  • Automated traffic signal controller with remote accessibility 
    Jayasinghe, JAKS; Arachchi, HK [Conference-Full-text]
    Development of the hardware, firmware and control and monitoring software to interface the UNIROAD Traffic Signal Controller (TSC) to Advanced Traffic Control System (ATCS) is described. This system is capable of controlling ...
  • A CCTV image grabber for vehicular parameter detection. 
    Jayasinghe, JAKS; Nishantha, GGD [Conference-Full-text]
    The concept of vision information has become a key feature in moden vehicular traffic control and Intelligent Vehicle Highway Systems (IVHS) [1]. Vehicle detection by video cameras is one of the most promising new technologies ...
  • Design of a low noise pre amplifier for terrestrial television reception 
    Jayasinghe, JAKS [Conference-Full-text]
    Low Noise Pre-amplifiers (LNP) increase the quality of weak signals by amplifying them without introducing excessive noise generated inside the amplifier. The advantage of using LNP for weak TV signal reception is presented ...
  • Lamp driver & failure detector for incandescent lamps in traffic signal systems 
    Jayasinghe, JAKS; Ranaweera, RAKP [Conference-Full-text]
    The design and implementation of a low cost solid-state lamp driver and failure detector (LD/FD) for incandescent lamps is described. The design is directly targeted for the signal lamp heads in highway traffic signal ...
  • Multiprocessor architecture for adaptive control of traffic light systems 
    Jayasinghe, JAKS [Conference-Full-text]
    Construction of new highways or expansion of existing highways to meet the ever- increasing highway traffic is a very expensive and time-consuming task. Management of existing highways effectively is considered as a high ...
