The assessment and evaluaon of the impacts caused by new highway, rehabilitaon or improvement
projects, in terms of the operaonal aspects of mobility and accessibility and the environmental
consideraons, have been eecvely promoted to the road development and transportaon
community since the late 1950’s. In contrast, the assessment and safety performance evaluaon of the
road geometric design and roadway condion alternaves has had limited progress in the state of the
pracce. The idencaon and selecon of roadway design elements and safety countermeasures
have relied substanally on recommended pracces or the intuive applicaon of the safety
treatments based on past experiences from local or naonal projects, without the use of data and
scienc methods.
Objcv of 1 Edo of Hgway Safy Maal
The Highway Safety Manual (HSM), published in the year 2010 by the American Associaon of StateHighways and Transportaon Ocials (AASHTO), provides highway engineers with a series of analycal
tools that incorporate quantave methods and the accepted procedures needed to esmate the level
of safety of future design alternaves at dierent stages of highway development projects. These tools
will allow highway agencies to establish eecve safety management systems through the use of
informed decisions sustained with crash and safety data and with the idencaon of the costs and
benets of the possible alternaves. (arcle connues on page 4)

Bicycles in the City: The Experience of the “Ciclo Vías”
EL PUENTE NEWSLETTER, VOL. 25, NO. 1, 2011 2
“Ciclo vía”, “ciclo ruta”, “bici -carril”, “carril -bici” or
“bici -senda” : Spanish terms given to bikeways, or
the part of the public roadway infrastructure or
other trails or paths reserved for the exclusive or
shared trac movements of bicycles, pedestrians,
skates, and other non-motorized transportaon
modes. The “Ciclo vía” could be placed on any
roadway lane that has been temporary signalized
for this purpose in a proper manner, or on an
exclusive right-of -way for the only purpose of
serving bicycle trac.
“Cclo Vía” Colomba
The “Ciclo vía”, as known in Colombia, is an acvity
held on every Sunday and public holiday in the
cies of Bogotá, Cali, and Medellín. The city of
Bogotá rst gave the name of “Ciclo vía” in 1975 to
the pracce of temporary closing of streets in the
major avenues of the city in order to provide
spaces to the populaon for recreaonal and sport
acvies during the weekends. The objecve of
the street closing was to also movate people to
travel in bicycle to the city to ride and play. There
are other recreaonal end entertainment events
along the “Ciclo vía”, such
as t workouts and
aerobics contests, extreme
sports, yoga classes, and
musical events.
The “Ciclo vía” in Bogotá
has a total length of 120 kilometers of routes
and is being held on
Sundays and public holidays from 7AM to 2PM.
Tipically, near 2 million people enjoy the acvies.
During special holidays, such as Christmas, the
“Ciclo vía” is organized for the enre day, ending at
midnight.
“Cclo Vía” Méxco
Mexico City has developed three “Ciclo vía”
circuits in the urban area. One of the circuits has a
total length of 59 kilometers, and is located over
the right of way of the México – Cuernavaca
Railroad, going from the “Ejército Nacional ”
Avenue in the Polanco neighborhood to the “Fierro
del Toro” neighborhood in the State of Morelos.
Another circuit was opened in the Chapultepec
Park going over three secons of the park. The
third circuit goes from the Chapultepec Park to the
“ Zócalo” area in Mexico City through the “Paseo
de la Reforma” Avenue. The “Paseo de la
Reforma” is one of the most important and
congested avenues in the city, providing evidence
of the government commitment with non-
motorized transportaon alternaves and
recreaonal opons to the residents of this 20
million metropolis.
Other cies in Mexico, like Guadalajara, have
follow the example of the Federal District
successfully implemenng the “Ciclo vía” concept.
The Region of Ixtapa-Zihuatanejo has integrated
the “Ciclo vía” with the natural features of the
region connecng
the resort area in
Ixtapa through the
coastal area. The
region of
Tulancingo has ve
“Ciclo vías” thatcross the cies of
Tulancingo, Sanago
Tulantepec and
Cuautepec de
Hinojosa.
“Cclo Vía” Madrd, Spa
Madrid has had dicules implemenng the “Ciclo
vía” concept due to the belief of the governments

that the city of Madrid was not built for bicycle
travel. The Madrid Pro-Bici Associaon,
composed of dierent stakeholders of bicycle
groups in the city, was created with the objecve
of promong the use of bicycles in the city and
inform the government about the “Ciclo vía”
experience in other cies. Today, Madrid has
implemented many kilometers of bikeways
surrounding the city with the expectaon of
establishingbike staons
throughout
Madrid.
“Cclo Vía” Ud Sa
The city of Cambridge, Massachuses, opens its
Memorial Drive Avenue for the exclusive
movements of bicycle and pedestrian trac
during Sundays between the months of April and
November since the 1990’s.
The city of New York carried out “Ciclo vía”
acvies through three Saturdays in the years
2008 and 2009, converng around 7 miles of
roadways, from 96th Street to the Brooklyn
Bridge, to exclusive bicycle and pedestrian routes
from 7AM to 1 PM.
The city of Miami had its rst “Ciclo vía” , called
Bike Miami , in November 2008. Miami became
the rst city in the United States in March 2009 in
having ve “Ciclo vía” acvies. This monthly
acvity called Miami Days looks to promote
livable streets and a sustainable city, in addion
to promong people to walk and use the bicycle
as transportaon
opons.
The city of San
Francisco carries
out “Ciclo vía”
events called
Sunday Streets since 2008. This monthly acvity,
held during a Sunday, consists of closing out 3 miles
of the Embarcadero Street to motorized trac. In
addion to the “Ciclo vía” , there are dierent
acvies held
along the street,
like bike riding
lessons, dance
classes, musicevents,
entertainment
machines and
kiosks with food
samples from street merchants.
T “Cclo Día” Poc, Pro Rco
The Municipality of Ponce held its “Ciclo día” event
on January 16, 2011, as part of the transportaon
project called “Sistema Integrado de Transportación
del Sur” (SITRAS), that is expected to start
operaons by summer.
The system will connect
dierent neighborhoods
with the urban district of
the city by using buses
and tourist shules,
providing daily service
for 12 hours free of
charge.
The integraon of the “Ciclo vía” to SITRAS was the
starng point to the “Ciclo Día” event, serving as a
rehearsal. This acvity is planned to be held
monthly, by peon of those persons that have
made the bicycle part of their roune and quality of
life.

