Mexico City Airport Airside Model

The airside VISSIM model for the new Mexico City Airport covers over 11,000 acres and contains 118 individual stands where planes are serviced by support vehicles (baggage, fuel, catering, etc). Because of the number of different configurations that we intended to test and the numerous repeating complex geometries, manual coding of the network would have taken a substantial amount of time and introduced potential errors and inconsistencies. I developed a library in Python to read VISSIM's text-based syntax, and automate the creation of the most complicated geometries as well as parking zones, transit lines and other infrastructure. This automation allowed us to test many more options and completely rebuild the model configuration in less than half the time it would if we had to make the changes within VISSIM's "point and click" interface.
