TRAFFIC ENGINEERING

PREPARED BY: B.V.KACHHOT

Definition: It is the phase of transportation engineering that deals with the planning, geometric design and traffic operations of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation

O & D SURVEY

THE ORIGIN AND DESTINATION STUDY IS CARRIED OUT MAINLY TO KNOW THE ORIGIN AND DESTINATION OF VARIOUS VEHICALS .

IN THIS STUDY THE DATA COLLECTED ARE, NUMBER OF VEHICLES, THEIR ORIGIN AND DESTINATION NUMBER OF PASSENGERS IN EACH VEHICLE,ROUTE ETC.

USE FOR O & D SURVEY

TO JUDGE THE ADEQUACY OF EXICTING ROUTES

TO ESTABLISH PREFERENTIAL ROUTES FOR VARIOUS CATEGORIES OF VEHICLES

TO LOCATION OF NEW PROPOSED ROADSTO LOCATION OF PARKING PALACESTO LOCATE EXPRESSWAYTO REGULATE MOVEMENT OF HEAVY

VEHICLESTO LOCATE NEW BRIDGE AS PER TRAFFIC

ROAD SIDE INTERVIEW SURVEY

IN THIS METHOD INTERVIEW STATIONS ARE PREVIOUSLY DECISED ON THE ROADWAY.

THE VEHICLES ARE STOPPED AT THE INTERVIEW STATIONS BY A GROUP OF PERSONS AND THE ANSWERS TO PRESCRIBED QUESTIONNAIRE ARE COLLECETED ON THE SPOT.

INFORMATION COLLECTED

ROAD SIDE INTERVIEW SURVEY

ADVANTAGES & DISADVANTAGES

ADVANTAGES :DATA IS COLLECTED QUICKLY IN SHORT

DURATIONFIELD ORGANIZATION IS SIMPLE

DISADVANTAGES:THE VEHICLES ARE STOPPED FOR

INTERVIEW AND THERE IS DELAY TO THE VEHICULAR MOVEMENT

HOME-INTERVIEW SURVEY

IN THIS METHOD RANDOM SAMPLE OF 0.5 TO 10% OF THE POPULATION IS SELECTED AND THE RESIDENCE ARE VISITED BY THE TRAINED PERSON WHO COLLECT THE TRAVEL DATA FROM EACH MEMBOR OF THE HOUSEHOLD.

DETAILD INFORMATION REGARDIND THE TRIPS MADE BY THE MEMBERS IS OBTAINED ON THE SPOT.

THE DATA COLLECTED MAY BE USEFUL EITHER FOR PLANNING THE ROAD NETWORK AND OTHER ROADWAY FACILITIES.

ADVANTAGES & DISADVANTAGES

ADVANTAGES:THE PROBLEM OF STOPPING OF VEHICLES

AND CONSEQUENT DIFFICULTIES ARE AVOIDED

THE PRESENT TRAVEL NEEDS ARE CLEARLY KNOWN AND THE ANALYSIS IS ALSO SIMPLE.

ADDITIONAL DATA INCLUDING SOCIO-ECONOMIC AND OTHER DETAILS MAY BE COLLECTED SO AS TO BE USEFUL FOR FORECASTING TRAFFIC AND TRANSPORTATION GROWTH.

TELEPHONE SURVEY

THIS METHOD INTERVIEW ARE CONDUCT WITH COMPUTER ASSISTED TELEPHONE INTERVIEW TECHNOLOGY.

A COMPLETE CATI SYSTEM MIGHT INCLUD AUTOMATIC DAILING OF NEXT HOUSEHOLD TO THE INTERVIEWER TO ASK THE NEST QUESTION AUTOMATIC SKIPPING AND BRANCHING WITHIN THE LIST OF QUESTIONS DEPENDING ON THE ANSER TO THE PREVIOUS QUESTION ,IMMEDIATE LOGIC CHECKS ON ANSWER PROVIDED.

TELEPHONE SURVEY

ADVANTAGES:SAVING THE TIME DISADVANTAGES:INFORMATION RESPONCE NOT GOOD

TELEPHONE SURVEY

TAXI SURVEY

LARGE URBAN AREAS USUALLY HAVE A SIZEABLE AMOUNT OF TRAVEL BY TAXIS.

IN SUCH CASES, A SEPARATE TAXI SURVEY IS NECESSARY .

THE SURVEY CONSISTS OF ISSUING QUESTIONNAIRES OR LOG SHEETS TO THE TAXI DRIVERS AND REQUESTING THEM TO COMPLETE THE SAME.

TAXI SURVEY

POST CARD

IN THIS METHOD REPLY-PAID QUESTIONNAIRES ARE HANDED OVER TO EACH OF THE DRIVERS AT THE SURVEY POINTS AND REQUISTING THEM TO COMPLETE THE INFORMATION AND RETURN BY POST.

