Traffic dense visual with A*Star

Hello All,

Is there a way in Flexsim that we can show the traffic by using dense lines like a spaghetti map on the layout.

I guess that is something similar to heat map with A*Sart ,or exist any other that could be measurement?

basically we want to show where we have "dense trafic" after run the model 1 week in order to increase/drecrease the layout..

Thanks

R.V

With the data that can be extracted from A*, drawing lines isn't easily done. The data that can be extracted only gives the amount of time the nodes were allocated. This is how the heat map is generated with the color change surrounding that specific node. Now you could do something else with that data, I attached an example model where all the code can be found on the OnDraw Trigger of the BasicFR1 object to access this data.

So the information you will get from A* is only the hits each node gets from being allocated, not who allocated it. You could try something different with Network nodes and have a counter on each network node of who passed on the node, but there won't be avoidance built in, it will follow predesignated routes.

Hi @Joshua S

I did this model following the "Operator Location" instead A*Star and does exactly what i need, the only issue is that i need to create manually all the variables and all the user event per "Operator", do you know if there is any way to optimize? please see attached, I mean, only ussing one "variablex" one "variabley" and one "UserEvent" for alll of the travelers?
