Highway Alignment Designer Skill

Purpose

The Highway Alignment Designer Skill designs horizontal and vertical highway alignments including curves, superelevation, and sight distance per AASHTO Green Book standards.

Capabilities

Horizontal curve design (simple, compound, reverse, spiral)
Vertical curve design (crest, sag)
Superelevation calculation
Sight distance analysis
Cross-section template generation
AASHTO Green Book compliance checking
Design exception documentation
Corridor modeling support

Usage Guidelines

When to Use

Designing new roadways
Evaluating existing alignments
Checking sight distances
Developing superelevation

Prerequisites

Design speed established
Terrain classification known
Design criteria selected
