OBJECTIVE: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

RUSSEL SQUARE TO PANTHAPATH INTERSECTION
OUR APPROACH:
Data collection:
DATA ANALYSIS:
FROM RUSSEL SQUARE TO PANTHAPATH TWO LANE
FROM PANTHAPATH TO RUSSEL SQUARE THREE LANE
• Width of it this line is 2.1m
• SOLID line can increase driver’s efficiency and freedom• But most of the case it has been used for illegal parking
• CONTINIOUS SHOULDER AND MEDIAN
• Shoulder height and width in average is 1 feet & 1.7m
• Median height and width in average is 1.5 feet and 1.7 meter
• HEIGHT REDUCTION FOR PEDESTRIAN• INCREASED INFLUNCE ZONE
SHOULDER AND MEDIAN:
INTERSECTION:
• Channelization has seemed to be effective as less congestion at those point
• Pedestrian facility in channel is good.Furnished with signal and enough space for pedestrian.
OPERATIONAL:SIDEROAD: • REDUCED safety,
efficiency and capacity• ABOUT ELEVEN IS
PRESENT• Main vehicles emerge
from here is NMV and CNG
• AVERAGE WIDTH VARIES 1 TO 4 METER
EFFECTIVE ROAD WIDTH• On average 3m width has reduced• Reduction in shoulder is on average .4m• Increase in median influencing area is about 6”• Illegal parking, activities and placement of construction material
CONTROL DEVICE: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
ROADSIDE CONDITION:
Chain age distance(upto 250m)

Parking Illegal parking through the road randomly
Vehicle type:
NMV,CAR,BUS
Speed breaker
None
• FREQUENT PEDESTRIAN PASSING FACILITY
• PLACEMENT OF DUSTBIN AND CONSTRYCTION MATERIAL
• ILLEGAL PARKING IN REGULAR INTERVAL
Road surface:• Skid resistance in skid resistance tester 65• Pothole, water blockage ,rutting, distress ,crack are present
Street Lighting:• Average 27.7’• Central• Double arm• Several equipped with solar power
Recommendation for further study:• Before surveying a clear view can be achived from • It is better to choose a holiday and early in the morning for surveying• Again top view gives clear idea about the system.So some of the numerator should choose an
upper place and may guide the others from there.
Recommendation for development of roadway condition:• The main disease is illegal parking. So frequent investigation and enforcement has to be
applied for better traffic condition.• For widening effective width shop and construction material from median and footpath need
to be removed• As commercial buildings are profound we should conduct a survey for stablishing service
road• Traffic markings has to be renewed properly within routine interval• Blocking of channel near channel should be strictly monitored
