To this end, people think of united transportation of railways and highways to give full play to respective advantages of the highway transportation and the railway transportation. Specifically, highway transportation vehicles (mostly semitrailers) transport cargoes to transit sites, then the cargoes are carried onto railway transportation vehicles, the cargoes are carried onto the highway transportation vehicles after arriving at the vicinity of destinations, and finally the highway transportation vehicles transport the cargoes to the destinations. Although this transportation mode can give full play to their respective advantages of the highway transportation and the railway transportation, the carrying of the cargoes is very troublesome, so the efficiency of logistics transportation is seriously reduced.
