Explanation:

• They gave more stress on future planning programs, for a period of 20 years (hence called a twenty-year plan) that's to formulate plans and implement those plans within the next 20 years.

• One of the recommendations was the holding of periodic road conferences to DEBATE about construction and development. This lead the way for the establishment of a semi-official technical body called Indian Road Congress (IRC) in 1934

• They suggested the imposition of additional taxation on motor transport which incorporates duty on motor spirit, vehicle taxation, license fees for VEHICLES plying for hire. This paved the way to the introduction of a development fund called the Central road fund in 1929. This fund was intended for road development.

• A dedicated research organization should be constituted to hold out research and development work. This resulted in the formation of the Central Road Research Institute (CRRI) in 1950.
