Abstract:

This paper study stops at signalized intersection using macroscopic traffic model. Through the analysis the startwave and stop  wave in front of the stop line, it is concluded that the absolutely onestop condition don't exist. And the relationship between accumulatedischarge mode and stop ratio is researched. Trajectory of vehicles is classed according to the stable condition and the stop ratio is studied. The designed numerical example shows that stop ratio model based on Stable Theory is always over estimate the stop ratio, and the bigger the saturation is, the bigger the result is overestimated. The reason is that it adopts the point queue assumption.

Key words: engineering of communications and transportation, stops, traffic wave, vehicle queue, signal control
