The purpose of this legislation, known as the Transportation Asset Management Simplification Act, is to enhance the management of transportation assets across the United States. It aims to streamline the process by which states develop and maintain their transportation asset management plans, ensuring that these plans are effective and up to date. Key provisions of the legislation include changes to how often states must update their asset management plans. Instead of requiring updates every fiscal year, states will now only need to update their plans once every four years.
