TWEETY pedestrian touch sound button is suitable for being installed within signalized pedestrian crossings in order to request the green light signal by common pedestrians and blind people according to what provided by Road Code.
The pedestrian button can be used by two kind of users, common pedestrians and blind people.
The request of walk signal made by common pedestrians is sent to the traffic controller so that it can start in the traffic-light cycle the concerned phase and send a feedback used by the device for activating a luminous signal as confirmation of the accepted request.
Used by blind peoplefor requesting the walk signal by a special touch sensitive switch, it offers an immediate response via a sound and vibration confirm ation for all the request duration.
TWEETY offers many operating features thanks to a great flexibility and programming options that makes it suitable to satisfy any specific customer request.
TWEETY push-button is represented by a box containing all of the necessary circuitry. It is generally placed at a standard height from pavement of 1.10-1.20 mt mounted on a traffic pole or wall near the pedestrian crossing.
It offers two types of pedestrian request:
The construction of the button is totally in polycarbonate with an IP55 protection degree, made of adequate and sturdy thickness resistant to normal vandalism.
Control of functionality is entrusted to a microcontroller of adequate capacity that processes and controls the different peripheral elements: it records the request, displays the status of the reservation associated with vibration of the button and / or noise emission, it displays the traffic light status during the course of the cycle on the multicolour backlit graphic display emitting an acoustic signal, if properly reserved, and alternatively emitting a voice message.
The acoustic emission during the associated green phase will be adjusted according to environment noise within the laws on environmental noise abatement.
It is available in three colours: Dark Green (standard), Yellow and Black (on request). It can be adapted and used for other functions within signalized intersections such as for walk requests of bicycles, etc.
