We have big problems in the Bay Area, and they arguably impact every resident.  Traffic.  Congestion.  Backups on Bay Area bridges.  Public transit that doesn't meet the needs of all commuters.  Dr. Karen Philbrick, Executive Director of the Mineta Transportation Institute at San Jose State University, speaks with KCBS Radio's Stan Bunger and Holly Quan about the problems and efforts to identify solutions.  And, that conversation absolutely includes talk about ride-hailing services like Uber and Lyft--the benefits AND additional problems created by ride-hailing services.  Transportation, Dr. Philbrick says, has to be a discussion about "personal mobility"--and that even includes skateboards, bikes--tools that help people reach transit hubs.
