The objective of this study is to assess the introduction of 21 vehicle safety technologies based on existing literature, data and knowledge.


The economic cost-benefit assessment compares the costs of installing the relevant technology in all relevant new vehicles with the benefits for society of doing so in terms of reduced numbers of fatalities, severe injuries and slight injuries.

The estimated effects on the number of fatalities, severe injuries and slight injuries are based on:

  • Existing studies;

  • RTI data;

  • Estimates of the effectiveness of the technology in terms of reducing the risk of RTI and/or the severity of injuries in case an RTI occurs; and,

  • A scenario for implementation (market penetration in the Do-something scenario and the Do-nothing scenario).

Key Findings:

  • Electronic Stability Control (ESC) has a benefit/cost ratio (BCR) of 3.8, and is deemed to be cost effective.

  • Intelligent Speed Adaptation (ISA) has a BCR of 3.3 and is deemed to be cost effective.

  • Daytime Running Lights has a BCR of 1.8 and is most likely cost effective.

  • Adaptive Cruise Control (ACC) has a BCR of 0.4, most likely not cost effective.

  • Brake assistant systems have a break even cost/benefit.

Useful indication of the effectiveness of each technology in terms of cost and benefits. Results are based on a number of assumptions.
