Safety

Current consensus

The safety impact area addresses how the CCAM system or service under study influences traffic safety by examining the change in the number of fatalities, injuries, and accidents.

Explanation

Safety is absense of fatalities or injuries in traffic. It can be measured as number of fatalities or injured persons of an entity (i.e. area, road section, road user group, vehicle) in a unit of time. The number of fatalities and injuries depend on three dimensions: exposure (activity where accident can occur), risk (accident rate per exposure unit) and consequence (severity of accidents). Safety depends on interactions between and within the three dimensions and the interactions between different parts of the transport system (traffic environment, vehicle and road users).
