3 years ago I changed the date from 1/21/19 to 2/6/19 because a different metra schedule started on 2/4/19. I also changed the available modes from 'Walk, Transit, Subway, Rail, Bus' to 'Walk, Transit'. Looks like the later change has corrected things. I will comment an updated transit travel time heatmap whenever I complete it. Looking at the travel times between a select few census tracts showed me that many of the travel times reduced by about 30 minutes when I made the "available modes" change. I am guessing that including all of the modes made it assume that only the last one should be used, so the program was assuming that walking and taking a bus were the only available modes.
Greg and I looked over a few visualizations of the OTP transit travel times. There was a few census tracts with missing travel times, which could make sense for the few that we looked around the outskirts of the city limits. There was an area next to the Midway Airport that did not look right and the travel time to O'Hare Airport to downtown Chicago was about 1 hour and 45 minutes long. Google estimates the trip from O-Hare to downtown to be around 45 minutes. I need to dig into the OTP script to understand why it is calculating such high travel times.
