TRAFFIC CONTROL |
Holistic solutions to
city traffic problems
Solving city mobility cannot be achieved by controlling single
intersections – a contextual approach is required. Understanding
a city’s variety of needs, with sustainable mobility at its core, forms
the cornerstone of Cross Zlín’s approach to urban traffic control

solutions, ranging from product
manufacturing to installation with
subsequent operation and servicing.
Its products, namely the RS range
of traffic light controllers and the
universal RSU (Roadside Unit),
already utilise C2X protocols.
Historically, C2X was used for public
transport preference, enabling the
faster and smoother passage of
buses or trams through a city.
Data is sent from the vehicle
to the controller, who then decides
to prioritise the vehicle passage

based on city’s traffic policy,
for instance delaying or giving
absolute priority. On past projects
with public transport priority, Cross
Zlín managed to cut public vehicle
travel times by 15%. Such systems can
be supplemented with bus/tram stop
passenger information displays that
show line information: expected
arrivals or delays.
These systems can also inform
drivers by showing travel times,
warning about congestion or helping
to navigate to vacant parking areas.
Existing city technologies can be
equipped with C2X-enabled end
points, the RSUs, thus enabling direct
communication with drivers without
significant CAPEX requirements.
Adaptive control
The passenger car expansion that has
taken place in recent years is making
it increasingly difficult to keep traffic
flowing through our cities. This is
especially true in peak hours, with
intersections approaching saturation
levels and resulting in congestion.
Cross Zlín’s contribution to solving
these challenges is a continuous
development of novel control
strategies that react to traffic
demand in real time.
Cross Zlín’s adaptive control
system gathers detector data and
automatically calculates the optimal
signal timing for the upcoming cycle.
