This analysis provides a level of comparative validation that the parameters adopted
within the assessment of the Elm Street / Diamond Street intersection are appropriate
and considered as close as practicable to the existing traffic operations, and generally
consistent with the parameters recommended in DMR’s “Road Planning and Design
Manual”.
