The first serious attempt to develop modern road transport is known as ______.

Nagpur plan

The correct answer is Option (1) → Nagpur plan

Road transport in modern sense was very limited in India before World War-II. The first serious attempt was made in 1943 when ‘Nagpur Plan’ was drawn. This plan could not be implemented due to lack of coordination among the princely states and British India. After Independence, twenty-year road plan (1961) was introduced to improve the conditions of roads in India.
