No schmaltz !
The main research question is:
What are the safety consequences of “Do X” ?
X are possible decisions in Engineering, Planning, Regulation
and Policy
Consequences refers to the expected change in crash
number and severity (Crash Modification Factor, CMF)
# The role of research is to help provide correct information for
the deliberations that precede decisions.
# Research has value only in those societies in which it is
customary to base decisions on a rational-based anticipation
of consequences, including consequences of safety (CMF).

Why then is “More Accurate” = “Better” ?
(1). The importance of research on Road Safety
S. Cafiso – University of Catania
a. Research decreases the chance
of a ‘Do X’(or a Don’t Do X)
decision to be incorrect.
b. Incorrect decisions have a cost.
c. The value of more accurate
knowledge is the reduction of this
cost.
Area=P(Bad Decision│0.1)
Area=P(Bad Decision│0.5)
CMF
Why is ‘More Accurate’= ‘Better’?
Because, when the style is ‘Rational’, more accurate means that the chance of
making bad decisions and the cost of Implementing bad decisions are reduced.
