CAUSE OF THAT CRASH. >> ONE MONTH AFTER A FAMILY OF FOUR WAS KILLED AT A BUS STOP IN SAN FRANCISCO, THE CITY IS ANNOUNCING A PLAN TO MAKE THE STREETS SAFER. THE CITY WANTS TO CHANGE UP THE MAIN ROADS IN THE WEST PORTAL NEIGHBORHOOD, DESPITE THE PUSHBACK THEY'RE GETTING FROM LOCAL BUSINESSES. AS ABC SEVEN NEWS REPORTER LUZ PENA HAS BEEN FOLLOWING THIS STORY AND IS OUT LIVE IN SAN FRANCISCO. WITH THIS NEW PROPOSAL, LUZ. >> DAN, THIS COMMUNITY IS STILL SHAKEN BY THAT TRAGEDY, AND VERY SOON SFMTA COULD BE MAKING CHANGES THAT WILL IMPACT PEDESTRIANS AS WELL AS BUSINESS OWNERS.
