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

7/29/2019 Vol 25 No 012011


PUERTO RICO TRANSPORTATION TECHNOLOGY TRANSFER CENTER 3

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.
