Elvik, Rune; Høye, Alena (Journal article; Peer reviewed, 2023-01-30)This paper compares the results found in successive accident prediction models developed at the national level for Norway. Over time, the models have become more comprehensive in terms of the roads and the variables included ... -
Descriptive analysis of reports on autonomous vehicle collisions in California: January 2021–June 2022
Pokorny, Petr; Høye, Alena (Journal article; Peer reviewed, 2022-09-28)The characteristics of autonomous vehicles’ collisions from 2021 and the first half of 2022 in California confirm trends reported in previous years. Driving in autonomous mode was associated with fewer instances in which ... -
Do we know why the number of traffic fatalities is declining? If not, can we find out?
Elvik, Rune; Høye, Alena (Journal article; Peer reviewed, 2022-06-07)The number of traffic fatalities has declined by 80-90 % from the all-time peak number in many highly motorized countries. It would be of great interest to identify factors that explain this decline. Unfortunately, this ... -
