How to simulate route with driving directions. driving direction should be speak turn by turn like real gps navigator application. I have set of driving directions and i want to speak it on each driving direction reached. i am doing like below. here distance is the distance between last gps possition to current gps possition . and dd is the variable for driving direction which will be increase on each driving direction reached.

var tempP; var xy = DrivingDirectionGeomatry.XY[dd]; if (DrivingDirectionGeomatry != undefined) var length = dojo.number.format(DrivingDirectionGeomatry.Attributes[dd].length) var point = new esri.geometry.Point({ "x": xy[0], "y": xy[1], "spatialReference": { " wkid": appLayers.map.spatialReference } }); tempP = point; var d = dojo.number.format(distance); var remDistance = dojo.number.format(length - d); if (remDistance < 0) { return; } if ((remDistance <= 100 && remDistance > 0 || remDistance == length) && DrivingDirectionGeomatry.IsTraval[dd] == false) { txtToSpeech.Speak(DrivingDirectionGeomatry.Attributes[dd].text, TextToSpeech.SpeechRate.VeryLow, TextToSpeech.PitchRate.Normal); DrivingDirectionGeomatry.IsTraval[dd] = true; lastPossition.lat = null; lastPossition.lon = null; currentPossition.distance = null; dd++; }
