We're trying to estimate agony on the NYC subway by monitoring time between trains and adding unhappy points for stations typically crowded at rush hour. Let us know if our scoring matches your feelings. (Sorry, live data available only for these numbered lines.)
Train frequency is calculated from the MTA Real-Time Data Feeds. WNYC scores the agony based on how the previous hour's real frequency compares to its scheduled frequency. Unhappy points are added during rush hours, in the rush direction, along stretches where more people enter stations than exit, according to MTA turnstile data.. That calculation subject to change with feedback. :-) Feel free to put this interactive on your own web page. Just copy and paste this html code into your site.
