Paper Summary

The study simulated road accident data to see how well different models predict accidents in T-junctions. They used two types of models, Poisson and negative binomial, with varying sample sizes. The results showed that not all models fit the data perfectly, especially with larger sample sizes. Additionally, larger sample sizes tended to have more instances of zero accidents recorded.
