Abstract—Reasonable timing design for traf¿c light can induce transportation policy are expressed in language, so how to deal
and maintain the transportation systems in good order. How with perception information es one of the keys to solve
to allocate the time are the keys. In the paper, the theory of these problems. Linguistic dynamic systems(LDS) is based on
time-varying universe is used to describe the circle time, and
corresponding fuzzy sets on the universe are also discussed puting with words instead of numbers and symbols, and
modeling the situation of traf¿c Àow, then the parallel traf¿c the problems of modeling, analysis, evaluation and control for
management and control methods which are dynamic with plex systems can b
