Dynamically combined and separated of sub-zone in adaptive traffic signal control area

This paper analyzes the influence factors of sub-zone combined and separated in adaptive traffic signal control system and attempts to fix quantify influence factors that act as the performance indices. Then analyzes the intersections correlation coefficient confirms the ideal state and negative state of sub-zonepsilas combined and separated. Collect VISSIM data as datum mark to compute adjacent intersectionpsilas hamming osculating, coefficient and dynamic cluster analysis.
