Key messages

The volume of transportation of passengers is projected to increase at a rate of 1.4% per year, between 2005 and 2030. In comparison to past trends, the scenario shows a slowdown in the rate of increase of activity. Forecasts predict a gradual decoupling of transportation activity from GDP growth, a trend which is expected to be more accentuated in the long term.

Is there a trend of decoupling of passenger transport demand from economic growth?

The Baseline scenario of transportation activity, which includes details about flows of transportation between and within the EU Member-States, shows a gradual decoupling of transportation activity from GDP growth. This trend, which is more accentuated in the long term, is a combined result of productivity gains in transportation and certain saturation effects. The volume of  transportation of passengers is projected to increase at a rate of 1.4% per year, between 2005 and 2030 In comparison to past trends, the scenario includes a slowdown in the rate of increase of activity.
As regards passenger transport the slowdown is related to the stability of EU-27 population and to a longer-term trend which involves lowering the long-term income-elasticity of transportation reflecting saturation. More specifically, energy related transport activity per capita is projected to reach 17908 km per annum in 2030 up from 12769 km per annum in 2005.

This considerable increase of transportation of passengers (42% higher in 25 years) is accompanied by changes in transport modes towards using faster means, such as fast trains and aviation, a trend which keeps the average time spent by person on  transportation in this scenario within a realistic range.

The projections in the baseline scenario show domination of transportation by cars and motorcycles and also show a noticeable growth of air transport. Aviation for passenger transport has been the fastest growing mode of transport in the recent past, driven by rising real incomes, the increased willingness to pay for leisure, the globalisation process and the liberalisation of the air transport market. Aviation activity is projected to grow at a rate of 3.1% per year in 2005-2030. The need for more long distance travel facilitated by high speed of air travel is expected to drive this rapid growth, despite the increase in air transport prices due to high oil prices. By 2030 the market share of aviation in passenger transport activity is projected to reach 12.2% in 2030, up from 8.1% in 2005.

Rail transport activity, which exhibited a decline between 1990 and 2005, is projected to display acceleration of growth from 2015 onwards (+1.6% pa in 2005-2030) as a result of new and upgraded infrastructure projects facilitating networks of high train speeds. In 2030 passenger rail activity is projected to account for 7.5% of total activity (+0.4 percentage points up from its level in 2005, +0.6 percentage points up from 2015 level).

On the contrary the shares of the other modes, such as public road transport (+0.6% per year growth in 2005- 2030), private cars and motorcycles (+1.3% pa) and inland  navigation23 (+0.4% pa), are projected to slightly decline over the projection period. By 2030 road transport activity is projected to account for 79.7% of total activity down from 84.0% in 2005.

Indicator specification and metadata

Indicator definition

Definition:  Passenger transport demand is the total number of kilometres travelled by persons in a given year by all modes of transport (taxis, buses, trolleybuses, trams, underground, trains, inland water transport, maritime transport and airplanes) and by private transport. It can also be presented as a breakdown of total passenger transport demand by mode (modal split: the share of each mode in total transport demand).

Model used: PRIMES

Geographical coverage: EU25: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, United Kingdom, Cyprus, Czech republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia


The volume of the passenger transport is measured in the passenger-kilometre traveled (pkm), which represents one passenger traveling a distance of one kilometre.

Policy context and targets

Context description

Pan-European policy context

The large number of non binding policy instruments have been developed under fora such as Environment for Europe process, the European Council of Ministers of Transport (ECMT) and the UNECE/WTO Transport, Health and Environment Pan-European Programme (The PEP). The PEP was set up to address the key challenges to achieve more sustainable transport patterns and a closer integration of environmental and health concerns into transport policies.

EU policy context

The EU has set itself the objective to reduce the link between economic growth and passenger transport demand ('decoupling') in order to achieve more sustainable transport.

Reducing the link between transport growth and GDP is a central theme in EU transport policy for reducing the negative impacts from transport: 

  •  The objective of decoupling passenger transport demand from GDP was first mentioned in the Transport & Environment (T&E) integration strategy that was adopted by the Council of ministers in Helsinki. Here, the expected growth in transport demand was named as an area where urgent action was needed. In the sustainable development strategy that was adopted by the European Council in Gothenburg, the objective of decoupling is set in order to reduce congestion and other negative side-effects of transport.
  • In the review of the T&E integration strategy in 2001 and 2002, the Council reaffirmed the objective of reducing the link between the growth of transport and GDP.
  • In the Sixth Community Environmental Action Programme, decoupling of economic growth and transport demand is named as one of the key objectives in order to deal with climate change and to alleviate health impacts from transport in urban areas.

