Using the Bayesian updating approach to improve the spatial and temporal transferability of real-time crash risk prediction models
We used Bayesian updating to improve transferability of real-time crash risk models. Real-time Crash risk models cannot be directly transferred across time and space. Bayesian updating can improve transferability even when new data are limited. Prediction accuracy of the updated model increases as new data sample size increases. Updating an existing model is better than developing a model when data are limited.
