AbstractWith the development of modern traffic, traffic signal transmission plays an important role in traffic operation in modern traffic management, LED alterable sign is the main information release equipment. In the test process of LED alterable sign, the chromaticity coordinate is an important property of LED alterable sign. A determination software was developed for chromaticity coordinate of LED alterable sign and LED lane indicator aimed at LED alterable sign of the decision problem, which could quickly and accurately determine whether the test data conform to the standards, improved the working speed of electrical and mechanical testing and reduce misjudgment.
