7. EXPLOITATION COSTS<br />
Exploitation costs, discussed in this<br />
paper, include the following costs:<br />
• fuel costs<br />
• costs of lubricants,<br />
• costs of pneumatics,<br />
• maintenance costs and repair of vehicles.<br />
The costs for fuel, lubricants, pneumatics,<br />
vehicle maintenance and repair are<br />
calculated according to the expressions [3]<br />
to the amount of (values in Table 9):<br />

8. COSTS OF TRAFFIC ACCIDENTS<br />
Total economic costs caused by all traffic<br />
accidents on the move of road in one<br />
year, are determined by the formula [3] :<br />
T su = L×<br />
∑ Nk<br />
× Ck<br />
(€/god)<br />
k<br />
where:<br />
k – indication of accident type<br />
( 1 –accident with deadly injuries;<br />
2 – accidents with serious body<br />
injuries; 3 – accidents without<br />
serious body injuries).<br />

Nk – average number of accidents per<br />
kilometer per year, for the certain<br />
types of accidents k (accident/km/year).<br />
This value depends<br />
on the type of road and<br />
AADT.<br />
L - length of a part of variant (km),<br />
Ck- average economic costs per accident<br />
for k – this type of accident<br />
(€)<br />
Overview of these costs is given in<br />
Table 10.<br />
9. IMPACT ON THE OVERALL<br />
DEVELOPMENT OF AREA<br />
Parameters that affect the overall development<br />
of the area have been avaluated<br />
through the following items:<br />
• route in the spatial conflict (conflict<br />
with regional plans is evaluated through<br />
the length of such track, or points);<br />
• preservation of existing settlements<br />
and encouragement of future urbanization<br />
(evaluation of points);<br />
• preservation of ugricultural and forest<br />
areas (is evalued by points);<br />
• the reality of performance, which is<br />
evaluated based on the need for resettlement,<br />
the possibility of obtaining<br />
the necessary material (for embankments),<br />
etc..<br />
Assessments for evaluation are given<br />
in Table 11.<br />
