Session Detail - Roundabout Reconstruction Using Corridor Models

Session Title:		Roundabout Reconstruction Using Corridor Models
Abstract:		In this session, you'll learn how to build a Corridor to model the reconstruction required for adding a new lane to an existing roundabout. This involves rerouting an existing approach lane with new horizontal curves and blending it into the roundabout to construct a new exit lane with minimum disruption. We will achieve this with a combination of AutoCAD Civil 3D objects, carefully controlling the vertical design to adhere to design standards.
Target Audience		Road designers familiar with Civil 3D objects
Key Topics Covered		- Apply the "Fixed-Floating-Free" Civil 3D Alignment elements to practical scenarios - Take advantage of the "Transparent Commands" to highlight regions of interest on Profile Views - Establish maximum/minimum ranges to act as a guide for design profiles - Use Rehab subassemblies to extend existing, and overlay existing, lane ways - Combine all of the above into a Dynamic Corridor model for analysis
