Visualize the Catchment Areas of Albert J. Ellis Airport (OAJ)

Note for using this tool

This tool shows how airport catchment areas change based on different itineraries departing from Albert J. Ellis Airport (OAJ) and nearby airports.
It assumes that travelers choose the departing airport that offers the highest utility, with utility measured by the overall cost of the itinerary.
In this context, higher utility corresponds to lower cost.

The calculation of travel utility is based on the method introduced by Gao (2020) doi.org/10.1016/j.jtrangeo.2019.102628
Total cost = ground access cost + flight cost + parking cost (for self-driving)

To utilize this tool, navigate through four tabs and provide the required input information for Trip, Airfares, Flying Time, and Parking.
1. Trip: Enter the overall trip information here.
For the value of travel time savings (ground component), follow Gao's (2020) recommendations of $21/hour for leisure travel and $28/hour for business travel.
For the value of travel time savings (air component), use $39/hour for leisure travel and $63/hour for business travel.
2. Airfare: Enter the airfare for the itinerary departing from a specific airport.
If no flight option is available from an airport, keep $9,999 as the airfare for that airport.
3. Flying Time: Enter the total flying time, including layovers between flights, for each itinerary departing from different airports.
If no flight option is available from an airport, keep 99 hours as the flying time for that airport.
4. Parking: Enter the daily parking rate for each airport (assuming economy parking option).
If no flight option is available from an airport, keep $99 as the parking rate for that airport.

Catchment area plot: The catchment area map is color-coded.
Blue indicates that a census tract lies outside of OAJ's catchment areas, while ivory, orange, or red indicates that a census tract is within OAJ's catchment areas.
