I suspect she was talking specifically about the Kennedy where the reversibles are. I've read at least a couple articles stating that IDOT should flip them more frequently. IIRC, there was something about the "traditional" commute being more compressed (ie stricter hours on downtown jobs), where the "reverse" is more spread out. eg, in the morning, inbound does still make sense during the heaviest time from say 7 to 9, but it should flip to outbound by 9 or something like that (I'm too lazy to dig up the article right now, so those times are almost certainly off). Might have also been outbound before 7 as well.

I think there was something about stodginess on IDOT's part as well. They have the technology to make the switch remotely, including full camera coverage to ensure the lanes have cleared, but they still choose to send a truck down the lanes well after closure to "make sure it's clear". That lengthens the time it takes to switchover, especially when I've seen the IDOT truck making that sweep and he's doing it at like 20-25.
