RECOMMENDATION
3
The methodology used for preparation of Road Condition is called Road Way Condition Survey.
Roadway Condition Survey will indicate the process to determine its surface, side and overall workability as per the demand of land use.
The Road- traffic system is a complex joint of 4 components- road, vehicles, road users & environment.
4
To draw detailed layout of roadway and intersection. To find road length, numbers of lane, median height
and width, shoulder height and width etc. Dimension and location of pedestrian refuge. Roadside land use pattern . To show various control devices like road sign,
marking, signal, speed breaker, street light etc. To find density of road obstructions (side roads,
manholes, speed breakers, potholes etc). To plan for reducing time in intersection. For betterment of existing situation of our study.
5
Provide general information of road width, lane quantity and width, surface quality, vehicle, pedestrians.
A uniform rating system for each side.
A means to monitor the condition of any section of pavement.
Improvement purpose.

FOOTPATHS
Footpaths are blocked by small stores & heavy machines.
24
Some Major Problems
Broken bricks create obstruction on the road.
25
Some Major Problems
Illegal occupation by the rickshaws.
26
Some Major Problems
V notch & signals on intersections are blocked by signboard and tree.
27
Some Major Problems
Open gathering of garbage and construction materials on the road being
obstruction for people and vehicles.
28
Some Major Problems
Construction materials on the road blocking considerable space.
29
Some Major Problems
Erosion of constructed manhole surface creating danger for people & vehicles.
30
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.
