摘要：This paper presents a study on road network data model and its application in the vehicle navigation. Traffic network has many characteristic attributes, such as lane, cloverleaf junction and turn restrictions, which distinguish road network from general category of "directed graphs". The characteristic attributes are significant to many operations in the vehicle navigation system. However, traditional Geographical Information System (GIS) only describes the general network topology relationship, which can't satisfy the applied requirements in vehicle navigation system. So a road network data model is proposed in this paper, based on analysis of the characteristic attributes of traffic network
