The Vision Zero Philadelphia conference Thursday began a process that should lead to the city streets being safer. One of the conference's goals is the creation of a mayor's task force by January to look at ways Philadelphia's streets might have fewer car-related crashes. The stats, reported here, are sobering. Philadelphia had about 11,000 automobile crashes a year on average from 2009 to 2013, resulting in 90 to 100 deaths a year, according to a report from the Bicycle Coalition. That same report found that in 2013, 40 percent of the Philadelphia's traffic fatalities were from autos hitting pedestrians.
