1: Where are today’s O’Hare passengers starting and ending their trips? The 1988 CTA study is useful, but it’s old, and CTA has never updated it. Curiously, the Chicago Department of Aviation has no numbers, and neither does the Chicago Department of Transportation or the Chicago Metropolitan Agency for Planning (CMAP), the official land-use and transportation planning agency for the entire six-county region. It doesn’t speak well for our process that the lead actor in the O’Hare drama is promoting an expensive rail link without having first gathered a reliable set of origin/destination figures. Mayor, get those numbers quick.
