Hi

You can add overlay to the map by adding 'overlay' sections into your macro in 'Build a GMap macro'. You can use kml files like this which using Google Earth. Instruction is in: modules\gmap_addons\gmap_overlays\README.txt

I builded macro with line 'overlay=kml:http://mapgadgets.googlepages.com/cta.kml ' for tests:

[gmap overlay=kml:http://mapgadgets.googlepages.com/cta.kml |markers=small red::41.840408844786396,-87.71209716796875 |zoom=9 |center=41.887965758804484,-87.81646728515625 |width=700px |height=500px |control=Small |type=Physical]

but something is wrong because I get warning and overlay don't display:

warning: Invalid argument supplied for foreach() in C:\...\drupal-6.16\modules\gmap_addons\gmap_overlays\gmap_overlays.module on line 46.

I tried to open 'http://mapgadgets.googlepages.com/cta.kml' file in Google Earth and it work, so I think something is bad with 'gmap_overlays' module.

I'm using:
PHP 5.3.1
Drupal 6.16
gmap-6.x-1.1-rc1 with some patches for PHP 5.3.1

Sorry for my English.

I've added traffic to the map. I know this thread is a bit old but it might save someone time in the future:

In a javascript file (traffic-overlay.js):

(function($) {
  // just to make sure everything is loaded properly
  if(($('#map_id')) && (Drupal.gmap)) {
    Drupal.gmap.addHandler('gmap', function (elem) {
      var obj = this;

      obj.bind('init', function () {
        var trafficOptions = {incidents:true};
        trafficInfo = new GTrafficOverlay(trafficOptions);
        obj.map.addOverlay(trafficInfo);

      });
    });
  }
})(jQuery);

Then:

<?php
// scope ensures that the gmap object is properly loaded before this code gets called
drupal_add_js('/path/to/js/traffic-overlay.js',array('scope'=>'footer'));
?>
nobody click here
