Neural networks trained with WiFi traces to predict airport passenger behavior
This work addresses airport management and passenger flow optimization, but it is incremental as it applies existing neural network methods to a new dataset.
The paper tackled predicting airport passenger activity choices using neural networks trained on WiFi traces, finding that an LSTM approach outperformed feedforward networks for short-term predictions (20 minutes or less).
The use of neural networks to predict airport passenger activity choices inside the terminal is presented in this paper. Three network architectures are proposed: Feedforward Neural Networks (FNN), Long Short-Term Memory (LSTM) networks, and a combination of the two. Inputs to these models are both static (passenger and trip characteristics) and dynamic (real-time passenger tracking). A real-world case study exemplifies the application of these models, using anonymous WiFi traces collected at Bologna Airport to train the networks. The performance of the models were evaluated according to the misclassification rate of passenger activity choices. In the LSTM approach, two different multi-step forecasting strategies are tested. According to our findings, the direct LSTM approach provides better results than the FNN, especially when the prediction horizon is relatively short (20 minutes or less).
