A GIS-based traffic forecasts for transport planning of Guangdong province

This paper describes a GIS-based traffic forecasts for transport planning of Guangdong Province in assessing the effects of road traffic plans. This work utilizes capabilities of GIS to integrate the multi-data from a transport planning activity to predict traffic volume impacts of different road traffic scenarios through twice development based on TransCAD software. It enables planners to test transport related road traffic changes at the same time as they are testing the traffic carrying efficiencies of complex and large-scale network plans. The suitability of this type of traffic forecasts for planning purposes is illustrated by using a case study.
