Abstract

Following the success of the Victorian Activity & Travel Survey (VATS) of household travel, the Transport Research Centre (TRC) is embarking on a Freight Activity & Commercial Travel Survey (FACTS) to provide a much needed database of freight-related information for the Melbourne metropolitan area. The objective is to provide detailed, accurate and current data on freight travel and commercial activities in metropolitan Melbourne. FACTS will be an ongoing survey collecting information on travel, loading and unloading activities, the vehicle and some basic information on the driver.

The survey design requires that information on vehicle location be collected using a Geographic Positioning System (GPS) receiver, with GPS differential correction to increase accuracy to within 5m. This (GPS) tracking data will be linked to a Geographic Information System (GIS) package to allow vehicles to be geographically viewed as they move around the road network, and to enable mapping of the vehicle location trajectories to the underlying road network database. The GPS receiver will be linked to a palmtop computer housed in a portable Data Capture Unit (DCU) located within the vehicle cabin. A touch-screen on this palmtop will be used to obtain information from the driver about the loading and unloading stops.

This paper will outline the survey methodology, and will discuss some results from the pilot survey conducted in the first half of 1998.
