Roadways or Highways

Indian Scenario

“…IT IS NOT WEALTH THAT BUILT THE ROADS BUT,

ROADS THAT BUILT OUR WEALTH”

- John F. Kennedy

LCV and HCV Growth

Vehicle Population Projection

Large Highway Expansion

India is expanding its highway infrastructure by the factor 5.5 in about 7 – 10 years

Large Highway Expansion

Road Length (km)

National Highways / Expressways 70,548

State Highways 1,28,000

Major and Other District Roads 4,70,000

Rural Roads 26,50,000

Total 33,18,548

Large Highway Expansion

An extensive road network (3.3 million kms) – the second largest in the world

Roads carry about 65% of the freight and 85% of the passenger traffic

Highways/Expressways constitute about 2% of all roads and carry 40% of the road traffic

The Government of India spends about Rs.18000 crores (US $ 4 billion) annually on road

Problems

Problems

The irony is approx 1,30,000 people are killed in road crashes every year

Problems

Annual Social costs of road accidents is estimated at Rs.55,000 Crores

3% of the GDP

Problems

Pain, Sorrow & Grief is unaccountable

Problems

Heavily congested

Unabated Violations

Unabated Violations

Unabated Violations

Road Condition

Problems

Mixed Traffic conditions

No provision for segregation

About 85% of all deaths on the roads are pedestrians and cyclists not drivers

Insufficient road capacity

Most of the national highways are two lane or single lane; poorly surfaced; heavily congested; speeds in the range 30-40 kmph

The real issue is

not Car design

but Road design
