This document provides details about a roadway condition survey conducted by a group of 8 students. It outlines the objectives, methodology, data collection process, analysis and findings of the survey conducted on Panthapath Road between Russell Square and Green Road intersections. The survey assessed both the geometric design and operating conditions of the roadway. Key findings included issues with the design of intersections and channelizing islands, presence of cracks and bottlenecks, poor condition of signs, markings and signals. Recommendations provided focused on improving signs, pavement markings and addressing bottlenecks.

4. 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.

5. PURPOSE OF ROADWAY CONDITION SURVEY
 Evaluate the current condition of the network.
 Roads future conditions.
 Determine maintenance and rehabilitation
needs.
 Determine the costs of repair.
 Prepare plans for repairs.

6. GENERAL OBJECTIVES OF ROAD WAY CONDITION
The roadway condition study is undertaken the
following objectives.
Geometric condition
Operating condition
Geometric condition is divided into two parts. They
are
For Roadway
For Intersection

7. GENERAL OBJECTIVES OF ROAD WAY CONDITION
 For Roadway
 Road Width
 Road Length
 No. of Length
 No. of Lane
 Shoulder height and width
 Median height and width
 For intersection
 Geometric measurement
 Position of Channel/Islands
 Dimension and Location of Pedestrian Refuge

8. GENERAL OBJECTIVES OF ROAD WAY CONDITION
 OPERATING CONDITIONS
 Location and widths of side roads.
 Roadside land use pattern.
 To show location of bottlenecks.
 To show various control devices.
 To find density of side roads.
 To plan for reducing congestion and minimize delay time in intersection.

9. Methodology
Survey can be done by two different ways:
1. Manual Survey
2. Vehicle Based Automatic Survey

10. 1. Manual Survey
There are three types of survey
Walking survey
Windshield Survey
Combination of Walking Windshield Survey

11. A. WALKING SURVEY
Walking surveys are completed by a rater who is trained to rate distresses
according to the agency’s distress identification specifications.
Equipment for Walking Survey:
Figure : Odometer Or Meter Tape

12. WINDSHIELD SURVEY
Windshield survey is completed by
driving along the road or on the
shoulder of the road. The pavement
is rated by a rater through the
windshield of the vehicle.

13. B . VEHICLE BASED AUTOMATIC SURVEY
Types :
Deflectograph - to measure the strength of the road structure
SCANNER - to identify surface defects
SCRIM - to measure the skidding resistance of the road surface

14. RECONNAISSANCE SURVEYS
 Reconnaissance survey and route alignment survey was carried out to acquire
generalized idea about the survey area.
 This survey ensures the physical properties of location which cannot be
authenticated by Google Earth Maps.

15. Study Zone:
Panthapath Road Segment between Russell Square and Green road-Panthapath Intersection

16. DATA COLLECTION
Survey Date : 24 DECEMBER, 2O14
Survey route : Russell Square to Panthapath
Method : Photography survey method(Manual Walking)
Equipment : 15 meter tape and 30 meter tape

Geometric Layout of the Roadway : Geometric Layout of roadway include Road
length , width, no of lanes, median height, width, Shoulder height, width etc.

CHANNELIZING ISLAND ARE INCORRECT .

Distortion of road side

34. SIDE ROAD :

35. BOTTLE NECK :
A traffic bottleneck is a localized disruption of vehicular traffic on a
street, road, or highway. As opposed to a traffic jam a bottleneck is a
result of a specific physical condition, often the design of the road,
badly timed traffic lights, or sharp curves. They can also be caused
by temporary situations, such as vehicular accidents.

36. OBSTRUCTION OF BOTTLE NECK :
U-turn of vehicle create
bottleneck
: Parking at the Exit point may create
bottleneck condition of a Roadway

37. LOSS OF ROAD WIDTH :
Loss of width due to parking
Tea stall beside the road

48. POOR CONDITION OF STREET LIGHT

49. DISCUSSION ON GEOMETRIC AND OPERATING
CONDITIONS
•Both Intersections established without maintaining any geometrical design condition.
•Traffic time cycle is not properly implemented here. That’s why creates congestions
on the road.
•The collector road was poorly designed, the road width and height are not properly
maintained.
•Divisional and Directional islands are totally damaged and used for bothering things.
•Divisional island is fenced by barbed wire which is very harmful for health
•There are unnecessary openings at median.
•The traffic signal was designed by traffic lights , but traffic congestion makes them
worthless. So, the signals are not used currently.
•There are different types of cracks on road, which makes the road unsafe for the road
users.The road side condition is very foul and disturbing. Here is an example of
dustbin. Threre are many points on the road where road is filled with many foul things
. Road-side condition of the road is not up to mark. Both side median is sized by the
street hawkers. Construction material of the building is placed on the median.
Pedestrian is moving on the road.

50. RECOMMENDATIONS
•Signing:
Doubled up (left and right) signing
Oversized signing with high-intensity fluorescent sheeting
Advance Street Name signs (W16-8) on Intersection Warning signs
Retroreflective sign post panels
Solar-powered, sign-mounted beacons
Replacement of additional safety related signs (e.g., Do Not Enter, One Way, etc.)
within 500 feet of the intersection
•Pavement Markings:
Properly placed stop bars (4'-8' offset and perpendicular to the mainline)
Dashed edge lines to delineate the mainline and turn bays and establish points of
conflicting traffic
Lane arrows and word messages in accordance with standard drawings, general notes
and specifications
Addition of crosswalks
