Having previously established that Pittsburgh’s buses do bunch and a technical platform for archiving and accessing historic bus service data, I sought to extend this inquiry by quantifying aspects of frequency, timing, and location of bus bunching. The resulting project is available online at: http://bunching.github.io Dataset Vehicle locations for all buses servicing routes 61, 71, P1, and G2 were recorded once every sixty seconds throughout the month of March, 2016, resulting in a dataset of some 1.5m records of timestamped bus locations. Each location dataContinue Reading “The When and Where of Pittsburgh’s Bunched Buses”

It’s a bit messy (time constraints!) but I recently put together a simple web page that displays the average time between bus arrivals for any PAAC Route 61A/61B/61C/61D stop. It also shows the average wait time, and the excess wait times caused by variance in arrival time spacing. This website can be accessed at the following link: http://pittsburgh-bus-wait-times.appspot.com/

The human stuff is the main stuff, and the data should enrich it. ~Jonathan Harris The quote led me to Jonathan Harris’s website, which profiles his work as a digital artist. My immediate impressionContinue Reading “Human Stories vs Data”
