文摘
- •
Nonlinear safety performance functions fit the signalized intersection crash data better.
- •
Used generalized additive models to identify appropriate safety performance functions.
- •
It is important to consider the joint safety impacts of major- and minor-approach AADTs.
- •
Generalized additive models with isotropic smooth perform the best.
