Breakaway Sign Posts, Color
Make for Safer Roadways
By Arthur M. Dinitz
Color pavement lanes provide unambiguous
guidance for users, resulting in safer roadways
ountries throughout the
world are seeking ways
to increase safety and
compliance with traffic laws
on roads and highways, reducing the
number of fatal or serious injury crashes
into roadside signs and streetlights,
improving traffic flow and pedestrian
safety with traffic calming methods
and clearly defined preferential lanes,
and areas that have proved to increase
visibility and reduce unauthorized use.
This all boosts safety especially in cities
with high traffic flow.
In the United States, the history of
"breakaway" posts for signs and street
lighting goes back a half-century. In the
1960s, roadside hazards were identified
as a major cause of fatalities and serious
injuries. It became evident that if the
obstacle could not be removed it should
be made breakaway; or if it could not be
made breakaway, it should be protected.
Sign supports usually are located
immediately adjacent to roadways, and
are subject to impact by errant vehicles
and must yield or breakaway if struck.
Since the 1970s in the United States,
omni-directional breakaway couplings
such as the post support have become
the standard for many states, and
thousands of lives have been saved.
Global interest in breakaways is
increasing. In Israel, highway safety
support structures have been used for
over 20 years. Dozens if not hundreds
of accidents have been witnessed
with no fatalities or serious bodily
harm injuries reported on light poles
using omni- directional breakaways.
New Zealand, Australia and Canada
have begun to use omni-directional
breakaways and there is increasing
global interest in this technology.
Research suggests 70 percent of onevehicle fatalities involves cars leaving
the roadway and either overturning, or
colliding with fixed objects. Breakaways
for ground mounted signs and
luminaries can significantly decrease
the severity of these accidents and
One of the key issues to ensuring
greater safety in transport is to identify
and treat hazardous locations and
objects. By using omni-directional
breakaway supports that are designed
to break away quickly and cleanly upon
impact, with consistent, predictable
behavior, regardless of the vehicle's
angle of impact, reduced property
damage and saving lives will result.
More and more people are using
bicycles as a means to travel around
urban areas. Along with this increase
in bicycle use the close proximity
of bicycles and vehicles has caused
engineers and planners to reconsider
the safety of both types of users.
Colored pavements can isolate bike
lanes as well as inform riders of bus
route locations, while alerting motor
vehicle operators of the special -use
lane. In cities around the world bus lane
violations are being reduced with color
In the USA over 4,000 people are
struck by motor vehicles each year.
and many cities have been dedicating
their resources to reducing this figure.
Choosing the proper material will result
in durable, cost-effective solutions.
