Plain-language change summary

The updated version of House Bill 2134 specifies criteria for 19 counties based on population density and location, which will help identify areas that need regional transportation planning. It also clarifies that if a county falls under two planning organizations, the one with a larger population will take precedence. These changes are important because they aim to ensure that transportation planning is focused on the most populated and rapidly growing areas, ultimately enhancing transportation efficiency and planning consistency across regions.
