i have got issue about traffic map with using openlayers library.

Traffic layer shifting from sublayer. so roads and streets are mismatch. can you help me please.

in jsfiddle

The code from the jsfiddle is as follows: http://jsfiddle.net/L4qubkhd/.

enter image description here

var projection1 = new OpenLayers.Projection('EPSG:4326');
var displayProjection1 = new OpenLayers.Projection('EPSG:900913');
var centerLat = 55.75;
var centerLon = 37.62;  

function yandex_getTileURL(bounds) {
    var r = this.map.getResolution();
    var maxExt = (this.maxExtent) ? this.maxExtent : YaBounds;
    var w = (this.tileSize) ? this.tileSize.w : 256;
    var h = (this.tileSize) ? this.tileSize.h : 256;
    var x = Math.round((bounds.left - maxExt.left)/(r * w));
    var y = Math.round((maxExt.top - bounds.top)/(r * h));
    var z = this.map.getZoom();
    var lim = Math.pow(2, z);
    if (y <0>= lim) {
        return OpenLayers.Util.getImagesLocation() + "404.png";
    } else {
        x = ((x % lim) + lim) % lim;

        var url = (this.url) ? this.url : "http://vec02.maps.yandex.net/";
        //console.log("http://vec0"+((x+y)%5)+".maps.yandex.net/tiles?l=map&v=2.16.0&x=" +x + "&y=" + y + "&z=" + z + "");
        return "http://vec02.maps.yandex.net/tiles?l=map&v=2.16.0&x=" +x + "&y=" + y + "&z=" + z + "";

       // return url + "tiles?l=map&v=2.2.3&x=" + x + "&y=" + y + "&z=" + z;
    }
};
function yandex_traffic_getTileURL(bounds) {
    var r = this.map.getResolution();
    var maxExt = (this.maxExtent) ? this.maxExtent : YaBounds;
    var w = (this.tileSize) ? this.tileSize.w : 256;
    var h = (this.tileSize) ? this.tileSize.h : 256;
    var x = Math.round((bounds.left - maxExt.left)/(r * w));
    var y = Math.round((maxExt.top - bounds.top)/(r * h));
    var z = this.map.getZoom();
    var lim = Math.pow(2, z);
    if (y <0>= lim) {
        return OpenLayers.Util.getImagesLocation() + "404.png";
    } else {
        x = ((x % lim) + lim) % lim;
        var url = (this.url) ? this.url : "http://jgo.maps.yandex.net/1.1/"; 
    return  url + "tiles?l=trf,trfe,trfl&lang=tr_TR&z=" + z + "&x=" + x + "&y=" + y + "&tm=1445001388";
    }
};

  • Did you consider just using the Yandex JavaScript API – nmtoken Mar 4 '17 at 11:05

Yandex uses different projection than Google Maps or OSM. You may find this post useful: https://habrahabr.ru/post/151103/ though it is in Russian and for Android Java (to add yandex maps layer to osmdroid project).

I hope you can use math from there, or try to google for the same math for OpenLayers.
