Objectives:

To refute a number of myths hindering ISA implementation.

Methodology:

Review

Key Findings:

  • ISA is a mature technology — ISA systems are robust and reliable.

  • The provision of up-to-date speed limit data is complex, but achievable. There are issues about delivery of the information to end users, i.e. drivers.

  • Research has found that, in cost-benefit terms, gains substantially outweigh the costs of ISA implementation.

  • ISA does not mean that complete control is taken away from the driver. The driver is still responsible for the control of the vehicle and ISA technologies are merely a tool to enable the driver to comply with the speed limit.

  • Drivers generally recognise the risks involved in driving too fast and support measures to reduce speeding.

  • Exceeding the speed limit is a significant contributor to RTIs and speeding is often linked to other risky behaviour.In addition to its benefits for vehicle occupants, ISA can make a substantial contribution to improving the safety of other road users such as pedestrians and cyclists.
