This publication contains guidance for preparing plans and
specifications and for ensuring the quality of recycled bituminous
concrete. In addition, this manual provides useful information to
design engineers, laboratory personnel, and inspectors concerning
the mix design, plant production, and laydown of recycled pavement
mixtures. Recycling pavement materials has proved to be a feasible
process to rehabilitate worn-out pavements. Since recycled
pavements will not always be cost-effective, recycling should be
considered when repairing or rehabilitating existing pavements.
This report presents results on the demographics of safety belt use
from the 2003 National Occupant Protection Use Survey (NOPUS), with
particular emphasis on results that evaluate aspects of the 2003
Click It or Ticket campaign to raise safety belt use nationwide.
This study explores the relationship between vehicle occupancy and
several other variables in the National Highway Traffic Safety
Administration's (NHTSA) Fatality Analysis Reporting System (FARS)
database and a 15-passenger van's risk of rollover. A univariate
analysis is used to demonstrate the effect of selected variables on
single-vehicle rollover crashes. Variables used include speed,
number of occupants, driver experience and avoidance maneuvers.
Also, a logistic regression model is constructed using data from
NHTSA's State Data System - a collection of all police reported
crashes for that state. The resulting model permits jointly
estimating the effect of these variables on the odds and rate of
rollover occurrence, conditional on being in a single-vehicle
police-reported crash.
This report provides the results of a survey of State highway
agencies in the United States on partnering agreements with utility
companies and whether any have agreements similar to the Australian
MOUs. It also provides a step-by-step approach for developing an
Australian-type MOU in the United States, a sample MOU template,
and a sample conflict resolution matrix for handling differences
that may arise.
This publication provides an introduction to condition surveys,
maintenance and repair of street and roadway pavements.
This guide discusses the basic provisions of the conformity
process, including the following: (1) A description of actions
subject to conformity; (2) Frequency of conformity determinations;
(3) Key components of a conformity determination; (4) Consequences
of a failure to make a conformity determination; and (5) Roles and
responsibilities of public agency staff, management, policy
officials, and decision makers in the conformity process.
Blair Barnhardt's vision and goal is to create a movement across
this nation that will increase awareness and training for pavement
managers, politicians and everyday people that will in turn
resurrect our flailing roadway system with less money and less
carbon footprint. He is one of the few individuals that recognize
the enormity of the problem at hand, but also brings the practical
solution to solving it, hence The Book on Better Roads.
This publication will introduce you to the materials and methods
used to construct flexible pavements for streets, highways, parking
lots, and open storage areas. Flexible pavements are constructed
using bituminous (asphalt or tar) concrete. The pavement's
principal components are the subgrade, select materials for a
subbase course, the base course, and the bituminous concrete
pavement. This publication will introduce you to the important
characteristics of these components, and a design methodology that
will guide you in selection of appropriate material specifications
and course thicknesses.
This report was one in a series of pedestrian safety synthesis
reports prepared for the Federal Highway Administration (FHWA) to
document pedestrian safety in other countries. Australia is a
federation of States and Territories, and government
responsibilities broadly mirror that in the USA. Local government
is responsible for 80 percent of the road network, though the less
heavily traveled parts. Australia is highly urbanized
(notwithstanding large tracts of sparsely populated land). Almost
40% of the population lives in Melbourne or Sydney, and another 20%
in Brisbane, Perth, and Adelaide. Australia has been a pioneer of
traffic calming in the form of Local Area Traffic Management,
particularly in residential neighborhoods. Innovations are evident
in the traffic signal area. Puffin crossings with infrared
detectors seem promising. Pelican crossings are likely to find
ready application, and having them set up for double cycle
operations appears to offer benefits. Australia was particularly
innovative in developing the "safe routes to school" program, which
integrates education, route selection, and engineering treatments
to increase pupil safety. Also in development is the "walk with
care" program designed for the elderly.
This study estimates the effectiveness of passenger vehicle daytime
running lights in reducing two-vehicle opposite direction crashes,
pedestrian/bicycle crashes and motorcycle crashes. The author chose
the generalized simple odds, a conventional statistical technique,
to analyze the data.
