What is it about?
The study developed a statistical model using exposure and geometric design variables to predict accidents on the A29 motorway in Portugal, using data from 2015-2019. Key factors influencing accidents include horizontal curvature, presence of deceleration lanes and annual trends. The model was validated using cumulative residual plots, showing good performance in predicting accident frequency.

Why is it important?
Highway safety is very important for several reasons. Road Safety analysis helps identify key geometric design factors that contribute to accidents, allowing for targeted improvements. Reducing accidents can significantly lower the economic and social costs associated with road accidents. The model acts as a decision support tool for implementing effective road safety measures.
Perspectives
Recommendations include expanding the study to other motorways and developing more comprehensive models for better road safety management. Future lines of research contemplate expanding the model to a greater network
