Google Maps refresh traffic layer

Question

In my Rails app, the background consists of a fullscreen div with Google Maps and a traffic layer. This is what gets called on page load:

$(function () {  
         


        

Answer 1

A setInterval over the whole initialize routine got me the refreshing that I desired. options.ts_google_map_traffic_refresh_milliseconds is set to the milliseconds you desire.

 setInterval(_ts_map_initialize, options.ts_google_map_traffic_refresh_milliseconds);

    function _ts_map_initialize(){              
        console.log('function _ts_map_initialize()')
        var myLatlng = new google.maps.LatLng(options.ts_google_map_traffic_latHome,options.ts_google_map_traffic_lonHome);
        var myOptions = {
          zoom: ts_int_zoomLevel,
          center: myLatlng,
          panControl: false,              
          zoomControl: false,
          streetViewControl: false,
          overviewMapControl: false,              
          mapTypeId: google.maps.MapTypeId.ROADMAP,
          styles:[{
              featureType:"poi",
              elementType:"labels",
              stylers:[{
                  visibility:"off"
              }]
          }]              
        }
        map = new google.maps.Map(document.getElementById('ts_google_map_traffic_canvas'), myOptions);
        defaultBounds = map.getBounds();

        trafficLayer = new  google.maps.TrafficLayer(); //add the layer - don't view it unless user toggles button  

        trafficLayer.setMap(map);

}
