Abstract: This paper studies the combined transports of vehicle logistics.In order to save the cost,according to the current feature of independent transports model of vehicle logistics,this paper puts forward the conception of combined transports for the franchisers in the same region,and proves that the merge-factor is the main factor affecting the combined transports.By further analysis,when competitive relation exists among the franchisers,the related coefficient corresponds to the cost saving.

Key words: vehicle logistics, cost saving, combined transport, merge-factor
