rising road congestion problems
as more people began to own personal
cars the demand for effective road
congestion control grew
roadways across the united states are
required to become more adjustable and
acceptable for drivers as observed in
recent disturbing data that pushed civil
engineers to devote more time and
attention to the problem
road congestion grew by six percent with
the average driver wasting up to 200
plus hours of travel over the course of
a year
this was an average of traffic hours
with some cities doing better and other
cities doing worse during the year
the worst city for traffic congestion
was reported as los angeles where the
typical driver spent up to 167
hours per year stuck in traffic
at the bottom of the list san jose did
considerably better with drivers
spending only 81 hours per year stuck in
traffic
researchers are investigating the
fundamental causes of traffic congestion
and how they might be relieved to tackle
this problem
proposed plans
fixing two-lane highway traffic and
safety conditions is important to the
traffic which has received major
research attention in the previous
decade
to improve traffic safety performance
under current conditions several
cost-effective and proactive
alternatives such as low-cost treatments
and highway safety monitoring programs
have been created
based on the suggested assessment
criteria
potential causal factors are expressed
and key countermeasures against bad
driving conditions such as abrupt bends
steep slopes continuous downgrades low
sight distance and inadequate clear
zones are developed
five low-cost engineering innovations
were adopted expressly to increase
two-lane highway safety
smart road design
strategies are being explored to add
more functionality to the actual road
surface which might improve traffic and
give safety elements that would minimize
not just injuries and casualties but
also accident scenes that cause
congestion
a piece of roadway in the netherlands
has been transformed into a trial area
for smart highway features as one
example
the initial phase involves simply mixing
the solar charged photoluminescent
powder into the road paint to make lane
line shine in the dark at night
increasing visibility in a region where
lamps are frequently shut off late at
night
temperature sensitive signs on the road
surface to inform drivers of weather
situations wind indications and even
embedded inductive coils to recharge
electric cars as they pass over are all
suggested improvements
solar roadways which is being designed
by a husband and wife partnership is
another unique road surface invention
that is getting popularity in the united
states
solar cells have been incorporated into
panels that have been blended and
utilized as highways by scott and julie
brewsaw
we're constructing solar panels that you
can drive on
they were awarded a contract to test
their system in an idaho parking lot
and the project was completed in 2013.
the original prototype's performance was
unsatisfactory but the company is
pressing through with testing along a
section of historical route 66 in
missouri as of 2016.
despite its rough start engineers
renewable power investors traffic
planners and other experts have praised
the concept
as demand for alternative energies and
electric cars grow the concept may
receive more attention and
implementation
pavement markings
at the general parts night performance
pavement markings like yellow lane lines
and white edge lines were painted
at the junctions guiding lines wording
crosswalks and symbol markings were
installed
sharp bends or sights prone to accidents
were marked with thin red lines painted
vertically
at lane boundaries and lane mediums for
walkers optical illusion deceleration
markers were painted to inform vehicles
of unique geometric situations
alternative transportation
infrastructure
towns and infrastructural planners have
realized the need of providing the
infrastructure required to assure the
safety and efficiency of alternative
transportation systems to boost their
use
cycle paths carpool lanes bus only lanes
bus tunnels tram or streetcar lines and
other amenities are being built in
cities across the united states and
around the world
the degree of separation between these
sorts of designated alternative transit
infrastructures and normal car lanes
according to an article gathered by
crowdsource transport increases the
degree of effectiveness projected
as a result entirely separated lanes or
exclusive areas rather than just
painting lanes or signs on existing
pavement are more successful in reducing
traffic congestion
over the next few years transit design
will become an increasingly important
aspect of urban planning and
regeneration activities
roadside barriers
let me tell you that runoff road
collisions accounted for nearly 20
percent of all accidents on the roadway
in many particular portions along the
highway fifteen thousand one hundred and
thirty seven meters of barriers were
installed or changed based on the degree
of roadside danger accident rate
operation speed the volume of traffic
and composition and landscape need
one of the most important strategies we
used was the forgiving design principle
in other situations however barrier
equipment was required due to terrain
characteristics
at portions of small continuous
horizontal bends and regions with a high
frequency of side contact accidents a
total of 2
850 meters of high-strength concrete
blocks were fixed beside cliff edges
at severe horizontal curve parts
serrated concrete blocks with light look
were created for guidance resulting in
fewer collisions
at cliff portions windrows and high
concrete blocks with insufficient earth
pressure outside of the shoulder a total
of
5158 meters of curved beam barriers or
metal guard rails were constructed
downgraded portions with greater
operating speeds and severe impacts of
rollover accidents were selected for a
level corrugated beam barriers
for renovated areas with a decreased
risk of collisions b level barriers were
constructed
outside of the shoulder a total of 7
129 meters of cable barriers were
installed
to make obstacles more visible yellow
reflectors were put on them
a level protection barriers were
installed in locations with a history of
rollover accidents or higher risk
coefficients whereas b level cable
barriers were installed in areas with no
history of rollover accidents or
roadside shallows

public transportation investment
the public interest research group of
the united states published in-depth
research highlighting the need for more
investment in public transit across the
country
increasing public transportation use has
been cited as the way to reduce oil
consumption traffic congestion and our
nation's environmental imprint
there have also been suggestions of the
improved quality of life and cost
savings that come with not having to own
a vehicle
investing in public transportation will
also stimulate employment development
more effective than investing in highway
maintenance or infrastructure projects
while city planners and local
governments routinely analyze major
public transportation overhauls due to
perceived high costs often less is more
even current public transportation
infrastructures might be reimagined to
provide entirely new possibilities that
not only address a wide range of
pressing issues but also give the
capacity for expansion for towns cities
states countries and beyond
as a result of a convergence of several
elements the area of transportation
engineering and innovation is expected
to accelerate to new heights of
significance and demand
here it is worth pointing out that the
increasing need for better public
transportation will be driven by rising
national and international populations
increasing demand to reduce dependency
on fossil fuels lowering prices of
alternative energy and technologies and
slow but steady social behavior shifts
forcing more and more people towards
alternative lifestyles that diminish
personal car ownership
that's all for today
