GIS Based Traffic Impact Analysis Of Logistics Park

Logistics park is developed very rapidly for the latest few years, planning and constructing logistics park scientifically is a question for discussion recently. A primary discussion on traffic impact analysis (TIA) of logistics park is given, according to the impact of logistics system construction to urban traffic.Firstly, the background of TIA and logistics park is introduced. Secondly, a logistics-traffic volume conversion model is established, based on the models that descript the characteristics of logistics , such as Freight transportation models, Weight/Value models, Freight/time models, Freight distribution models, Vehicle models and network models, esc. This logistics-traffic volume conversion model is used to convert logistics characteristics to traffic characteristics.A TIA framework based on GIS is put forward, data collection and analysis, database design, system function design are explained in detail. According to a TrandCAD application example, the key questions of TIA of logistics park are discussed, included TIA study area, site traffic forecast, non-site traffic forecast, traffic distribution forecast, esc. A TIA evaluate model based on matter element model is introduced. Some TIA improvement methods and strategies are given, included traffic organization design, intersection and road redesign, parking place planning, esc. At last, a prospect of the development of logistics park planning and TIA technology is given.
