Abstract
This study sets two research interests based on existing studies which have estimated high values of time (VOT) of cargoes. The first interest is the cause of such high VOT of cargoes. The second interest is that high VOT of cargoes can increase the buffer capacity of freight transport. Under these research interests, this study theoretically analyzes the relation between lead time and profit of consignee, and the relation between VOT of cargoes and buffer capacity of truck transport. The analysis finds the following theoretical implications. Other things being equal, VOT of cargoes can be higher when the travel distance is shorter or the consignee is small. Shortening travel time of trucks can reduce the buffer capacity of trucks, and thus can save the cost of trucking industry.
