Model of Airport Employee Access Traffic

Previous research on airport access has not focused adequate attention on airport employee traffic considering that airports employ nearly one person per daily enplaned passenger. This paper provides a tool that can be used to estimate employee traffic volumes in specified time intervals as a function of employee work shift characteristics. Inputs to the model include work-shift times, the number of employees per shift, probability distributions for the times at which employees actually arrive at and leave work, and the average number of employees per vehicle. The model is designed for use in conjunction with models of air passenger and visitor traffic. In particular, it can be used to investigate the potential for mutual interference of employee traffic peak and air passenger traffic peaks. A demonstration of the model is presented using data collected at the Dallas/Fort Worth Regional Airport; model estimates are compared with actual traffic counts of employee vehicles.
