Bunching of bunches of buses.
Nobody wants that.
According to the creators:
Pittsburgh’s bunched buses bear the bad news of crowding (the front bus is often overfull, with subsequent buses nearly empty), excess waiting (bunching creates long waits between bus arrivals), and underutilization (crowding and unpredictable arrivals reduce public transit use). Caused by the cascading effect of variance in passenger arrivals, bunching bedevils public transit planners not just in Pittsburgh but in cities around the globe.
Does bunching follow predictable patterns? This project presents the geotemporal occurrence of bus bunching in Pittsburgh for PAAC routes 61, 71, P1 and G2 during March 2016.
