Intermediate outcome targets
Intermediate outcome targets
Intermediate outcome targets are used in several countries e.g. New Zealand and Canada to help achieve final outcomes. They can include targets to reduce average traffic speeds, to reduce the proportion of drunk drivers in crashes or on traffic, to increase seatbelt and helmet wearing rates, to improve the physical condition of the road network or the standard of the vehicle fleet or the quality of post-crash services.
In Canada, the national target calls for a 30% decrease in the average number of road users killed or seriously injured during the 2008-2010 period compared with 1996-2001 average figures. A range of sub-targets or intermediate outcome targets were set.
Intermediate outcome targets in the Canadian road safety strategy (CCMTA, 2002)
- A 95% rate of seat belt wearing and proper use of appropriate child restraints by all motor vehicle occupants
- A 40% decrease in the number of fatally or seriously injured unbelted occupants
- A 40% decrease in the percentage of road users fatally or seriously injured in crashes involving drinking drivers
- A 40% decrease in the number of road users fatally or seriously injured on rural roadways (defined as roads where the speed limit is 80-90 km/hr).
- A 20% decrease in the number of road users killed or seriously injured in speed or intersection-related crashes.
- A 20% decrease in the number of road users killed or seriously injured in crashes involving commercial vehicles
- A 20% decrease in the number of young drivers/riders (those aged 16-19 years) killed or seriously injured in crashes
- A 30% decrease in the number of fatally or seriously injured vulnerable road users (pedestrians, motorcyclists and cyclists).
- A 20% decrease in the number of road users fatally or seriously injured in crashes involving high-risk drivers
| Intermediate outcome targets for speed, excess alcohol and restraint use in New Zealand's Road Safety to 2010 strategy against 2001 baseline (LTSA, 2003) | Target |
|---|---|
|   | 2004 |
| Speed | not exceeding |
| Open road mean speed (km/h) | 99 |
| Open road 85th percentile (km/h) | 107 |
| Urban mean speed (km/h) | 55.2 |
| Urban 85th percentile (km/h) | 61 |
| Alcohol |   |
| Percent of driver deaths with excess alcohol | 21% |
| Number of driver deaths with excess alcohol | 48 |
| Restraints | At least |
| Seat belts - front | 92% |
| Seat belts - rear | 75% |
| Children (under 15) restrained | 90% |
Such targets can help to provide focus for multi-sectoral interventions and resource and provide the opportunity for closer management of activity within the national strategy towards achieving headline outcome targets.
In Europe to date, intermediate outcomes have usually been monitored rather than targeted in national road safety strategies.
