Assessment of Curbside Roadway Level of Service of The Bandaranayke International Airport – Sri Lanka: A Comparison of The Analysis Tools in ACRP 40

Abstract

This study utilizes the most recent data set available on Bandaranaike International Airport Curbside Operations, collected in 2012, in assessing the curbside roadway level of service. The level of service of both the departure and arrival curbside roadways are evaluated using the guidelines presented in the ACRP 40 report on Airport curbside and Terminal Area Roadway Operations. This study compares the two evaluation procedures suggested in ACRP 40 where only one vehicle type is assumed and where the actual vehicle configuration is taken in to account and the factors affecting the differences are discussed. Upon unavailability of an exact method/function to obtain the factor to derive design stall requirement from the calculated stall requirement, an appropriate function was developed to predict required values in the calculation. The LOS of the BIA for the given data set was derived as E for both arrival and departure curbs which is different from the previous study done by Sameera using the same data set. Consideration of the vehicle configuration found to have affected the difference of the outcome mainly. The through lane level of service did not affect the outcome.
