Abstract:
Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people's answers are not very consistent and represent statements without any strong bearing on norms or behaviour. Many factors are 'pro-speed': higher performance vehicles, more comfort, media coverage, etc. Enforcement, particularly with cameras and with section control is efficient, but the scale of adoption is too small. Traffic calming is efficient in cities, but the most obvious measure is one that makes it impossible to drive faster than the speed limit. During the last 30 years, a few trials have taken place which are promising; speeds at or below the speed limit, improved behaviour, and attitudes. The predicted effect is a reduction of up to 50% of fatalities in a regulation-driven scenario and a benefit to cost ratio of 3.5 to 4.8. It is time for authorities to see to it that lower speeds with the help of efficient vehicle-based solutions becomes part of the agenda.
