摘要
Abstract
This paper studies the traffic state transition and puts forward a new method of judging traffic state change time, the x-t curve, based on the traditional traffic state model, and compares it with the traffic flow parameter adjustment accumulative curve to prove its effectiveness and accuracy. This method improves the accuracy of judging the state transition time in the traffic congestion, and can be very useful in the research on traffic flow.关键词
