Kerala has 145,704 km of roads (4.2% of India’s total). This translates into about 4.62 km of road per thousand population, compared to an all-India average of 2.59 km. Virtually all of Kerala’s villages are connected by road. Traffic in Kerala has been growing at a rate of 10-11% every year, resulting in high traffic and pressure on the roads. Total road length in Kerala increased by 5% between 2003-2004. The road density in Kerala is nearly four times the national average, and is a reflection of Kerala’s unique settlement patterns. India’s national highway network includes a Kerala-wide total of 1,524 km, which is only 2.6% of the national total. There are eight designated national highways in the state. Upgrading and maintenance of 1,600 km of state highways and major district roads have been taken up under the Kerala State Transport Project (KSTP), which includes the GIS-based Road Information and Management Project (RIMS).
