If you don't want them to flicker, don't "remove" them from the map, update their position.

var map;
var marker;
var markerarray =[];

setInterval(function(){
  $.ajax({
    type: "post",
    url: "vehiclecordinates.php",
    success: function(data){
      coordinates = data.latlng;
      vehiclename = data.vehiclename;
      for (var i = 0; i < coordinates.length; i++) {
        newcoordinate = new google.maps.LatLng(coordinates[i].split(",")[0],coordinates[i].split(",")[1]);
        if (markerarray[vehiclename[i]] && markerarray[vehiclename[i]].setPosition){
          markerarray[vehiclename[i]].setPosition(newcoordinate);
        else {
          marker =  new MarkerWithLabel({
            map:map,
            labelClass: "mylabels",
            labelStyle: {opacity: 1.0},
            labelContent: '<div>'+ vehiclename[i]+'</div>',
            icon:{
              //some options here
            }
          });
          marker.setPosition(newcoordinate);
          markerarray[vehiclename[i]] = marker;
        }
      }
    }
  });
},5000);
