Malaysia Uni creates single-display traffic light

Researchers at the Universiti Teknikal Malaysia Melaka (UTeM) have created what they claim is the world’s first traffic light that uses a single display, but plays the same role, or even better compared to traditional three display sets. The multi-colour display is a low-power unit (6-12V DC) that costs significantly less to manufacture (split board, fewer LEDs, small PCB boards, and a common board for all three colours) and maintain and requires only two output controllers to display the three different co

Researchers at the 5998 Universiti Teknikal Malaysia Melaka (UTeM) have created what they claim is the world’s first traffic light that uses a single display, but plays the same role, or even better compared to traditional three display sets. The multi-colour display is a low-power unit (6-12V DC) that costs significantly less to manufacture (split board, fewer LEDs, small PCB boards, and a common board for all three colours) and maintain and requires only two output controllers to display the three different colours. Importantly, the colour-blind have been catered for through the use of different symbols to indicate the change in light colours.

According to the researchers, the system can be integrated easily into existing traffic light systems, regardless of control type and cabling. Voltage and existing cabling methods can be modified to be compatible with the single-display traffic light system.

    Collection of traffic and transit data has grown significantly, combining with advances in connectivity and computational modelling to good effect. Desire to do more with less – to make budgets go further – has helped create a boom in the collection and study of traffic and transport data. Studies are becoming longer, greater in number and further in-depth as more intelligence is sought, plus, transportation agencies are looking to make processes of data collection less costly, or more efficient.

    Beginning in the first quarter of 2010 it became evident that the IntelliDrivesm programme direction had been reestablished, by the USDOT's ITS Joint Program Office (JPO), after being adrift for a few years. The programme was now moving toward a deployment future and with a much broader stakeholder involvement than it had exhibited previously. By today not only is it evident that the programme was reestablished with a renewed emphasis on deployment, it is also apparent that it is moving along at a faster pa
