The last Google bypass revealed the Open Source Projects section for me.
code.google.com/hosting/projects.html?filter=1&start=0My attention stopped on a page dedicated to the Google Maps API Utility Library
code.google.com/p/gmaps-utility-libraryThis page provides examples of various library releases related to the Google Maps API.
For those who do not have an API reference, as well as people who just decide to get acquainted with the possibilities, the page will be useful. On it you will find examples of implementations of custom markers, interactions with them. Considered the implementation of AJAX with respect to them.

Everyone knows that the examples are easier to understand. This is exactly this option. But do not forget about the main section on Google maps
code.google.com/apis/mapsThe page says that it is an open source project. Designed as a repository of useful libraries for use with Google maps
Special attention should be paid to
gmaps-utility-library.googlecode.com/svn/trunk/extmaptypecontrol/1.3/examples/trafficexample.htmlA good interactive example to get an idea of the possibilities.
I forgot to say that there the source code of the examples is attached to all libraries.
