Based　on　the　digital　hormone　model,　this　paper　established　a　new　distributed　coordination　control　scheme　for　traffic　signals,　which　adopts　some　hormonal　information.　The　experiments　with　a　traffic　network　of　8　junctions　shows　that　this　new　control　method　is　obviously　superior　to　the　timing　control,　sensing　control　and　real-time　control.　©　2010　IEEE.
