A method that integrates geographic information systems(GIS) with improved particles swarm optimization(PSO) for simultaneously optimizing three-dimensional highway alignments is presented in this article. With improved PSO introduced, the complex nonlinear alignments optimization problem becomes very simple to carry out. A GIS system —ArcGIS and its object-oriented data model — Geodatabase are exploited to store relevant geographic information and highway alignment elements. An example study shows that the proposed optimization gives more efficient results than the existing methods and also improves quality of solutions.
