Abstract

Perishable goods are a kind of cargo that its transportation conditions are very important. This importance is Because of food hygiene and because of waste reduction. One of prerequisite for planning a cold chain transportation of perishable cargo is demand estimation. For this Propose, this paper is studying behavior of transportation of perishable goods in roads by estimating demand model. The model which is estimated for each of the provinces use panel data. The results show that for every one person increase in province's population perishable cargo transportation demand increases by 78.5 ton-kilometer, for every one million Rial increase in province's real GDP perishable cargo transportation demand increases by 18.49 ton-kilometer, for every one ton increase in province's milk production perishable cargo transportation demand increases by 91738.8 ton-kilometer, for every one thousand ton increase in province's meat production perishable cargo transportation demand decreases by 604516.5 ton-kilometer, for every one thousand ton increase in province's poultry production perishable cargo transportation demand decreases by 81006.3 ton-kilometer and finally for every one Rial increase in ton kilometer transportation real fare perishable cargo transportation demand decreases by  309386.3 ton-kilometer.
