With the Google Maps API V3 it’s very easy to make the built-in traffic overlay visible.

This is possible with the following code:

var options = {     zoom: myDefaultZoom,     center: new google.maps.LatLng(myLatitude, myLongitude),     mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById('map-container'), options); var trafficLayer = new google.maps.TrafficLayer(); trafficLayer.setMap(map);

Too bad that there is no simple line of code to enable a built-in traffic toggle control (Buttons on the map are called controls). So I created the piece of code More >
