This reconstruction shows the conversion of a large car-oriented intersection into a compact, well-delineated, and safer node.
Remove pedestrian overpasses and replace them with at-grade crossings. This reduces crossing time and distance, increases sidewalk space, and makes the pedestrian crossing accessible for all users.
Reduce turning radii and reclaim space at the corners to safely accommodate high pedestrian volumes. This creates additional space for transit stops and street vendors.
Install pedestrian refuge islands to reduce crossing distance and provide a protected waiting space.
Reduce the lane width and extend the central median as a simple, cost-effective measure to improve safety.
Extend ground markings for cycle lanes through the conflict zone of the intersection, matching the width and positioning of the leading cycle lanes.
Prioritize mass transit to increase the capacity on busy streets. Convert a travel lane in each direction of the two-way street, and one lane of the one-way street, into transit-only lane.
On the one-way street, remove one travel lane to add a parking-protected, two-way cycle track.
On the two-way street, add a raised cycle track on each side of the street, ramping lanes up to meet sidewalk level when they are adjacent to transit stops. Ensure a change in markings to indicate these potential areas of conflict between cyclists and transit riders.
Define travel lanes through markings and reduce their width in order to reduce vehicular speed.
Addis Ababa, Ethiopia. An interim transformation showcasing the principles such as tightening the corner radii, adding appropriate intersection markings and reducing crossing distances.
