1.3. Introduction
The Sphere ST-PS5 Portable Traffic Signals is a modular mobile traffic signal system intended to be applied primarily to shuttle
the control of vehicular traffic at road works or bridge works.
Road works where Portable Traffic Signals are applied have a a section of the carriage-way closed, so the single lane must be
used alternatively by traffic from the opposite directions.
Other than vehicle-actuated alternating one-way traffic, the ST-PS5 can also be used for controlling the T-junction situations,
crossroads traffic and roundabouts, with up to 7 signals operating simultaneuosly in a Daisy Chain operational mode.
The ST-PS5 Portable Traffic Signals are equipped with a directional radar for vehicle-actuated operation, radio communication
with a range of up to 1000 m under ideal conditions and emergency mode for quartz control when the radio communication
is faulty.
