Modeling 911 emergency events in Cuenca-Ecuador using geo-spatial data
(CITT 2018, 2019) Robles Granda, Pablo Dario; Tello Guerrero, Marco Andres; Zúñiga Prieto, Miguel Ángel; Solano Quinde, Lizandro Damián
We present several techniques for modeling emergency events using data from 911 emergency calls in the city of Cuenca-Ecuador. We apply three types of models. First, we use a probabilistic description of events using Gaussian kernels based on both, regular segmentation and mixture models, to represent the spatial distribution of occurrences. Second, we verify the qualitative relation of the clusters obtained with our kernel model with respect to the geo-political organization of the city. Finally, we develop an emergency model using a large dataset corresponding to the period January 1st 2015 through December 31st 2016 and test various data mining algorithms for prediction purposes. We verify the usefulness of our approach experimentally.

Temporal analysis of 911 emergency calls through time series modeling
(Springer, 2020) Robles Granda, Pablo Dario; Tello Guerrero, Marco Andres; Solano Quinde, Lizandro Damián; Zúñiga Prieto, Miguel Ángel
We present two techniques for modeling time series of emergency events using data from 911 emergency calls in the city of Cuenca-Ecuador. We study state-of-the-art methods for time series analysis and assess the benefits and drawbacks of each one of them. In this paper, we develop an emergency model using a large dataset corresponding to the period January 1st 2015 through December 31st 2016 and test a Gaussian Process and an ARIMA model for temporal prediction purposes. We assess the performance of our approaches experimentally, comparing the standard residual error (SRE) and the execution time of both models. In addition, we include climate and holidays data as explanatory variables of the regressions aiming to improve the prediction. The results show that ARIMA model is the most suitable one for forecasting emergency events even without the support of additional variables.
