Aimed at the disadvantage of time reconstruction formula of discrete periodic signals, a new formula with the help of Discrete Fourier Transforms (DFT) is obtained.

Study on a new method for high-speed data acquisition of periodic signal;

Waveform design and spectral analysis in direct digital synthesizing of periodic signals;

Study on sampling non-synchronism for periodic signal;

According to the queue length waiting in each intersection,both the signal cycle and the split of every intersection were given out.

A method of computing the signal cycle for the coordinated signal control scheme is i.

The queuing states in the green end were taken as objective,the dynamic signal timing at single-point intersection under the control of two-phase signal was studied,a queuing model was built according to the queuing and discharging process,and the effects of signal cycle,split and arrival ratio on the queuing states were analysed.

Reconstruction of periodic signals based on non-uniformity synchronous sampling;

Application of genetic algorithm in Fourier transform of periodic signals;

Detection methods research of frequency domain based on periodic signals;

This paper analyzes the factors which affect the capacity and level of service of the single signalized intersection , reveals the pattern how the capacity and delay change with the changes of the cycle , draw a reasonable extend of a optimum cycle , put forward the traffic management measures when the intersection is saturated or oversaturated .
