Key factors influencing urban agglomeration highway transport network system are sought out by using systematic structure model analysis method. Three hierarchies of urban agglomeration highway transport network are abstracted such as metropolitan district, inter city and external highway transport. Four kinds of structure morphology such as network of ringy and radial road surrounding one central city, decentralized network with multiple central cities, zonal and stretchy network, and combined network are studied out.
