Performance Evaluation of TMA in Arrival Traffic at IAH

摘要

The measure of performance evaluation of TMA is performed for the arrival traffic operations at IAH. Our evaluation of TMA performance at IAH is solely based on the actual and schedule arrival data obtained from FAA. The runway allocation assessment analysis performed in this paper shows improvement in balanced flight distribution to the runways. Also, the delay analysis consistently indicates the reduction of the arrival delay from June 2004 which coincidentally was the start month of the full capacity TMA operation. The distribution distortion index shows that, for three rush hour periods, January - June 2004 has better arrival distribution compared with the same period in 2003. The improved arrival distribution in 2004 could reduce controller work load and increase arrival traffic awareness. Also, the variance of the arrival times was much lower in the period of the full operation Post-TMA.
