|
The purpose of this study is to assist TxDOT engineers in the field of traffic control planning . This is to be done via the creation of a Geographic Information System (GIS ) based tool . By bringing together information about TxDOT’s on -system roadways’ geographical locations , traffic demands , and capacities , one aggregate database has been established . Using the tools of GIS , Microsoft Excel , Microsoft Access , and VBA programming , a static clickable interface has been constructed . It enables users to access properties for any selected roadway link they desire . Expansion of the product to ArcIMS is ongoing to allow easy access for end users via the internet . |
