Background
A range of products designed to aid network managers optimise the efficiency
of the existing network and extend the operational life of the road.
Traffic movement, contra-flow and tidal-flow lane management, driver
safety, data collection, incident detection, hazard warning and speed
limit enforcement are all achievable within the Reflecto Traffic Guidance
System. Provision of traffic guidance at road level offers significant
safety advantages to drivers when compared to systems placed at the
roadside or on overhead gantries.

Functionality
Each system is built to meet customer's exact requirements. Reflecto
are able to offer advice and guidance based on each individual location.
Each system may be manually controlled, programmed to operate autonomously
or simply operated as a slave, linked to existing traffic control systems.
Guidance
Through the use of system activation, colour selection, and display
modes, traffic may be directed along a specific route. In its simplest
format, TGS may be operated within Toll Plazas to illustrate active
lanes. Similar operation would apply for airport taxi-ways. Marshalling
of vehicle movements, embarking/disembarking of ferry and train traffic
is also greatly simplified through the use of TGS.
Contra-flow and tidal flow signalling is also achieved using TGS and
can be linked to overhead gantries in addition to operating autonomously
for example on a timed programme.
Safety
Driver awareness of prohibitory lane marking and therefore vehicle separation
is enhanced through the use of TGS.
Full visibility is maintained throughout all lighting conditions. Increased
conspicuity is also possible through the use of flash sequences.
Display settings can be used to influence driver behaviour. A running
strobe light perceived to be running toward the driver, or perceived
to be running ahead, but slower than the driver, can positively influence
drivers to adjust speed. Linked to intersection controllers, TGS reinforces
traffic control signals and helps drivers to recognize the need to stop
in good time, and reducing last minute braking.
TGS is applied to cross walk systems to heighten driver awareness that
a pedestrian has stepped out, or is about to step out onto the carriageway.
Invisible to the pedestrian, TGS does not replace the 'WALK' / DON'T
WALK interaction of traditional controllers.
Hazard and incident detection
A range of hazards from surface water, ice and fog can be detected and
communicated either to driver, emergency vehicles or Highway Control
Centres. Incident detection, for example queuing traffic, stationary
vehicles on the hard shoulder can also be responded to and monitored.
Detection by existing equipment may also be used to communicate the
hazard ahead, extending the signal for hundreds of metres back along
the highway.
Informed divers adjust approach speed and if necessary take alternative
routes.
The range of applications and combinations of functionality is almost
endless.
