I stumbled upon this presentation to local city leadership by the police department (https://youtu.be/BJNCCAJUEgM?t=9m36s https://youtu.be/BJNCCAJUEgM?t=9m36s).

I stumbled upon this presentation to local city leadership by the police department (https://youtu.be/BJNCCAJUEgM?t=9m36s https://youtu.be/BJNCCAJUEgM?t=9m36s).

There are likely many variables at play so its hard to say what truly helps prevent accidents...
