3D Model for Highway Alignment

Abstract

Highway planning is often complex and time consuming because of the multifaceted nature of highway design. Transportation design and analysis has been conducted mostly in 2D and reported as time consuming, and error-prone manual drafting updates. When planning for a new highway alignment, the general practice is to identify multiple alignment options and determine the best option based on multiple factors. This research intends to build a 3D object based intelligent design model of the roadway in which elements of the design are related to each other dynamically. In order to test the feasibility of the proposed approach, a prototype object based 3D model was developed and tested on a highway project in Vadakkencherry.
