WORK PROCESS DOCUMENT

1. Necessary preparations such as an accurate watch is performed

and the correct time was set, sufficient pens, field data forms and
clipboards, mechanical hand tally counters that are in good
condition, safety vests and others
2. Enumerators were arrived 30 minutes earlier at the site in order to

familiarize with location, distribute the equipment, fill in the general
information of the tally forms that comprised of sheet number,
station ID, enumerator’s name, date, weather condition and time
to start or finish.

3. Enumerators have to do field measurements in order to define
existing geometric dimension for the intersection under study.
4. The layout of the intersection was sketched and dimensioned.

5. The current traffic movements (through, left turn, and right turn)
were identified and begun at the planned time.vi. Proper
observer’s position was selected so that they can see clearly, safely

and easily count the traffic.
6. The counting is done at each lane of each intersection approach
for volume conditions.
7. The data is checked before leaving the field.
