Impact of New Technologies

Is operation likely to lead to, or reduce, injury, theft or emissions (machine factors)?

• Protection of occupants• Ability to stop and manoeuvre (includes reliability and failure mode)• Compatibility with other vehicles/infrastructure.• Resistance to theft• Quantity and/or type of emissions

Is Human Machine Interface likely to lead to, or reduce, injury (human factors)?

• Ability of driver to operate effectively (operation, distraction)• Clarity of operation between different systems

Improved Performance – Technology that improves the performance of a vehicular system with new features or better outputs. Typical examples are traction control or intelligent airbags

• Intelligent Transport Systems (ITS) is a major grouping of technologies of this type

Improved Design – Technology that serves essentially the same purpose but operates in a very different way (eg mechanical systems replaced by electrical/electronic systems). Typical examples are steer-by-wire or LED lamps

Impact of New Technologies
