Manual Method: DirectUSING HAND TALLY AND MANUAL COUNTERSIMMEDIATELY USED BUT

NOT PRACTICABLE FOR LONG DURATIONERROR PRONE SPECIALLY

WHEN HIGH VOLUME

FIG: ELECTRICAL COUNTING BOARD


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’.

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.

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.

FLOW FLUCTUATION

INTRODUCED OF PUBLIC TRANSPORT IN A LARGE SCALE.LIMITED USE OF PERSONALIZED VEHICLES.NON-MOTORIZED VEHICLES USED SHOULD BE RESTRICTED.

RECOMMENDATIONS FOR VEHICLE COMPOSITION

FOR BETTER LEVEL OF SERVICE RESTRICTIVE AND CONTROLLING MEASURES IS NEEDED

CROSS-SECTIONS ELEMENTS, PARKING AREA, SHOULDER ETC SHOULD BE TAKEN IN PROPER MEASURES.

RECOMMENDATIONS FOR LEVEL OF SERVICE

DIRECTIONAL DISTRIBUTION VALUE IS SHOULD NOT GOING TO

DEVIATED FROM DESIGN VALUETHE VALUE SHOULD BE IN 55% IN EVENING THE DATA IS GOING IS REVERSED.

RECOMMENDATIONS FOR DIRECTIONAL DISTRIBUTION

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.

RECOMMENDATIONS FOR FLOW FLUCTUATION

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.
