Air Traffic Management and Optimization

In this paper, we proposed an improved transportation network efficiency (TNE) measurement method, which is called passenger- and speed-weighted efficiency (PSWE). The new method is used to measure both origin-destination-level (OD-level) transportation efficiency and citywide transportation efficiency by integrating with the excess commuting (EC) framework. To show the feasibility of the proposed measurement method, we chose New York City (NYC) as the study area and employed open taxi data. By calculating the efficiency value of the OD-level, we discovered that the average distance of highly efficient taxi trips is much longer than that of inefficient trips. Then, the OD-level efficiency value is applied to the EC framework by replacing the conventional cost unit (time or distance) with the proposed efficiency impedance (Eimp). The maps of minimized OD flows indicate that taxi trips within Manhattan and to the two airports (LGA and JFK) should be particularly considered if citywide efficiency is expected to be improved.
