Transcript of Modeling Bus Bunching
What is bus bunching?
http://interactive.wbez.org/curiouscity/bus-bunching/
• Space between buses shrinks as the front bus is delayed
• As the front bus gets more crowded, it slows even more
• Emptier following bus gets faster• Resulting accumulation of delays
• Where, when in the course of a day and why does bus bunching occur?
• Can bus bunching be predicted?
line80[, diff:= ist_an_von-shift(ist_an_von), by=.(halt_kurz_von1, datum_von)]
• created a new variable that calculated the time difference between busesarriving at each stop by day
• Defined bus bunching as <180 seconds
