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...
This study defines the information gathering and communication and response
needed for safety at highway-rail crossings. It examines technologies for low-cost,
high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing
train control and crossing safety systems...
This study presents a rational process with supporting data to establish
appropriate road design controls, criteria, and standards for low volume
recreation and resource development. Much of the information presented can
be used to supplement design data presented in a National road design policy
published by the American Association of...
Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors....
Evaluation of the safety hazards along a highway is usually
performed at specific locations and on known hazards. But, it is also
important to find any unrecognized hazards and their locations. Many
factors contribute to accident potential, and the combined effect of
several of them could produce a hazard that...
The development of a pavement management system for low-volume roads is a difficult task. There are many interrelated activities that must be considered, such as planning, design, construction, maintenance, and pavement evaluation. This paper addresses the evaluation and maintenance components of a pavement management system for low-volume roadways and provides...
