Role of Transportation in Society

Transportation

is a non separable part of any society

is responsible for the development of civilizations

meets travel requirement of people and transport requirement of goods

is one of the key infrastructures of a country & considered a mark of its progress

Role of Transportation in Society . . . .

Summary

Advancement of community

Economic prosperity and general development of a country

Strategic movement in emergency

Safety, Pollution, Energy consumption

Other impacts

Modes of Transportation

Primary Modes

Roadways

Railways

Surface, Elevated, Underground (Tube), Light Rail Transit

Airways

Waterways

International Shipping, Inland water transport

Modes of Transportation . . . .

Secondary Modes

Pipe lines

Elevators

Belt conveyors

Cable cars

Ropeways

monorails

Characteristics of Transport modes

Airways

Fastest, more comfort

Waterways

Slowest

Minimum energy

Railways

Energy requirement (1/4 to 1/6 – by road)

Roadways or Highways

Maximum flexibility for travel

Route, Direction, Time and Speed

χ Safety decreases

Door to door service

Feeder system for other modes

Used by various types of vehicles

For short distance travel – saves time

Requires relatively small investment

Characteristics of Transport modes

Roadways or Highways

Indian Scenario

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

ROADS THAT BUILT OUR WEALTH”

- John F. Kennedy

Vehicle Population Projection

Large Highway Expansion

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

NHDPBiggest initiative7 phases2,35,690 crores till 2015

SARDP-NE9760 km improvement

PMGSY Phase I & II

In 2 phases

Target :

2414+ 3411 km

Road Length (km)

Expressways 2,000

National Highways 92,851

State Highways 1,63,898

Major and Other District Roads 17,05,706

Rural Roads and other Roads 27,49,805

Total 47,14,260

MORTH targets laying over 40 km of roads every day in 2016-17

Source NHAI 2016

An extensive road network (4.7 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. 25,000 crores (US $ 4 billion) annually on road

Problems

Indian roads the most dangerous in the world

Problems . . . .

The irony is 1.46 Lakh persons are killed and 5.0 Lakh people are injured in road crashes during 2015-16

40% of the Deaths

Problems . . . .

Annual Social costs of road accidents is estimated at Rs.60,000 Crores

3% of the GDP

Problems . . . .

Pain, Sorrow & Grief is unaccountable

Problems . . . .

Heavily congested

Accidents : 2005 – 2015

Source MORTH 2016

Leading Causes of Death & Disability

Unabated Violations

Road Condition

Is this representing India?

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 Vehicle design

But Road and Road User

CV 530 – Highway Engineering
