Going ever further
Since the dawn of time, humans have searched for ways to explore and conquer. Is this the source of their misfortunes ? Indeed ! asserts Blaise Pascal, a famous 17th century philosopher « Man doesn't know how to stay at peace in a room ». Yet, transportation is synonymous with great liberty. It plays a fundamental role.
Road to hell ?Immense costs derive from road transportation, in terms of health, loss of time, climate change and nature degradation. How can we reduce this impact? |
Enabling the movement of goods, finances, energy, information, tourists…, it brings men together. Source of progress and of great technical innovations, means of transportation shape our societies, thus drastically changing our ways of life, our landscape and even our climate. Paradoxically, over the past 30 years and more, time spent travelling has kept a constant rate estimated at 1,1 hour per person and per day worldwide. A fact that hides profound disparities. Rich and poor countries don't move at the same pace. While 80% of the people don't have a car and travel by bicycle, by bus, by cart or on foot, the number of vehicles on the road today has reached a triumphant 700 millions, ten times more than in 1950. Cars alone represent 53% of global mobility, far ahead buses (29%), trains (9%) and high speed means of transportation (plane, high-speed trains, 9%). The road supremacy is complete : it represents 82 % of global mobility.
Local pollution and greenhouse effect
What will happen when every single person on earth will have their own car ? Carbon monoxide, Nitrogen oxide and Hydrocarbons emissions from cars already account for 80% of air pollution. The hidden costs are immense : locally, these

gases alter health, buildings and nature. Numerous cities are asphyxiated by car exhausts. According to the World Health Organisation, this pollution causes 500,000 deaths and an additional 4.5 million cases of chronic bronchitis every year, without even mentioning costs associated to car crashes, noise pollution, traffic jams and division of natural spaces. On a global level now, scientists warn that the accumulation of greenhouse gases play a role in climate change. Transportation does not only raises problems in terms of air pollution. Depletion of energy resources is also in question. The amount of oil consumed by means of transportation keeps on increasing every four years, while the reserves of this non-renewable fossil fuel is running out.
Economic distortions
In fact, the price that one pay for a car doesn't include numerous costs that are finally paid by society in terms of health, time, space, climate change, and impact on nature... Yet, altogether, such costs can represent up to 5% of the gross national product of an industrial country. The best way to manage this economic distortion would be to apply the polluter pay principle. The public interests are obvious, but private ones (individuals or companies) are such that it is difficult to lower the car supremacy. Yet, solutions exist. Some cities already took measures in that direction. London, for example, established an 8 euros toll for every car entering the city centre. A world initiative which is considered to be a good answer to traffic congestion and air pollution. The aim in the long run is to reduce car traffic by 5 to 10% to encourage public transportation. As a comparison, 1 tramway or 3 buses can substitute to 200 cars. But this is not enough : to be attractive, public transport networks must serve towns, regions and countries with efficiency, safety and comfort. Truck transportation by train (« rolling highways »), carpooling systems, or home-based work are other possible ways to reduce the road cost. All initiatives, to be efficient, need a coherent national and regional transportation policy (for goods and persons) with a global view on a long run. But more than anything else, they need a mental revolution. Nurtured by advertisement, the dream of owning a car is based on a subconscious message: « I drive, therefore I am ». Change will only be possible if we can reconsider our own way of life…
Technologies for the future
The main challenge for transportation is probably to reduce gaseous pollution.
Cleaner technologies exitThis bus of the city of Grenoble, France, is using bio gas. It results in less air pollution, and less greenhouse gases emissions. |
Cleaner technologies already exist. For instance, less polluting fuel such as ethanol (stemming from beet, sugar or ether of colza) or high pressure direct injection systems should help reducing gasoline consumption. Moreover hybrid vehicles "electric-thermic" engines provide another alternative already development in Japan: built with two engines, (an internal combustion engine and an electric one), they are designed for both urban and road driving. But the real solution may come from the fuel cell, already used in space. With hydrogen as fuel, the only by-product is… steam. The advantage : zero pollution. The inconvenience : hydrogen and oxygen still poses storage and safety problems. Such technologies don't apply to cars only. Projects for the future are already emerging : the flying wing which should be geared up by 2020 will transport 1000 people by air and use 30% less fuel. On sea, the energy-efficient flying ship will « fly » on the water surface at 500km per hour… Enjoy your transportation !
