Table 1 Efficiency of interventions implemented by the NRSPs in reducing the number of road traffic injuries or accidents: examples

1

Infrastructure: urban streets - reducing travel speed in cities by expanding 30 km/h zones

The Netherlands [43]

27% reduction in injuries

2

Infrastructure: rural single-carriageway roads - median guardrails, mostly of steel cables (“2 + 1”, “1 + 1” roads)

Sweden [26]

Risk of fatal or serious accidents was reduced by 75%-80%

3

Infrastructure: rural single-carriageway roads - overtaking lanes and median guardrails (“2 + 1”, “2 + 2” roads)

Finland [30]

Treatment of 130–200 km reduces 2–4 fatalities per year

4

Infrastructure: rural single-carriageway roads—rumble stripes in the middle

Finland [30]

Fatal head-on collisions were reduced by 10%–20%

5

Behaviors: speeding—enforcement by fixed cameras at hazardous locations

Sweden [14]

70% reduction in fatalities, 40% reduction in injuries

6

Behaviors: speeding—enforcement by fixed cameras

United Kingdom [35]

40% reduction in fatalities and serious injuries at locations with cameras

7

Behaviors: speeding—enforcement by fixed cameras

France [35]

Explains 75% of reduction in the number of fatalities in the years 2002−2005

8

Behaviors: driving under the influence of alcohol—enforcement by random checks

Sweden [2]

The increase in the number of checks led to annual savings of 15–20 fatalities and of 150–200 serious injuries
