most used route by vehicle history

[MRReddy]

Hi

I have history of some x number of vehicles, like which route it travelled(data in polyline format)

I'm trying to figure out how to calculate/find most used route by these vehicles.

I do know about heat map, but I'm interested to find particular most used route's by vehicles.

Is there any way to calculate, Any suggestions please

Thanks
