  32. 32. VARIATION OF VOLUME FINDINGS:  TRAFFIC FLOW IS UPRISING GOING TOWARDS THE MAIN CENTERS.  MORNING PEAK 
  33. 33. VEHICLE COMPOSITION
  34. 34. VEHICLE COMPOSITION FINDINGS: PREDOMINANT VEHICLE TYPE: PERSONALIZED VEHICLE NEGLIGIBLE AMOUNT OF PUBLIC TRANSPORT  RELATIVELY HIGH PERCENTAGE OF NON-MOTORIZED VEHICLE
  35. 35. PCU & LOS  PCU- IT IS PASSENGER CAR UNIT.  LOS- LEVEL OF SERVICE IS EXPRESSED AS OPERATIONAL CONDITION OF TRAFFIC STREAM AND DETERMINE EFFECTIVENESS OF TRANSPORT INFRASTRUCTURE.

  37. 37. LEVEL OF SERVICE LOS SERVICE FLOW RATE (PCU/HR) A 600 B 700 C 900 D 1200 E 1400 F >1400 According to this classification of Level of Service, estimated Level of Service during survey period was ‘C’.
  38. 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. 
  39. 39. DIRECTIONAL DISTRIBUTION DIRECTION FROM PANTHAPATH TO RUSSELL SQUARE FROM RUSSELL SQUARE TO PANTHAPATH TIME PCU/HR 9:00AM10:00AM 10:00AM11:00AM 11:00AM12:00AM 9:00AM10:00AM 10:00AM11:00AM 859.5 10:00AM12:00PM AVG.

  40. 40. DIRECTIONAL DISTRIBUTION 45% 55% From Panthapath To Russell From Russell Square To Panthapath
  41. 41. DIRECTIONAL DISTRIBUTION FINDINGS:  DIRECTIONAL DISTRIBUTION OF PANPTHAPATH TO RUSSELL SQUARE IS 55% AND RUSSELL SQUARE TO PANTHAPATH IS 45%  THE DIRECTIONAL DISTRIBUTION IS MORE OVER UNIFORM.  SOME PART OF THE ROAD TIDAL FLOW IS SEEN.
  42. 42. FLOW FLUCTUATION 1200 1000 PCU/Hr 800 600 400 200 0 From panthopath to russell square From russell square to panthopath Avg 09.00am10.00am 10.00am11.00am 11.00am12.00pm 859.5 898.8 1125.6 726.6 822.9 836.7 793.1 860.9 981.2
  43. 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. 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. 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. 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. 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. 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.
