Google Maps - Follow Path Of Travel

I am working with a security company that has a patrol car travel around a neighborhood. Every 30 seconds, they record a GPS coordinate/point which I can download and use. I'm trying to map a 'path of travel' for the patrol vehicle using Google Maps API.

I understand how to map (marker) all the points using the Google Maps v3 API. I also understand how I can do a driving route between a few points using directionsService. According to Google and StackOverflow, the maximum number of waypoints is 26.

The problem is that I have dozens of these points (1 hour = 120 points). I can't just draw a polyline between the points because I need it to show the path of travel on the actual street - not as the crow flies between 2 points. Also, I don't have 10K to purchase an Enterprise license.

Any ideas on how this might be accomplished or am I SOL? Can you draw 120 multiple 'routes' on the same map? Speed is not important here.

Thanks, Mike

You can. When you want to draw the routes by using the DirectionsRenderer you must use a separate DirectionsRenderer-instance for each route.

Another approach: request the routes via the DirectionsService, but use a custom Polyline to draw the route. Each time you get a new route you'll only have to push the points of the new route to the path of the polyline.
