IT HAS BEEN A SUCCESS, THE CONCLUSION OF THE EXPERIMENTAL INSTALLATION OF 4 PEDESTRIAN TRAFFIC LIGHT CROSSINGS, EQUIPPED WITH COUNTDOWN AND LANTERNS, GALILEO SERIES, IN THE CITY OF ROME. THIS TEST, AUTHORIZED BY THE MINISTRY OF TRANSPORTATION, WILL ALLOW US TO TRACE A GUIDELINE, THAT WILL RELEASE THE SPECIFICS DEFINITIONS FOR THE PRODUCT APPROVAL. DESCRIPTION OF OPERATION: The countdown CD / PD "pedestrian" is a device designed and developed specifically for the Italian market, for the safety and protection of pedestrians on crossings. As required by the new C.D.S. art. 41, yellow pedestrian has the function to indicate to pedestrians to clear the passage, so the duration of this report, is sized to fit the width of the crossing. Usually the yellow pedestrian signal is misunderstood by pedestrians, which do not know if they can complete the crossing safely, or if they have to walk back. The display of remaining time, becomes essential to pedestrian to ensure the certainty of being able to cross the street safely, therefore particularly suitable for the elderly and vulnerable road users. Used in conjunction with the pedestrian traffic light, the countdown shows with a 2-digit display, the remaining time during the crossing of yellow, on systems regulated by traffic lights. The installation of this device is very simple as it requires a parallel connection to pedestrian yellow, after the countdown shall independently determine, after a traffic light cycle, the time to display. During the first sequence of self-learning, the display shows the yellow segments that run in clockwise rotation, while during any other operation in flashing yellow, the display visualize the flashing of only the horizontal segments. Equipped with an advanced electronics, the countdown is provided of a stability control and signal verification, to the pedestrian cycle, in addition to the monitoring / feedback of the segments (each segment is composed of two branches of LEDs) which provide in ALARM function, in case of burning of the LEDs, and the loss of an entire segment of the display, to the turn off the device. The programming of the countdown can also occur as a video display, through the management through serial port RS232, and the software provided on request. The countdown can be supplied as a single module, inside a polycarbonate optic, ideal to be placed on existing lanterns, without replacing them (after verification of compliance with the legislation) or inserted in the lantern houses such as "Galileo" or "CVE". Thanks to the 125 mm character height, the display provides an excellent viewing up to a distance of 60/70 meters. Maximum displaying time 99 seconds, used as a supplementary module to be installed above the pedestrian lantern or assisted to the yellow.
