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
Dr. P. Nanjundaswamy SJCE Mysore 5
Modes of Transportation
Primary Modes
Roadways
Railways
Surface, Elevated, Underground (Tube), Light Rail Transit
Airways
Waterways
International Shipping, Inland water transport
Dr. P. Nanjundaswamy SJCE Mysore 6
Modes of Transportation . . . .
Secondary Modes
Pipe lines
Elevators
Belt conveyors
Cable cars
Ropeways
monorails
Dr. P. Nanjundaswamy SJCE Mysore 7
Characteristics of Transport modes
Airways
Fastest, more comfort
Waterways
Slowest
Minimum energy
Railways
Energy requirement (1/4 to 1/6 – by road)
Dr. P. Nanjundaswamy SJCE Mysore 8
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

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)
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

Large Highway Expansion
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
Dr. P. Nanjundaswamy SJCE Mysore 19
Problems
Indian roads the most dangerous in the world
Dr. P. Nanjundaswamy SJCE Mysore 20
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
Dr. P. Nanjundaswamy SJCE Mysore 21
Problems . . . .
Annual Social costs of road accidents is estimated at Rs.60,000 Crores
3% of the GDP
Dr. P. Nanjundaswamy SJCE Mysore 22
Problems . . . .
Pain, Sorrow & Grief is unaccountable
Dr. P. Nanjundaswamy SJCE Mysore 23
Problems . . . .
Heavily congested

Is this representing India?
Dr. P. Nanjundaswamy SJCE Mysore 32
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
Dr. P. Nanjundaswamy SJCE Mysore 33
The real issue is
Not Vehicle design
But Road and Road User
