This thesis presents the procedure adopted to develop the priority rating system for highway safety improvements. Safety hazards are classified into four categories:
(1) Railroad crossings,
(2) Intersections,
(3) Geometric-Related Hazards, and
(4) Roadside Hazards.
For each category of hazards, relationships are developed to obtain a hazard index and expected...
This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
Many hazardous locations exist on our local and street highway
systems. Such hazards contribute to the frequency and severity of
traffic accidents. The elimination and mitigation of the hazards
reduces accident frequency and severity, as measured by the number of
fatalities, injuries and property damage resulting from the accidents.
The...
The western Taylor Park area covers about 65 square
miles on the western flank of the Sawatch Range. It is
underlain chiefly by Precambrian rocks, partially covered
on the east by glacial debris and overlapped on the west
and south by Paleozoic sedimentary rocks.
The Precambrian rocks include a group...
Three groups of experiments were performed to determine an effective
procedure for controlling decay in southern pine (Pinus spp.)
laminated timbers. (i) A decaying laminated arch of southern pine was
treated with chloropicrin. Movement of the chemical vapor through the
arch and its effect on the decay and nondecay fungal...
