Abstract:
The main purpose of this research was to investigate the vehicle behaviors and effectiveness and effeciency of services at passenger dropping off area in front of departure terminal. The improvement for increasing effectiveness was also explored to cope with traffic congestion problem, which occurs during peak hours. In order to examine service effectiveness, effectiveness measures, dynamic capacity model, and computer simulation model were used for analysis. The data of this study were composed of physical information of service area, traffic data, and service behavior data, which were collected at dropping off area in front of International Departure Terminal 1 of the Bangkok International Airport. From site surveying, it was found that the peak hour is from 9.30 P.M. to 10.30 P.M. on Friday. The main causes of traffic congestion problem are car parking for a long period of time and nonuniform car distribution along curbside area. This research found that area performance effectiveness, which used walking disutility for indicating, falls within high level range. As for service effectiveness, which was specified by degree of curbside utilization, falls in medium level range and finally, capacity effectiveness, which used dynamic capacity model for enumerating, fall in low level range. The result from model validation testing was not within statistical acceptable range, thus some improvements should be made.
