Because of the high costs, in terms of crew time, maintenance and jet fuel (over $150 million per year) incurred because of delays caused by congestion of airport systems and because, beyond a certain point, a small increase in demand (i.e., percentage of capacity) results in a substantial increase in delay, a number of simulation analyses were made to determine ways of increasing airfield capacity (and hence reduce delay) at O'Hare International Airport. Results indicate that capacity can be improved substantially by changing the runway configurations. Another source of conjection is the separations required to avoid the turbulence of wake vortexes. The use of wake vortex detection systems can alleviate delay by permitting smaller paths which would increase capacity by 15 percent and reduce delays by 50 percent. Other recommendations include instituting and enforcing quotas during peak periods and developing an effective and equitable system of flow control when disruptions are anticipated, including improved predictions of capacity for the coming period.
