Where is a good place to do drive cycles to get the OBD2 parameters in the ready state for an emissions test?

I’m still checking which drive cycle patterns I need to run, but most of them involve driving at steady speeds for several minutes. I saw prescribed patterns like driving about 30 mph for 2 or 3 min, and driving about 40-60 mph for 10-15 minutes. I might have to drive longer to set some parameters in ready state, but I guess a 12-15 mile flat stretch where you don’t have to brake, turn, or accelerate will work for most cars. I’m thinking I-64 might work, hugging the right lanes at 55-60 mph during low traffic for the faster pattern. Then for the slower pattern, maybe use Lindberg or some frontage road?

Who here has done similar drive cycles to prep older cars for emissions testing and can recommend good stretches of road for a couple different speed ranges?

Thanks for your suggestions.

    Thanks. I hope it’s that easy, but apparently there are many potential complications, and aging cars/parts can make it harder to eval the monitors properly. Some cars have very specific drive cycles and different patterns for the different monitors. Sometimes the tests don’t all get triggered in “mixed driving”, but I’ll give it a try and see if it still needs something more specific.
