Steve MacKay spends his time at his day job analyzing data for the Health Authority. And that skill came into play after more than 20 accidents along the residential stretch of Robie Street where he lives. He had noticed some vehicles travelling up to 90km/hr past his home located between Stairs and Columbus Streets. That's just north of where Robie branches off from where Massachusetts Avenue begins. He admits he did go through the formal process of writing emails and lodging complaints with his councillor, Lindell Smith. He and his neighbours also put out green bins to try and slow vehicles down. And after launching a petition and repeatedly posting from his Raccoon at Home Twitter account, traffic calming measures are finally coming. HRM will be installing four-way-stops and crosswalk markings in two intersections along that stretch of Robie this summer. And MacKay is sharing his lessons he's learned along the way.
