This op-ed discusses the Vision Zero initiative to make Philadelphia streets safer. It notes that each year nearly 100 people are killed or critically injured in traffic accidents in Philadelphia and surrounding counties. Vision Zero originated in Sweden and aims to reduce traffic deaths and injuries through better enforcement of traffic laws and redesigning streets to encourage safer behaviors. The op-ed argues that Philadelphia should implement Vision Zero strategies like New York City has, through increased enforcement, accountability for drivers, and reengineering dangerous streets. It says a focus on these issues from the mayor and city council could help eliminate preventable traffic tragedies.
