Land use and urban planning have a key and long lasting influence on the mobility need. This is especially true in areas with economic growth and on transportation of people and goods. There is also on influence on the environment and a strong economic impact.

Essential changes in the settlement structure of European countries
Pre industrial era:Natural settlement structureAll the activities in the proximityNo need to travelLow or (even none) mobility
general theory of modern urban development (for example Berg, Drewett, Klaassen, Rosi, Vijveberg, 1982, Tosics 1988 or Cheshire and Hay, 1989).

Essential changes in the settlement structure of European countries
Industrial era - Phase 1: urbanisation:development of technology is a key factor influencing the development large industrial complexes are established in settlements and grow rather quickly mass production, distribution as well as consumption of goods Technological changes in one area are always accompanied by changes in a social and urban structure structure

Essential changes in the settlement structure of European countries
Industrial era - Phase 1: urbanisation:residential development took place in the proximity of factories and centres usual form was that of a radial-concentric city - a star-shaped urban conglomeration the arms of which extend in the shape of roads
Further up growth was experienced as a result of developing transport Industrial urban development culminated by establishing coherent urbanized areas

Essential changes in the settlement structure of European countries
Industrial era - Phase 1: urbanisation:
In Central Europe and in Eastern Europe special features different from the general model:
changes are often delayed by several decades
transformation of the settlement structure is not so aggressive “socialist urban development” after the World War 2nd (commuting, undeveloped infrastructure, limit of urban growth)
Transport Research Centre Brno 8
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:
new phase of the socio-economic evolution economic activities are shifted from the industrial production to services
knowledge, skills and supply of information “economy of services”, (theories of Daniel Bell, John Kenneth Galbraith, Zbygniew
Brzezinsky, Kenneth Boulding and Amitai Etzioni)
Transport Research Centre Brno 9
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:changes in the settlement structure
attenuation of heavy industry and departure of workers to the tertiary area
light industries producing on assembly lines requiring single-floor industrial halls with large areas
high-tech operations are built in suburban areas where their construction does not cost so much
Administrative and research parks thereby follow industrial parks
Transport Research Centre Brno 10
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:
advantage of new, fast roads, cheaper construction plots and ample parking space
Administrative parks represent cheap locations for companies that are not established yet and need cheap start-up conditions
Shopping centres have grown almost spontaneously along outward-bound roads and motorways
Cities are thereby chaotically extended at the expense of agriculturally utilized countryside
Transport Research Centre Brno 11
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:increasing numbers of population are leaving large cities (characteristic of richer population)
living environment and infrastructure in the suburbs are improving (shops
and facilities have followed people) People who have an opportunity to get means of individual transport change their places of living An increased use of cars enables greater groups of population to move quickly between their homes and workplaces these processes are usually not coordinated and occur independent of the existing transport system, distances are ever increasing, put pressure on the use of cars and disadvantage public transport (De Boer, 1976).
Transport Research Centre Brno 12
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:unhealthy social trends “social exclusiveness” of new locations increased concentration of socially similar groups uncontrolled growth of cities polluting the environment with exhalations collapsing transport system cities suffer from the fact that in many places cars have pushed out life represented by pedestrians
Transport Research Centre Brno 13
Essential changes in the settlement structure of European countries
Phase 2: Suburban development:gradual process in which public transport looses its meaning and subsequently ceases As a result, numerous categories of population, senior citizens in particular, have an aggravated access to transport and their spatial mobility is decreasing
living in the fresh country air near the nature but with a necessity to commute to the city is much less healthy than living in city centres

Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :changing production technology Export articles are increasingly de-materialized; they consist of information, services or innovations Companies providing services also migrate to places with cheaper land and labor cooperating network of smaller operations, active in great distances from city centres This trend has instigated an immense development of distant transmission of information (faxes, mobile telephones, computers connected in networks, the Internet, telecommunication satellites, etc.). companies and financial operations can be controlled from more distant locations
Transport Research Centre Brno 15
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :
not appropriate urban planning policy Due to traffic congestions inner parts of cities are becoming less accessible for their inhabitants
non-regulated growth of cities,
crises of transport systems and
increased individual use of cars due to the construction of commercial shopping centres and residential zones,
and sometimes due to non-coordinated residential building
Shopping and cultural centres are also built outside the city in the proximity of motorways
Transport Research Centre Brno 16
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :Conditions for enabling the transport to become more intense are also established
costly transport and parking facilities are built
consequence - a massive mobility of people and devastation of the environment (even beyond the borders of the affected regions)
“urban sprawl”
Transport Research Centre Brno 17
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :Historical centers
problem has been created by ill-considered and non-regulated growth of administrative buildings in European city centres Adjacent historical squares then automatically became parking places damaged environment deteriorates construction of speedways connecting suburban developing locations with the central part of the city
destruction of the central parts of the city by enhancing the dispersion of functions crucial for the centre (concentration of retail, light production, recreational, cultural and educational functions, vital for this part of the city)
Transport Research Centre Brno 18
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :negative attitude towards pedestrians
increased use of cars dramatically damages the environment no space left for pavements – restrictions for seniors and handicaped
great distances do not enable access other than by cars drawbacks of the city, such as bad quality of environment, crime, growing poverty in central areas and other negative phenomena
tendency of inhabitants to leave cities is increasing as the cities become uninhabitable

Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :
discrepancy between the layout of the urban structure and the present-day requirements made by the volume of traffic
Transport Research Centre Brno 21
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :
Historical centres image of city centres is aggravating
“crisis of cities”, “decline”, “pathology”, “alienation” and
decreasing investments in these areas
Changed accessibility and deteriorated quality of the environment (noise, air pollution, vibrations, etc.) may induce migration
People of higher status move out of these locations because they feel that they are becoming less inhabitable
Transport Research Centre Brno 22
Essential changes in the settlement structure of European countries
Phase 3: Urban de-development :
population is quickly declining; the same applies to the number of job opportunities
transformation
Some parts of the city lose their function or become inhabited by groups of lower status
consequently, social problems start to occur, social polarization in urban residential areas: they are considerably socially fragmented and segregated
Need to rehabilitate the living areas that are becoming redundant
Transport Research Centre Brno 23
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentideal would be to have a compact city with the mobility protecting the living environment
adopting legislative measures slowing down the suburban de-development,cooperation among managers, new approaches, cooperation and mediation
Transport Research Centre Brno 24
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentprevention and restriction of social exclusiveness
restoring central parts
and evener distribution of job opportunities in the city structure
decreasing volume of transport (micro-electrotechnics)
Transport Research Centre Brno 25
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentUrban development - a tool for making the cities more attractive for business, investments and tourism
restoring street systems, urban avenues, embankments and squares
building new and restoring old parks, or building shopping streets and parking areas
Transport Research Centre Brno 26
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentrevitalization, gentrification, renewal - when the transformation of the negative, “dead”, “poor” and “non-productive” environment
into something positive, “live”,
is emphasized; the quality of the environment
Transport Research Centre Brno 27
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentThe renewed cities
Impact on urban ecology
given preference to humans over cars
supported and developed public transport,
restricted individual transport, effective public transport
which can decrease the volume of private transport by up to 20-30%
Transport Research Centre Brno 28
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentThe renewed cities
building intra-city optimised transport routes,
good quality city public transport
constructing cycling routes and
pedestrian zones
Transport Research Centre Brno 29
Essential changes in the settlement structure of European countries
Phase 4: Urban re-developmentCompact urban structure
mobility protecting the environment
higher economic effectiveness
city centres more attractive;
costs of infrastructure, such as transport routes, will also decrease
Transport Research Centre Brno 30
Essential changes in the settlement structure of European countries
Phase 4: Urban re-development
Compact urban structure
the denser the population within the city,
the lower the requirements for transport and the greater space for free countryside and wild nature
Transport Research Centre Brno 31
Essential changes in the settlement structure of European countries
Phase 4: Urban re-development
Compact urban structure principal recommendations for urban and regional planning by European Transport and Environment Federation
Various surveys of power consumption in transport have shown an unambiguous link between the population densities, distances between places of activities, individual cities and power consumed in transport
Transport Research Centre Brno 32
Essential changes in the settlement structure of European countries
Phase 4: Urban re-development
Compact urban structure “... the need for travelling sharply declines if the population density of a given place increases to 50 persons per hectare. If the population density is lower than 30 persons per hectare, the dependence on cars seems to be inevitable... (Greening Urban Transport, 1999).
Transport Research Centre Brno 33
Essential changes in the settlement structure of European countries
Phase 4: Urban re-development
Compact urban structure The cities with the population density of 17 persons per hectare and with the most decentralized residential structure use 70% more power than cities with 33 persons per hectare and with high concentration of flats” (Greening Urban Transport, 1999).

Interactions between land use, traffic and public transport networks
Concepts for a sustainable land use in different European regions and
cities. increase the share of public transport, walking and cycling, decrease the use of cars, and reduction of traffic volume, saving green spaces for … This should also include transport demand and its interactions with land use and public transport networks.
Transport Research Centre Brno 36
Land use and traffic in cities and regions – integrated planning
there is a need for: An analysis of the cost of urban sprawl and of external framework (traffic priority, city centre parking, road pricing…) in relation with the public transport An analysis of the relationships between land use planning, urban development and development of traffic. Understanding mechanism influencing people and firms preferences for places Impact of commercial activities inside public transport networks: how to improve economic balance and attractiveness of public transport? Public transport planning and settlements choices: how to take one another into account
Travel modes and space consumption
Transport Research Centre Brno 37
Impact of public transport on social equity
Public transport is generally considered as brining a social service to people that needs it. Does public transport really play this role? It is to be checked. Fare systems are often in favour of people living in inner cities - meaning financially able to live there.Compared to revenues, transport cost is often very high for those living in far suburbs. The social impact of urban sprawl and the way to bring more social equity through the organization of the network and its fare system should therefore be much more studied.

Why people like to use cars?
Psychological aspects of car dependency
Transport Research Centre Brno 39
Why people like to use cars?
Study of Stradling et al. (1999) – investigation of motives for car use2 main emotional benefits: feeling of independence and personal identityLinda Steg et al. (2000): car can increase subjectively perceived quality of life (ASI project), senior citizens – when give up driving?
Transport Research Centre Brno 40
Symbolic value of a car
Connection to social and personal identity of an individualRepresents driver´s status, lifestyle, values
Transport Research Centre Brno 41
Symbolic value of a car
3 basic functions: instrumental, symbolic and emotionalRole of needs, values, motives, preferences and attitudes (internal factors)But also infrastructure conditions, sociodemographical factors (external factors)
Transport Research Centre Brno 42
Symbolic value of a car
Steg (2003): correlation between car usage and feelings of control and powerdesire to be able to reach any point by car, which often relates to the feeling of freedom Influence of social motives –
1. social comparison, 2. self-prezentation, 3. privacy in the car (compared with the public transport)
Focus on comfort and mobility
Transport Research Centre Brno 43
Theory of self-concept
Reed (2002) – based on a concept of material-self: people have strong emotional feelings to different material object and these feelings are tightly connected to their self-concept
Transport Research Centre Brno 44
Campaigns on using public transport
Campaigns should be based on what people think is normal (Harland et al., 1999)
Focus on personal norms – altruistic behaviour, environmental friendly
Accent on traffic safety
Racional arguments
