Road Safety in Brief
Road safety issue has been the subject of study for many years
and with each passing day transportation engineering expands
this research area since it is a social matter of absolute priority.
The expression road safety is frequently used in the current
vocabulary of road users (as drivers or pedestrians), and road
professionals (as technicians, designers or managers), given that
the repeated occurrence of fatal, injury and property damage
crashes compromise the use of highways, streets and intersections
and the safety of the general community. Hauer [1] argues that the
road safety concept may be related to a property of the real-world
road units as road segments, intersections, vehicles, and users; each
road unit may be involved in crashes and crashes may happen on
it. When we think of ways to improve road safety, the associations
conjuring up are the reduction in crash frequencies and risky road
driving situations. Crashes are random events, rare when compared
to the millions of vehicles on the roads, events not reproducible a
posteriori, almost never observable if not when they have happened;
although many risky road situations continually happen on units
(road segments and intersections) of the road network, they don’t
always result in crashes.
