Electronic information technology in intelligence street-traffic control lights control application1 IntroductionThe urbanized advancement speeds up day by day with automobiles day-by-day popularization, the accident frequency sends, the traffic congestion to intensify, the state of roads to worsen day by day, the transportation question already became the puzzle world the serious problem. From this causes traffic order worsened already serious influence modernization urban construction and national economy development. Studies vehicles general rule, to alleviates the traffic jam according to the actual situation formulation corresponding general rule, raises the street intersection vehicles general efficiency to have the very vital practical significance. The street-traffic control lights are managing the transport network the most important element, but street various street intersections are also the vehicles general key are. Along with the electronic information technologys rapid development, its related hypothesized instrument technology in the data acquisition, the test automation and the instrument control domain obtains the widespread application, caused the test system and the survey control design method with realizes the technology to have the deep transformation. “the software was the instrument” already became the test and the measuring technique development important symbol. 2 Based on electronic information technology hypothesized instrument technological development and applied analysis Based on the electronic information technologys hypothesized instrument technology is one in new century science and technology core technologies, it contained the computer technology, the automatic control technology, the information technology, the electronic technology and so on to be various. The American Country Instrument Company in the mid-1980s first proposed that based on computer technologys hypothesized instruments concept, leads the hypothesized test tech