ADVANTAGES:THIS METHOD ARE SIMPLER AND

CHEAPER THAN MANY OTHERS.

DISADVANTAGES:RESPONSE MAY NOT A GOOD

POST CARD

REGISTRATION NUMBER PLATE SURVEY

REGISTRATION NUMBER PLATE SURVEY CONSISTS OF NOTING THE REGISTRATION NUMBER OF VEHICLES ENTERING OR LEAVING AN AREA AT SURVEY POINTS LOCATED ON THE CORDON LINE.

BY MATCHING THE REGISTRATION NUMBER OF THE VEHICLES AT THE POINT OF ENTRY AND EXITFROM THE AREA , ONE IS ENABLED TO IDENTIFY TWO POINTS ON THE PATHS OF THE VEHICLES.

ADVANTAGES:WORK DOES NOT INTERFERE WITH THE

TRAFFIC IN ANY WAY.

DISADVANTAGES:LARGE NUMBER OF OBSERVERS ARE

NEEDED ANALYSIS OF THE RESULTS CAN BE

COMPLICATED.PREPARED BY: B.V.KACHHOT

TAG SURVEY

IN THIS METHOD AT EACH POINT WHERE THE ROADS CROSS THE CORDON LINE, VEHICLES ARE STOPPED AND A TAG IS AFFIXED ,USUALLY UNDER A WIND SCREEN WIPER.

THE TAGS FOR DIFFERENT SURVEYS STATIONS HAVE DIFFERENT SHAPES/COLOUR TO IDENTIFY THE SURVEY STATION.

THE VEEHICLES ARE STOPPED AGAIN AT THE EXIT POINTS WHERE THE TAGS ARE REMOVED.

THE TIME OF ENTERING AND LEAVING THE AREA MAY BE MARKED ON THE TAGS IN ORDER TO ENABLE THE JOURNEY TIME TO BE DETERMINED

ADVANTAGES:THIS METHOD IS SIMPLE AND ERROR ARE

NOT VERY LARGE.

DISADVANTAGES:IT IS NOT POSSIBLE TO HANDLE ALL THE

VEHICLES, SAMPLING MAY BE RESTORED TO DONE.

TAG SURVEY

PUBLIC TRANSPORT SURVEYS

IN THIS METHOD INTERVIWER MAY ENTER THE VEHICLE AND CARRY OUT THE INTERVIEWS WHEN THE VEHICLES IS IN MOTION.

POST-CARD QUESTIONNAIRES ELIMINATE DELAYS, BUT ARE LIKELY TO EVOKE POOR RESPONSE OR CONTAIN AN ELEMENT OR BIAS.

THESE QUESTIONNAIRES MAY ALSO BE COLLECTED AT THE STATIONS INSIDE THE SURVEY AREA.

PUBLIC TRANSPORT SURVEYS

COMMERCIAL VEHICAL SURVEYS

COMMERCIAL VEHICLE SURVEYS ARE CONDUCTED TO OBTAIN INFORMATION ON JOURNEYS MADE BY ALL COMMERCIAL VEHICLES BASED WITHIN THE STUDY AREA.

THE ADDRESSES OF THE VEHICLES OPERATORS ARE OBTAINED AND THEY ARE CONTACTED .

FORM ARE ISSUED TO DRIVERS WITH A REQUEST THAT THEY RECORD PARTICULARS OF ALL THE TRIPS THEY WOULD MAKE.

COMMERCIAL VEHICAL SURVEYS

TRIP GENERATION ANALYSIS

PURPOSE TO DEVELOP EQUATIONS OI , DJ

(THE TRIP ENDS OF A PARTICULAR TRIP TYPE GENERATED BY EACH ZONE BASED ON LAND USE)

TRIP DISTRIBUTION ANALYSIS

PURPOSE TO ESTIMATE THE NOS. OF

TRIP BETWEEN EACH PAIR OF ZONES ( VIJ)

MODAL SPLIT ANALYSIS

Purpose TO DETERMINE THE NOS. OF TRIP

MADE BY EACH MODE OF TRAVEL (VMIJ)

TWO TYPES OF MODAL ANALYSIS1) PRE-DISTRIBUTION MODAL SPLIT

ANALYSIS2) POST-DISTRIBUTION MODAL SPLIT

ANALYSIS

PRE-DISTRIBUTION MODAL SPLIT ANALYSIS

BASED ON SOCIO-ECONOMIC CHARACTERISTICS - INCOME

- AUTO OWNERSHIP

- AGE - SEX

POST-DISTRIBUTION MODAL SPLIT ANALYSIS
