That's false. The mistake universally made by people repeating that claim is a failure to account for the fact that vehicles and population are finite. In the US there isn't much population growth, except for in a select few urban areas. It's baffling that it gets repeated so often as though it's always true, when it's not. You can swamp the amount of induced demand with additional roads, it all depends on the number of vehicles you're dealing with. Which is to say, it depends on context and it's incorrect to suggest matter-of-fact that induced demand defeats additional roads.
You'd need to run a study on the traffic potential and local + regional population growth to know one way or another what additional roads might do as it pertains to inducing demand over time and whether you can overcome the expected increased demand. The demand doesn't just keep rising forever as you build more roads.
