The analysis of the number of passenger cars and lorries involved in accidents as a function of road-surface skidding resistance and hourly traffic volume. Paper and shortened version presented to the OECD Symposium on Heavy Freight Vehicles and thei...

In 1966 a working group on tyres, road surfaces and skidding accidents was set up in the Netherlands. The terms of reference of this working group included establishing the number of skidding accidents, and investigating the role that road-surface skidding resistance plays in accident occurrence. In this paper the interest is focused on the analysis of the involvement of lorries and passenger cars in accidents. The unit of investigation is the number of lorries (passenger cars) involved in accidents during a given time period, divided by the number of vehicle kilometres of that category of vehicles driven during the same time period.
