ACRP Report Released on Defining and Measuring Aircraft Delay and Airport Capacity Thresholds

ACRP104coverLast week, the Transportation Research Board’s Airport Cooperative Research Program (ACRP) released Report 104: Defining and Measuring Aircraft Delay and Airport Capacity Thresholds. The ACRP report offers guidance to help airports understand, select, calculate, and report measures of delay and capacity. The report describes common metrics, identifies data sources, recommends metrics based on an airport’s needs, and suggests ways to potentially improve metrics.

Guidance and recommendations are provided regarding the relevance of particular delay and capacity measures by airport type, airport characteristics, and project lifecycle phase. The report suggests the most appropriate measurement tools at various points in the project development cycle, for specific items in each element, and for different types of airports. The report does recognize that it is not practical to have one threshold that can be applied to all airports.

The report includes additional metrics that would be helpful in the future, one of which is better communication of delays to the general public. The report summarizes that these communications should be easily understandable, able to be used as a common measure at any airport, and applied consistently across all airports. It was also noted that using a more positive metric, such as level of service, rather than using a term such as delay, which has a negative connotation, would better serve the public and the industry overall.

The research, led by TransSolutions of Fort Worth, TX, was conducted under ACRP Project 03-20. The other team members and primary authors of the report included Futterman Consulting of St. Petersburg, FL, Harris Miller Miller & Hanson Inc. of Herndon, VA, and Jasenka Rakas of Berkeley, CA.
