Research in lane-oriented Urban Road Network Model based on GIS_T

With the rapid urban development and traffic rules increasingly complex, how to establish and express in detail the real traffic network model is important. This paper based on Lane concept and geometric data with the Urban Road, carries out and build up the Urban Road Network Model related traffic attributes from Road centerline to Carriageway, until the microscopic lane, reflects the multi-level traffic attributes characteristics and topological relations of road network in Road centerline, Carriageway and lane. Finally, This paper build the road network of Ganzhou city in Jiangxi according to road data, which can meet the microscopic traffic simulation of the route guidance, traffic assignment and so on.
