Airport surface gridlock analysis: A case study of Chicago O´Hare 2007

Currently, Traffic Management Initiatives (TMIs) only consider one problem at the time and ignore the effects of decisions on other components of the system, for example: - GDP, focuses on arrival flights only, creating priority for arrival flights over departures which in turn causes greater departure delays, taxi times and ultimately grid-locks. - AFP, focuses on one flow constrained area, flights from one airport get priority over another airport in close proximity causing delays. (ORD, MDW) and (LGA, PHL) are examples for such airports.
