16. Manual Method: Indirect
This method data can be
collected by using portable
counters, permanent
counters, video camera
etc..
It has overcome the
drawbacks of direct
method. But data cannot
be obtained immediately
in this method.

According to this
classification of
Level of Service,
estimated Level of
Service during
survey period was
‘C’.

38. LEVEL OF SERVICE
FINDINGS:
THE SERVICE FLOW RATE IS 836.7 PCU/HR WHICH MEANS THE LOS
OF ROAD IS “C”.
 THE COLLECTOR ROAD IS DESIGNED BASED ON TAKING LOS IS GOING
TO “C”. HERE THE LOS OF THE ROAD IS FOUND THE SAME ON THE
OFF PECK HOUR.
 CAPACITY OF ROAD IS ABOUT 75%.
 DESIRE SPEED IS LESS THAN OR EQUAL TO 50 MPH.

43. FLOW FLUCTUATION
Findings:
 FROM THE RESULTS FLOW FLUCTUATION CURVE IS INCREASING WITH
RESPECT OF TIME.
 AT 11.00AM TO 12.00PM THE BOTH SIDE TRAFFIC FLOW IS GOING
TO TOP MOUNTAIN.

44. RECOMMENDATIONS FOR VEHICLE
COMPOSITION
 INTRODUCED OF PUBLIC TRANSPORT IN A LARGE SCALE.
LIMITED USE OF PERSONALIZED VEHICLES.
NON-MOTORIZED VEHICLES USED SHOULD BE RESTRICTED.

45. RECOMMENDATIONS FOR LEVEL OF SERVICE
 FOR BETTER LEVEL OF SERVICE RESTRICTIVE AND CONTROLLING
MEASURES IS NEEDED
 CROSS-SECTIONS ELEMENTS, PARKING AREA, SHOULDER ETC SHOULD
BE TAKEN IN PROPER MEASURES.

46. RECOMMENDATIONS FOR DIRECTIONAL
DISTRIBUTION
DIRECTIONAL DISTRIBUTION VALUE IS SHOULD NOT GOING TO
DEVIATED FROM DESIGN VALUE
THE VALUE SHOULD BE IN 55%
 IN EVENING THE DATA IS GOING IS REVERSED.

47. RECOMMENDATIONS FOR FLOW FLUCTUATION
FOR GETTING AN ACCURATE FLOW FLUCTUATION CURVE THE WHOLE
DAY’S DATA IS NEEDED.
 FOR GETTING AN ACCURATE FLOW FLUCTUATION CURVE, %ADT IS
GOING TO NEEDED TO ACHIEVE A BETTER RESULT.

48. LIMITATIONS
TIME AND RECOURSES IS LIMITED
 INSOLENT SURVEYORS
 MANUAL METHOD OF COUNTING, WHICH IS UNRELIABLE AND

IRREVERSIBLE
 SHORT-TERM (20 MINUTE) DATA COLLECTION

CCTV FOOTAGE OR CAMERA RECORDING IS NOT AVAILABLE.
