Abstract
Although parking for loading and unloading should be performed outside streets in principle, actually it is difficult to manage parking demand only in off-street loading and unloading facilities, which has become one of the causes of traffic congestion. In order to manage on-street parking for loading and unloading, it is necessary to analyze the characteristics of delivery and collective trucks behavior during the parking duration. This research analyzes the characteristics of delivery and collective trucks behavior, which can be regarded as a chain that consists of the activities of loading and unloading and the trips between a parking location and the visiting site. Addition to this, this research explains how to determine the catchment area of a loading zone which is a parking facility for delivery and collective trucks.
