| Abstract | A number of counts and roadside origin-destination surveys of commercial vehicles were carried out to provide data for future transportation planning and design, especially for the proposed truck terminals
in the vicinity of Bangkok. In these counts and interviews for each principal route to Bangkok, commercial vehicles were counted and interviewed
separately for each direction with the commercial traffic sub-divided by wheel arrangement and with their body types.
Data were obtained on the origin, destination, commodity carried, weight of the commodity and places of pickup and delivery of particular types of commercial vehicles at four sites. The information was collected
by asking questions of the truck drivers when they were stopped in the weighing station lay-by on request of the Highway Police.
The data were analyzed after coding in the computer and results have been produced in terms of daily total truck volumes, commodities carried by truck type, number of trips between zones, hourly flow variations by vehicle type, and trip length. The findings of this survey revealed that the daily volumes of trucks in each direction on the principal routes are in the range of 4000 to 6000
on four-lane highways and 2000 to 3000 on two-lane highways. There is a significant variation in the hourly flow of trucks the peak hours being from 10:00 hrs to 15.00 hrs. There is no significant daily variation in the flow. The nature of pickup and delivery of commodies is single
type. The principal origins and destinations of commodities in Bangkok are Phasi Charoen-Bang Khun Thian, Yaowarat, Thonburi, Phra Pa Daeng;
those outside of Bangkok are Saraburi, Chonburi, Ratchaburi, and Nakhon Pathom. Most of the trucks are six and ten-wheelers. The inbound commodities are mostly construction materials, food grains, timber; outbound
commodities are manufactured products, cold drinks and general cargo. Because 76% of all trips are shorter than 150 km in length and only 0.15% of total trips have multiple .origins or destinations, truck terminal considerations need further investigation. The 0-D survey was found fruitful in Thailand for getting information. However, recommendations for further studies were made to find some more useful statistical information. |
