Is it gone now?
I couldn't say whether IDOT is still collecting survey data, but, for now, it can be found at the url below.
Sorry I'm late in my follow up on this -- that's what I get for hitting "Stop Following".
Thanks to all who took the survey! Looks like at least 20 Chainlinkers did based on this post alone. I know Active Trans and Riders for Better Transit also posted the link on their FB pages.
I suspect IDOT closed the survey because the data was skewing so far in favor of bicycling and pub trans. Wouldn't that be great? I can't see dozens of car drivers getting excited about taking an IDOT survey, so we prolly outnumbered them, or at least gave 'em a run for their money. I'd love to see those survey results.
