For the purposes of this synthesis adult pedestrians are defined as those aged 16 to 59, which is the age range commonly used to describe adults in the ‘Reported road casualties Great Britain’ reports. Where some authors of other research have used different age bands, these are clearly stated.
Pedestrians face specific road safety problems:
Vulnerability – pedestrians lack physical protection, sub-groups such as older pedestrians may be especially frail
Conspicuity – pedestrians are small compared to vehicles
Effort – pedestrians are self-propelled and effort associated with making a detour results in direct desire line
Distraction – pedestrians are often also engaged in other activities
