A Powerful GIS for Transportation

TransCAD is a state-of-the-art GIS that you can use to create and customize maps, build and maintain geographic data sets, and perform many different types of spatial analysis. TransCAD includes sophisticated GIS features such as polygon overlay, buffering, and geocoding, and has an open system architecture that supports data sharing on local- and wide-area networks.

TransCAD is the only software package that fully integrates GIS with demand modeling and logistics functionality. This makes it possible for models to be much more accurate and efficient. For example, network distances and travel times are based on the actual shape of the road network and a correct representation of highway interchanges. Also, with networks, you can specify complex road attributes such as truck exclusions, delays at intersections, one-way streets, and construction zones. Further, data preparation is greatly facilitated and the database and visualization capabilities catch errors before they cause problems.

In TransCAD, different modeling equations can easily be derived and applied for different geographic subareas. Similarly, TransCAD brings new and much-needed capabilities for measuring geographic accessibility. The GIS approach also provides a graphical solution that is easily understood. Users can convey highly technical information to the non-practitioner in a very straightforward and understandable manner.

TransCAD extends the traditional GIS data model to include transportation data objects such as transportation networks, matrices, routes systems, and linear-referenced data. These extensions make TransCAD the best data management and analysis tool for working with transportation data. You can use the GIS functions to prepare, visualize, analyze, and present your work, and use the application modules to solve routing, logistics, and other transportation problems with greater ease and efficiency than with any other product. Networks and matrices can be of virtually unlimited size.
