10. EVALUATION CRITERIA AND<br />
THE APPLIED METHODS<br />
To determine the optimum variant, it is<br />
necessary to take into account all traffic<br />
and technical parameters and to form the<br />
criteria based on them.<br />
Measure of achievement the objectives<br />
can be expressed by defining the following<br />
criteria:<br />
• Minimum construction costs;<br />
• Minimum maintenance costs;<br />
• Minimum exploitation costs;<br />
Minimum<br />
impact on<br />
population<br />

factors<br />
the obstacles are overcome by<br />
bridges, overpasses and other overhead<br />
constructions.<br />

• Maximum security, safety and traffic<br />
comfort (which corresponds to<br />
minimum costs of accidents);<br />
• Maximum impact on development of<br />
the area;<br />
• Minimum spatial-ecological effects<br />
(which corresponds to maximum protection<br />
against impact of negative effects).<br />
