Research on Model Development for Freeway Safety Facilities

Table 1

Procedure of the deduction score determination of each damage.


1Collect the number of damage units for each freeway segment (one kilometer long) and the scores evaluated subjectively by the experts.

2Get the relationship of each safety facility between number of damage and the evaluating score by linear regression.

3Calculate the slope of the equation from Step 2 of each kind of safety facilities, which is the deduction score of each damage unit.

4Adjust the deduction scores according to the expert opinions and get the final results.
