Traffic infrastructure design and geo-information systems, a case of interoperability

Using computer programs, Intelligent Road Design attempts to establish a connection between two points through an economical path. Born around 30 years ago, Computer Aided Design (CAD) can provide rapid evaluation of alternative alignments, optimization techniques for road planners and powerful search tools for a large number of alternative alignments. Geospatial Information System (GIS) with its spatio-temporal analysis tools is an extremely helpful solution in the very early steps of alignment planning, especially for long railway projects. Therefore Road and Railway (Rd & R1) Design is a suitable area of help for GIS design applications, as such projects start with topographic maps and map analysis methods. When used together effectively, CAD and GIS fulfill the prerequisites for streamlining decision making and reducing inefficiencies in the design and execution of critical operations.