HSM CONTENTS
The HSM is organized in four parts:
Par A - Includes an introducon to HSM and
provides the scienc basics associated with the
human factors and theorecal concepts that areincorporated in the tools and analycal
methods.
Par B - Includes the tools and methods
necessary to support the highway safety
management systems. These chapters contain
informaon about how to perform an
assessment of the road network, how to
perform the diagnoscs of the safety issues and
how to idenfy and perform the economic
evaluaon of the safety countermeasures. In
addion, this part contains tools to establish
priories between the road alternaves and
how to assess the eecveness of the safety
measures.
Par C - Includes the predicve methods with
the applicaon of safety performance funcons
for:
Two-lane rural highways,
Mulple lane rural highways, and
Urban and suburban arterials.
Par D - Includes the crash modicaon factors
(CMF) that were available in 2007. The included
CMFs in the HSM were submied to a rigorous
assessment to assure their validity for the
evaluaon of the safety performance. CMFs
were included in the HSM for the following
condions:
Road segments,
Intersecons,
Interchanges,
Special facilies, and
Highway networks.
For more informaon about HSM and how to
purchase the manual please visit the AASHTO
Internet site at:
The HSM is the direct result from the compleon
of mulple recent scienc research studies.
These studies were directed to the idencaon
of the roadway crash frequency and severity
factors for dierent highway funconal classes.
In addion, the HSM uses analycal tools for the
evaluaon, analysis, and assessment of thesafety impacts from road design alternaves.
The development of the HSM was carried out by
a group of experts from the Transportaon
Research Board, the Naonal Cooperave
Highway Research Program, and researchers
from renowned universies that helped establish
the scienc focus of the Manual.
Instead of being prescripve, the HSM provides
tool that can predict the crash reducon
potenal of safety decisions taken during the
road planning, programming, design, operaonor maintenance stages. These tools are
presented in the Manual by discussing their
strengths and limitaons.
The HSM is directed toward highway engineering
ocials, from state, county and local agencies,
and regional and metropolitan planning
organizaons in the United States.
HSM APPLICATIONS
The expected benets from the implementaon
of the HSM should include reducons in road
crashes and costs due to the enhancement of the
decision making process and the eecveness of
the selecon process of safety countermeasures
made by highway engineers.

Safety Principles for Flaggers on Highway Work Zones
EL PUENTE NEWSLETTER, VOL. 25, NO. 1, 2011
The Right Training
Flaggers play a fundamental role in keeping the safety of road users and the personnel working on or near roadways.
Near to 20 aggers die annually aer being hit by a motor vehicle going through a work zone or by machinery located
within the work zone; while much more aggers are severely injured. The Manual on Uniform Trac Control Devices
contain rules and guidance that all aggers must know in order to carry out his/her dues in a safe and eecve manner.
All aggers must know the following 6 safety principles on work zones and for temporary trac control dues.
The Right Signals
TO STOP TRAFFIC
TO LET TRAFFIC PROCEED
TO ALERT AND SLOW DOWN
TRAFFIC
The Right Advanced Warning Sign Spacing
A
B
The selecon of signs, their message and
spacing vary depending on factors such as the
work type and duraon, highway class, trac
volume, road geometry, speeds and other
condions. Verify MUTCD for guidance.
The Right Trafic Control Plan
The MUTCD and the Standard
Drawings include typical applicaons
of trac control plans for dierent
types of highway work zones.
Stand on the shoulder in a visible place. Always face trac. Use hand signals in combinaon with
the agger paddle or the red ag. Be always alert and focused on trac
control dues. Be polite with road users.
The Right Practices Always be located at the agger staon. Have a radio or other communicaon
device with your work group andsupervisors.
Plan an emergency escape route.
Never be distracted with cell phones,music radio, MP3 or IPODs.
Always use high visibility safety
garment that comply with
standard ANSI/ISEA-107 Class 2
or 3.
The Right Garment and Gear Always use agger paddle or automated
agger assistance devices. Always have
available a radio, and overhead lamps for
nighme work.

Highway fatalies had an average reducon of 10% in the United States, as in Puerto Rico, between the
years 2008 and 2009. Nevertheless, a total of 33,808 persons lost their lives as a consequence of a
highway related crash in the United States. At the same me, a total of 365 highway related fatalies
were recorded in Puerto Rico for an average of one live lost per day.
All safety iniaves directed toward reducing road related fatalies are require to focus on the exisng
condions on rural roads and roads of lower funconal classicaons to accomplish substanal results.
Fatalies on rural roads accounted for 57% of the total number of fatalies in 2009; meanwhile, 38% of
the fatalies occurred on collector and local type roads in Puerto Rico.
The Safety Oce of the Federal Highway Administraon has taken a leading role to promote naonally
the need to analyze and evaluate rural and local road safety. To accomplish this objecve the Safety
Oce has made available online a series of tools and resources to assist engineers and transportaon
ocials in charge of local and rural highway systems.
