How to show travel DIRECTION ARROW in Google Map Javascript API when using POLY LINE?
You may calculate the angle between two points, here's a how-to.
Depending on the calculated angle you can place a marker at the start-point. Here you find the description of the markers: http://sites.google.com/site/gmapicons/home/ (Direction indicators)
Edit:
See a demo: http://jsfiddle.net/doktormolle/9gJjj/
You'll find a function fx()
there which expects a DirectionsRoute as argument and draws the markers.
Edit2:
Note that you may also use an IconSequence which may be a better approach, See: Google Map API Direction Triangle Icon Ambiguous
