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

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:

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
