Query: Arterial incident duration prediction using a bi-level framework of
  extreme gradient-tree boosting   Predicting traffic incident duration is a major challenge for many traffic
centres around the world. Most research studies focus on predicting the
incident duration on motorways rather than arterial roads, due to a high
network complexity and lack of data. In this paper we propose a bi-level
framework for predicting the accident duration on arterial road networks in
Sydney, based on operational requirements of incident clearance target which is
less than 45 minutes. Using incident baseline information, we first deploy a
classification method using various ensemble tree models in order to predict
whether a new incident will be cleared in less than 45min or not. If the
incident was classified as short-term, then various regression models are
developed for predicting the actual incident duration in minutes by
incorporating various traffic flow features. After outlier removal and
intensive model hyper-parameter tuning through randomized search and
cross-validation, we show that the extreme gradient boost approach outperformed
all models, including the gradient-boosted decision-trees by almost 53%.
Finally, we perform a feature importance evaluation for incident duration
prediction and show that the best prediction results are obtained when
leveraging the real-time traffic flow in vicinity road sections to the reported
accident location.
