c4302 transportation planning (o-d study)
TRANSCRIPT
b. Data Collection A complete database in transportation
planning is very important because all data can become a base in understanding the interaction between the transportation movement along the study area
Data collection is very important in transportation planning because the occurrence of error and mistake in this stage can cause incorrect model determination. In addition, a larger error may occur when making prediction for the future

5 important component in a database:1. Current data related to the
transportation system. Such as roadways, highways, public transport services, traffic management, and etc.
2. Current usage of public transport, such as the traffic flow on the main road, bus services, etc

Data AnalyzeUsing CODING and PUNCHING methodData will be coded in one serial number pre-
determine form. The information will be coded and punched into
one paper tape for separating the data using mechanically and processing method.
Data will separated into origin and destination only, and the other will code into travel mode and etc.
Later after coding process has finish then it will be transferred into punch card or paper tape by an expertise, and this will be used as input in the computer
