Yesterday's horrific vehicular attack on cyclists and pedestrians along the Hudson River Greenway, and on the occupants of a school bus at the intersection of Chambers and West Streets, was the deadliest terror attack in New York City since 9/11. It was also a stark reminder of the damage that can be done to vulnerable street users, intentionally or not, by a driver of a motor vehicle.

We extend our most heartfelt condolences to the victims, their families, and their friends. And we urge city and state officials to act without delay to improve the safety of the Hudson River Greenway, and all of New York City's bike paths, sidewalks, public plazas and streets. We must commit to substantially reducing the presence of cars and trucks in the city's densely populated areas, further reducing speed limits, and building the protective infrastructure necessary to keep pedestrians and cyclists safe. We must rapidly expand the use of automated, non-biased, enforcement cameras, and implement a congestion-pricing program.

Not next year, not next month. Now.
