4. Roadway condition is an important parameter in selecting things for
improving vehicular movement in a road or highway. Sometimes
roadside use pattern in our country affects the traffic stream and the
smoothness of their passing in the road.
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.
INTRODUCTION

5. OBJECTIVES
Observing:
Geometric Condition
Operating Condition
GEOMETRIC CONDITION
 Geometric layout of
roadway
 Geometric layout intersections
 Surface condition
OPERATING CONDITION
 Location and width of side roads
 Road side land-use pattern
 Loss of road width
 Pedestrian crossing facilities
 Locations and type of control devices
 Layout of street lighting system

9. WALKING SURVEY
Done by a walks down the side of the pavement
WINDSHIELD SURVEY
Systematic observation made from a moving vehicle, time saving.
WALKING AND WINDSHIELD SURVEY
Better method than the single application, require both
technological and human activity.
MANUAL METHOD

11. AUTOMATIC METHOD
VIDEO CAMERA
Observe service condition.
Attached on the post in the street.
DISTANCE MEASURING INSTRUMENT
Electronic instruments that precisely measure distances ranging
from 10s of feet to thousands of miles.
They are easy to install.
GIS METHOD
GIS is a system designed to capture, store, manipulate, analyze,
manage and present all types of geographical data.

13. Study Site

14. Location: Panthapath-Russel Square Road(just opposite of Samorita
Hospital)
Date: 23/3/17
Day: Thursday
Status: Working Day
Time Schedule: 8am to 12pm
Weather condition: Sunny, partially overcast
Temperature: 32˚C
Equipment: Tape, Odometer, Skid Resistance Tester etc.
Method: Manual
Condition of Site

15. Data & Photo Analysis
HEAVY
TRAFFIC.
 TRAFFIC IS
CONTROL BY
THE POLICE
MAN.
PEOPLE ARE
MOVING
FREQUENTLY
VEHICLE IS
MOVING
Intersection

17. Traffic Signal:
All types signal are present here.
But they are not operative.
Again manual control is dominant.
Markings:
In several places has worn out.
Tiger marking, lateral and parallel markings were there.
Violation of markings are frequent.

18. Road surface:
Skid resistance in skid resistance tester 65.
Pothole, water blockage ,rutting, distress ,crack are present.

19. Street Lighting:
 Central
 Double arm
 Average 27.7’
 Several equipped with solar power

21. Pedestrian Behavior:
Unawareness and lack of facilities disrupting the roadway
condition

23. Recommendations
 A ‘windshield survey’ would also have generated better results, & led to a more
detailed conclusion.
 Removal of potholes for the free flowing vehicular movement is important for
increasing travel speed & decreasing travel time.
 Road surface, markings and signs should be well designed and maintained
 Law enforcement agency be more active in enforcing traffic.
 Raise awareness among pedestrians about road safety and encourage them to
use footpaths in a regular and orderly manner

24. Limitations
Resource Constraints
Unskilled surveyors
Manual method of walking
Inadequate funding to run the survey
Lack of modern instruments
Not having a professional photographer
