Thermal　environments　significantly　influence　the　sensation　of　pedestrians.　This　work　proposes　a　navigational　approach　that　takes　into　consideration　the　perception　of　comfort　by　a　pedestrian.　Air　temperature,　relative　humidity　and　wind　velocity　are　the　main　factors　that　influence　human　sensation　of　thermal,6　sensors　have　been　place　in　our　study　area　in　order　to　collect　sensor　data　of　above　factors.　We　use　Universal　Thermal　Climate　Index,　which　is　the　most　advanced　multi-node　model　of　thermoregulations　to　help　assess　comfortable　level　of　each　path.　Finally,　a　comfort-based　navigation　approach　was　discussed.　©　2018　IEEE.
