The Development and Implementation of a Comprehensive Transportation GIS Network
Tina RobertsAdiele Nwankwo
Geographic information systems technology is rapidly being introduced into various facets of transportation planning. In many cases, GIS is implemented to address a specific need, which has left agencies with fragmented GIS networks and tools. SEMCOG in cooperation with State and local agencies, is addressing this potential problem by working together to create a comprehensive transportation GIS network for planning applications in the region. The objective of this work is to establish a common base containing essential attributes to be utilized by both the State and local agencies for the development of applications including, but not limited to, transportation planning. This paper presents the initial development of the comprehensive transportation GIS network including the lessons learned in conflating/merging multiple GIS and non-GIS files into a composite regional transportation base, and the challenges of working with multiple agencies that have varied goals and objectives, products, and time frames. Examples of transportation planning applications implemented to date using the Esri ArcInfo software, include the network development/update and display of the TRANPLAN's travel demand forecast results, traffic safety analyses, and the use of GIS in intelligent transportation systems operations in transit and general planning applications.
