CMU data science grad student Mark Egge takes on Port Authority bus bunching, charting and heatmapping one day of 61, 71, P1, and G2 buses. Egge’s analysis finds that, “contrary to what one might expect, … location is more deterministic of bunching than time of day,” and he suggests that Bus Rapid Transit (BRT) could alleviate the bunchiest of bunches, which are especially present Downtown and in Oakland and Squirrel Hill.
