Junction road roles
Junctions between main and side roads, with give-way stop and yield lines.
MODULE 04 / 12 · JUNCTIONS & ROUNDABOUTS
Every junction,
checked as you draw.
Lay out T-junctions, crossroads, roundabouts, cul-de-sacs and knuckles inside the corridor model. Tapers, returns, islands, turning, lay-bys and stagger are reviewed against built-in South African and AASHTO 2018 guidance rule sets that you can adapt to each road authority.

Single and three-centred kerb-return curves.
Crown and crossfall checks
Check held-crown crossfall connections at junctions.
Cul-de-sac bulbs
Design offset circular cul-de-sac bulbs.
Roundabout footprints
Save roundabout footprints and compare them with other junction layouts.
Knuckle checks
Check knuckle geometry for steady turning.
Parking and bus bays
Saved parking and bus bays tied to a road's kerb offset.
Splitter islands
Rectangular median and splitter islands at junctions.
Footway ramp calculator
Calculate footway ramp and landing geometry from your inputs.
Road-end tie levels

Junction overlap diagnostics
Detect overlapping footprints between junction elements.
Editable guidance rule sets
Built-in South African and AASHTO 2018 junction guidance sets, each value cited and editable for your road authority.
HAND IT TO YOUR AGENT
Three briefs to start with.
BRIEF 01
“Add a T-junction for the access road at 0+260 and check the returns for a 60 km/h main road.”
BRIEF 02
“Compare the roundabout and crossroads footprints at the northern intersection.”
BRIEF 03
“Which junctions break the stagger rule in the South African guidance set?”
