 Reasons
As cities in the whole world are becoming crowded and the car industry is each time bigger, traffic accidents are increasing, causing real damage to people, social problems and incalculable economic losses.
There are lots of facts that contribute to these losses, and the most relevant is the lack of good signaling.
Many are the countries in the world that are trying to solve this modern problem, but in most of them it is not solved at all but is increasing gradually.
The main objective of this invention is to increase the margin of security to diminish the fatal traffic accidents and its numerous consequences.
Descriptionn
The Electronic, Visual, Numeric and Audible traffic light offers three simultaneous signals of traffic regulation.
- Visual Signal: the three current and conventional colors.
- Numeric Signal: It constantly offers information to pedestrians and drivers about the available time to cross safely the street, or well, to wait patiently for the next free traffic signal in order to cross.
- Audible Signal: A voice, recorded in digital format, announces to pedestrians "Cross", "Don't cross" or "Wait" depending on the signalled light.
Operation
At the beginning of each cycle, the screen shows the corresponding color, like the conventional traffic lights. Simultaneously, the number ten will appear overprinted on it.
While the colour is on, a countdown is working on the overprinted numeration, going by 9, 8, 7, 6, 5, 4, 3, 2 & 1. Lasting each number a tenth of the total time.This time is adjusted automatically in each cycle.
When the color and the numeration appear, a loud voice will be heard, ordering to pedestrians to respect the visual sign present on the traffic light.
Another sign of attention, directed mainly to pedestrians and drivers far from the traffic light, appears when the number 2 appears on the screen and the sign begins to blink, pre-announcing each cycle ending. (in one of eight different modes of operation)
These detailed sequences work when each colour cycle is switched on.
Advantages
-
Funcitonal:
Better security for pedestrians and vehicle drivers: Contrary to the actual LED traffic lights, a LED that fails doesn't annul an entire brunch. Alone that LED is affected.
Available for blind people: A loud voice allows them to determine the correct decision at the beginning of each color cycle.
Full compatible with actual wiring.
It works alternatively like a normal traffic light. (mode 1)
It works alternatively with batteries and solar panels.
-
Economic:
Up to 90 % savings in energy costs.
Up to 90 % savings in maintenance costs.
It can replace two traffic lights in intersections with crossing to the left. (see eight different modes...)
Maintenance-free
-
Expansible:
Its microprocessor based technology opens a wide range of applications where smart control capabilities is needed, examples are:
Infrared beam detection for Police and Ambulance priority.
Light dimming at night, further prolonging the LED life and providing even greater savings on electrical consumption.
Automatic test of each LED in transparent form for the user and communication of the report via serial channel.
Self control and master-slave configuration without need of external controller.
Radio, infrared or power line communication for intersection synchronization without need of external control wiring. Only one power line is required.
Conclusions
The best service, the better quality and less expenses will be the most relevant factors for the adoption of this invention in the technology improvement era and special attention to the economic budget.
Pressing the button in the back of the optic unit, five different operation modes are selected
When the button is pressed an upward count from 1 to 5 is shown, loosing it, the mode is programmed.
Modes of operation
- 1 full screen
- 2 countdown from 10 o 1 without flash
- 3 countdown from 10 o 1 without flash
- 4 countdown from 10 o 0 without flash
- 5 countdown from 10 o 0 with flash
Nota: Flasheo significa que el digito comienza a titilar a patir del numero 2 hacia
