• Point-to-point speed enforcement involves the calculation of the average speed over a section. • We evaluated the effects on speed and safety of the system on the urban motorway A56. • We observed reduction in speed, speed variability and non-compliance to speed limits. • The system yielded a statistically significant 32% reduction in the total crashes. • We developed crash modification functions which consider V m, V 85, and standard deviation of speed.
