Zusammenfassung:	•This study develops Safety Performance Function (SPF) analyzing cumulative residuals for two-lane rural highways.•On the basis of cumulative residual analysis the sample were divided on ranges of the AADT variable for obtaining better models.•In the AADT>4000veh/day database the percentage of heavy vehicles and the curvature change rate (CCR) have a large effect on the crash frequency.•In the AADT
