I think a bit more information on the data you have would help? Do you have the locations of the cars, or just a number of cars at an intersection, or a number of cars on any road leading into the intersection? Are you only every talking a couple of cars, or up to hundreds... Are your roads stored as lines, or are you just working with points?
I guess I'm saying there are many ways to skin a cat, but it does help to know what a cat looks like first! cheers Ben On 01/10/2011, at 12:00 AM, [email protected] wrote: > From: knasia <[email protected]> > Date: 29 September 2011 4:03:34 PM AWST > To: [email protected] > Subject: [mapserver-users] traffic queues visualization > > > hi, > I have to visualize traffic queues at the crossroads.
