For　decades　traffic　control　in　road　networks　around　the　world　has　been　successfully　managed　by　the　use　of　traffic　signals.　Applied　design　methods　and　parameters　to　signalise　intersections　are　quite　similar　in　European　as　well　as　Asian　countries.　But　in　some　cases　there　are　some　basic　differences　in　the　design　which　could　have　a　significant　influence　for　instance　on　＇quality　of　traffic　flow＇　and　especially　on　＇road　traffic　safety＇.　This　paper　gives　a　descriptive　overview　and　makes　a　comparison　of　some　selected　methods　and　parameters　applied　in　Germany,　Thailand　and　China　in　the　design　of　signalised　intersections　and　here　especially　in　the　design　of　signal　programs.　Based　on　a　comparison　study　the　authors　make　some　recommendations　for　the　application　of　investigated　methods　and　parameters　in　the　three　countries.　On　this　basis　the　reader　of　the　paper　can　share　experiences　made　by　the　experts.
