INFOVIAL. The system
was developed by
Signal Group and
provides the
agency with
real-time traffic
conditions for
350km of major
roads in Mexico
City, allowing
the agency to
react in a more
timely and
efficient manner
when unexpected
traffic conditions occur.
INFOVIAL consists of a
web-based traffic management
software system integrating
more than 340 traffic data
sensors plus 70 variable
message signs (VMS)
which communicate
via a 4G cellular
network. The
system collects
real-time data of
traffic conditions
such as speed,
volume, occupancy,
classification of
vehicles and traffic
incidents, and displays
it all on a map at the
Traffic Management Center
(TMC), where conditions are
monitored 24/7. TMC operators
can then apply different strategies
based on the current conditions and
provide the driving public with
alternate routes and information
via the 70 VMS signs which are
installed across the network.
Besides providing real-time data,
INFOVIAL stores the data collected
from the sensors and offers the
agency historical information which
allows the agency to create traffic
studies for the development of
future efficient traffic strategies.
Since its implementation,
INFOVIAL has provided the Public
Works Ministry with the following
benefits:
• Providing an accessible and
reliable database of traffic
conditions from major roads
in Mexico City.
• Allowing the agency to develop
research programs and mobility
studies such as volume, service
levels, occupancy, average speeds,
traffic trends and air quality.
• Analysis and evaluation of
highway traffic conditions, which
can then provide an overview of
traffic behavior.
• Identifying solutions that can help
reduce traffic congestion such as
the implementation of reversible
lanes, updated signal timings,
speed limits and more.
• A source of information for traffic
modeling, allowing the agency
to maximize the capacity of the
existing highway infrastructure.
• Allowing understanding of the
impact in traffic conditions due to
new infrastructure construction
throughout the city.
• Informing drivers in advance
about unexpected traffic
conditions such as public events,
traffic incidents, temporary road
closures and environmental
conditions, and offering
alternate routes.
INFOVIAL’s success is due to
the proper interest in and planning
for better mobility at the Public
Works Ministry in combination
with the software development
and technology integration
achieved by Signal Group.
Ultimately, it’s the result of
Signal Group’s commitment to the
development of intelligent solutions
for better mobility and traffic safety
around the world. ■

City in 2018 – one reason
why it is ranked the worst
city for congestion in
North America