Shifting transport from road to rail is an important strategic element in the EU transport policy. The objective was first formulated in the Sustainable Development Strategy (SDS). In the review of the T&E integration strategy in 2001 and 2002, the Council states that the modal split should remain stable for at least the next ten years, even with further traffic growth.

In the White Paper on the Common Transport Policy (CTP) "European Transport Policy for 2010: Time to Decide", the modal shift is central and the Commission proposes measures aimed at the modal shift.

The White Paper on the Common Transport Policy also says that common transport policy alone will not provide all the answers. It must be part of an overall strategy integrating sustainable development, to include: a) economic policy and changes in the production process that influence demand for transport; b) land-use planning policy and in particular town planning; c) social and education policy;  d) urban transport policy; e) budgetary and fiscal policy to, to link the internalisation of external, and especial environmental, costs with competition of trans-European network; f) competition policy, to ensure, in line with the objectives of high-quality public services, and in particularly in rail sector, that the opening-up of market is not harmed by the dominant  companies already present on market; g) research policy for transport in Europe.

The European Neighbourhood Policy stressed that generating more trade and tourism between the Union and its neighbours, requires efficient, multimodal and sustainable transport systems. EU should develop an Actions plan for cooperation with its neighbors to improve the physical transport networks connecting the Union with neighboring countries, to step up aviation relations with partner countries with the aim to open up markets and to co-operate on safety and security issues.  The Action Plans will also contain specific provisions to address the vulnerability of transport networks and services vis-A-vis terrorist attacks. The highest attention will be paid to enhance the security of air and maritime transport.

EECCA policy context

EECCA Environmental Strategy recognizes the need to incorporate environmental concerns into transport policies and sets this action as one of the Strategy objectives.

One of the actions selected by THE PEP is 'demand side management and modal shift and with special attention to the needs of the countries of Eastern Europe, Caucasus and Central Asia (EECCA) and of South-Eastern Europe, as well as issues related to ecologically particularly sensitive areas'.

Methodology for indicator calculation

The indicator of the Passenger transport activity is produced using the transport module of PRIMES model. The model covers the horizon from 1990 to 2030 with 5 years periods.

Overview of the PRIMES Model

PRIMES is a partial equilibrium model for the European Union energy system developed by, and maintained at, The National Technical University of Athens, E3M-Laboratory. The most recent version of the model used in the calculations covers each of the EU Member States, EU candidate countries and Neighbouring countries, uses Eurostat as the main data source, and is updated with 2000 as the base year. The PRIMES model is the result of collaborative research under a series of projects supported by the Joule programme of the Directorate General for Research of the European Commission.

The transport module of PRIMES has been developed to study mainly the penetration of new transport technologies and their effects on emissions, besides the evaluation of the energy consumption and emissions in the transport sector. The emphasis is on the use of car technologies and on the long term (2030). The model structure is kept deliberately simple as it is made to interact as demand module with supply modules (refineries, new fuel production) of PRIMES.

The transport sector distinguishes passenger transport and goods transport as separate sectors. They are further subdivided in sub-sectors according to the transport mode (road, air, etc.). At the level of the sub-sectors, the model structure defines several technology types (car technology types, for example), which correspond to the level of energy use.

The overall demand for transport (passenger kilometres, ton kilometres) is determined by income/activity growth and by the overall price of transport. The overall price of transport is determined endogenously, as a function of the modal split and of the price per mode. The split of the overall transport activity over the different modes is driven by the price per mode and by behavioural and structural parameters. The price per mode depends on the choice of technology for new investment and on past investment for each transport mode. The technologies for new investment are chosen, based on the lowest expected usage costs.

The stock of vehicles inherited from the previous period is expanded in function of the transport needs per mode. The new stock composition determines the stock for the next period and influences the aggregate price per mode.

Rationale uncertainty

The relevance of the modal split policy for environmental impact of passenger transport arises from differences in environmental performance (resource consumption, greenhouse gas emissions, pollutant and noise emissions, land consumption, accidents etc.) of transport modes. These differences are becoming smaller on a passenger-km basis, which makes it increasingly difficult to determine the direct and future overall environmental effects of modal shifting. The total environmental effect of modal shifting can in fact only be determined on a case-by-case basis, where local circumstances and specific local environmental effects can be taken into account (e.g. transport in urban areas or over long distances).
