooms etc. in the range of 2 storied up to 24 storied.

27.  Loss of road width
 Due to Parking & Parking Barrier

28. • Due to Passenger Loading/Unloading , Para transit & NMV Activity

29. • Presence of Dustbin/ Trash Disposal & Construction Materials

30. • Cutting , Digging ,Repair & Maintains work & Some Illegal
Activities

31.  Pedestrians Crossing Facilities
 Opening Median
Due to facilitate the pedestrian crossing, opening was
provided on top of the median at some intervals in
the mid block section. Near panthapath signal median
height was found to be approximately 20 inch. For
facilate as a pedestrian refuge ,this height was
reduced to 4-5 inch.

32. • Pedestrian Refuge
Besides near intersection and opening of the road, to facilitate the pedestrian
crossing, pedestrian refuge was provided.

33.  Location & Types of Traffic Control Device
 Road Sign & Marking
 Sign :Traffic signs or road signs are signs erected at the side or above roads to
give instructions or provide information to road users. In our survey road we
found sings in both intersection.

34.  Marking
Types of marking
Centre Line, Pavement Edge Lines, Stop Line, Pedestrian Crossings, Word
Marking/Message, Divisional Arrow

35. • Signal
Traffic signs control the flow of traffic, warn you of hazards ahead, guide you to
your destination, and inform you of roadway services.
 Primary traffic signal

36.  Secondary traffic signal
 Tertiary Traffic Signal

37.  Special Filter Signal
o Pedestrian Crossing Signal
o Timer signal

38.  Layout of Street lighting System
 Sodium Light Center, Two head/Double arms
 Solar Panel Light

 Detailed Layout of Roadway & Intersection
Layout of Roadway, where geometric alignment and side roads are shown

40.  Layout of intersection
Panthapath intersection’s
layout when East-West &
North-South traffic flow
occurs. And also conflict
are shown

41.  Stages of traffic movement at Panthapath Intersection
Three Stages Flow
 Stage 1
 Stage 2

42.  Stage 3
 Stages of traffic movement of Russell Square Intersection
Here Also three stages traffic flow occurs
 Stage 1

43.  Stage 2
 Stage 3

44.  Location of Bottleneck
 Due to indiscriminate bus stopping/Stand in both intersection bottleneck is
arises

45.  Due to Littering-car parking through the roadway bottleneck causes though the
roadway
 At side roads opening bottleneck causes

46.  Para transit & NMV activities in front of commercial centers like Hospital, Shopping
mall and also opening of side roads Bottleneck creates.

47. Due to cracking of edge road bottle neck also arises.

48.  Road Light Alignment
 Sodium light layout system mostly common in Dhaka city. The clear distance
between two street lights post or lamp post are approximately 100 feet. Total
number of street light found was 33.Through the roadway
 We also found some Solar panel
Light System which may provided by
Sponsor's in front of Square Hospital.

49. Control Device
Some of Control device found through the road way.
Pedestrian Crossing Signals found in both intersections

50.  Density of Side Friction’s
Different feature of roadway Bottleneck Cause Direction
E-W W-E
Density of side road 8 11
Density of opening 2 2
Density of Pedestrian crossing in median 24 24
Density of Street light 33 33
Density of Manhole 9 15
Density of Dustbin 0 1
Density of Bus stops 0 1
Density of speedbraker 0 0

51. Some other obstruction on the main road are indiscriminate goods loading and unloading
on the road, disturbed traffic flow due to non motorized vehicles entrance like rickshaw,
van, cycle and presence dustbin on the road. It should be must monitored
Loading or unloading goods Non motorized vehicle Dustbin blocks almost one
road lane

52. Erased road marks at intersections at channel head, Line Division, and
pedestrian crossing & Leder crossing signs are erased, invisible traffic
signal can create problem.
They must be monitored
Erased road marks/Sign at intersection At Channel Head

53. Invisible Leder crossing Invisible Pedestrian crossing
At intersections the Ghost islands are blocked or not facilities the
pedestrian and its head are broken

54. Road sign’s are covered by poster or erased and broken or disable street lights are
present in roadway . Some V-notch’s are broken & V-notch sign & marking are erased
Covered & Erased Sign & Slotted Sign Unmarked V-Notch

55. Surface condition of the road is not fair enough due to various kinds of
road cracking which decreases the skid resistances of the road and of the
road way
fatigue crack Ravelling

56. Some traffic law breaking

57. 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 to avoid unwanted incidents such as accidents.
 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 or 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 ,people who use wheelchair and people who are not normal. So
extra facilities for these people are recommended.
