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.
Indeed, many of the functions of the Reflecto Traffic Guidance System could not be achieved in any other format.

Traffic Guidance Systems (TGS) are based upon the highly successful Reflectolite housing. Specially developed circuitry and a mains/solar option power supply offer increased functionality over the solar powered Reflectolite system.

High intensity LED display enables 24-hour operation in all weather conditions and providing a clearly visible signal even under strong sunlight. A hardwired power supply enables higher levels of performance in addition to a robust, secure method of communication between each stud. Power is supplied via mains or local solar input.
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.
