🔹 The length of road per 100 sq. km of area is known as density of roads. 

🔹 Distribution of road is not uniform in the country. 

🔹 Density of all roads varies from only 10 km in Jammu & Kashmir to 375 km in Kerala with the national average of 75 km


🔹 Road network is inadequate according to volume of traffic.

🔹 National Highways are inadequate too.

🔹 Half of the roads are unmettaled and this limits their usage during the rainy season.
