burst traffic vs constant traffic, where burst can be defined as commute times. you can see the affect in downtown Portland, where car traffic was mostly concentrated to burst hours with the rest of traffic being a relative trickle of vehicles that weren't delivery or transit vehicles. now, it's a constant stream of lyft/uber labeled cars at all hours, in addition the the burst hours. anecdotally, no passengers most of the time (around 70%), seeming to be between fares.
