The City's Capital Improvement Program (CIP) project: Pomona Multi-Neighborhood Pedestrian and Bicycle Improvements, Project No. 428-67930, received a nearly $10M Active Transportation Program Cycle 4 (ATP C4) grant to help fund these roundabouts & other improvements throughout the City.

Roundabouts provide traffic calming as well as traffic control at intersections of streets, and typically without stop signs or traffic signals. There are many less traffic conflict points in roundabouts compared to traditional intersections, and accidents in roundabouts are usually less severe, due to the elimination of potential head-on and broadside collisions. One-way traffic in roundabouts also keeps traffic keep moving, with the exceptions of yielding to pedestrians and other vehicles near entry and exit. All these benefits make roundabouts a great way to allow multi-modal (vehicular, pedestrian, and bicycle) traffic function efficiently.

When approaching a roundabout, vehicular drivers need to slow down and be alert; however, vehicles typically only need to yield if there is a pedestrian crossing or if there is approaching vehicular or bicycle traffic already in the roundabout. If there are no pedestrians crossing and there is no other approaching vehicular or bicycle traffic already in the roundabout, then the incoming traffic may proceed through the roundabout at reduced speed. Always look left before entering a roundabout. Traffic enters and exits a roundabout by turning to the right. Traffic islands, signage, and the arrangement roundabout assist drivers through the roundabout proceeding in a counter-clockwise pattern (if viewed from above).
