What we have needs to change
What we have is alright

Improving SAFETY while crossing the road
Safe left turns
Improving SAFETY while crossing the road
Speed reduced by 60%
Improving SAFETY while crossing the road
A space to wait while crossingImproved and constrained turning – notice the police standing in the refuge
Junction Re-design
Existing Situation – No clear space for cyclists and pedestrians which is blocked by parked vehicles
Junction Re-design
New Situation – Space created for cyclists and pedestrians by aligning parking away from edge.

IMPACT
Do you feel street safe? (pedestrians)
IMPACT
THE IMPACT
Geometric Design of Junction
Pedestrian safety at the junction. High IncreaseSafety for cyclists at the junction. Little IncreaseHigh turning speeds. Reduced by 60%High incidence of wrong lane driving (opposite currents). Reduced by 90%Large wait time at junctions. Decrease by 35%Managing traffic. Easy
