Traffic prediction at signalised intersections using Integrated Nested Laplace Approximation

  title={Traffic prediction at signalised intersections using Integrated Nested Laplace Approximation},
  author={Deanna Townsend and Christopher Robert Nel},
A Bayesian approach to predicting traffic flows at signalised intersections is considered using the the INLA framework. INLA is a deterministic, computationally efficient alternative to MCMC for estimating a posterior distribution. It is designed for latent Gaussian models where the parameters follow a joint Gaussian distribution. An assumption which naturally evolves from an LGM is that of a Gaussian Markov Random Field (GMRF). It can be shown that a traffic prediction model based in both… 


Non-stationary Gaussian models with physical barriers
The Barrier model is a non-stationary model based on viewing the Matern correlation not as a correlation function on the shortest distance between two points, but as a collection of paths through a Simultaneous Autoregressive (SAR) model, which is easy to use, and can deal with both sparse data and very complex barriers.
Spatial and Spatio-temporal Bayesian Models with R - INLA
DESCRIPTION Spatial and Spatio-Temporal Bayesian Models with R-INLA provides a much needed, practically oriented & innovative presentation of the combination of Bayesian methodology and spatial
