Motorisation development and motorisation saturation – The case of Karlsruhe COST 355 Madrid Bastian Chlond Tobias Kuhnimhof Institute for Transport Studies University of Karlsruhe
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 1 Agenda Motivation Karlsruhe and its transport system The motorisation and its development in the quarters of Karlsruhe influencing factors measures to influence behaviour Conclusions
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 2 Motivation COST Changing behaviour towards a more sustainable transport system Examples of changed behaviours Heterogeneous development of car ownership rates in Germany Investments in Germany both in Public Transport and Road Infrastructure Wrong investments against the background of increasing car ownership and cohort effects ? Do we have measurable effects of parallel investments ? Do the investments and planning measures / restrictions affect the level of motorisaton?
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 3 Why Karlsruhe? Perhaps a typical European town inhabitants (still slowly growing) Mixture of industry, administration, research, education Wealthy region, rated amongst the Top Ten in Germany Karlsruhe is a car town: Carl Benz lived and studied here Rastatt and Wörth are neighboured with car manufacturing plants Other automotive industry Comparably low housing density
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 4 Driving in Karlsruhe - Usability of a car Car driving is all too easy! Spare capacities available! Fair supply in infrastructure Reasonable achievable speeds Parking lots available (Nearly) no congestion Bypassing easily possible
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 5 Why Karlsruhe? Karlsruhe is known as a city for environmentally friendly modes! Cycling A city – mainly – in in the plains Drais – the inventor of the bicycle invented it in Karlsruhe Cycling routes and paths available nearly city-wide Cycling as a real alternative! Public Transport In the 70ies Karlsruhe did not abandon tramway operation Extension of the tramway network both inside the city and more of outside into the region mainly in the 90ies The Karlsruhe-model as the combination of railway and tramway operation

Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 9 Results – Before and after comparison of the demand on new Stadtbahn corridors About 40% of the passengers changed from the car to the Stadtbahn. Does this affect the level of car-ownership in Karlsruhe ?
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 10 Some Figures 365 public transport trips per year and resident 30% of Karlsruhe senior citizens own a season ticket
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 11 Effects of the Public Transport system: Real estate prices Good accessibility of every place in the city and in the region by Public Transport In spite of the economic power moderate price levels for housing and real estate Relatively small range in prices compared with other cities and regions Large suburban region with a lot of commuting commuting into KA commuting out The ubiqituos availability of Public Transport of high quality smoothens the real estate price differences not only within the city but also within the region!

Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 20 Possible explanations: parking restrictions and charging New planning concepts introduced after 1993 Traffic calming in all housing areas (30 km/h) except the main roads Number of short term parking-lots was massively reduced, the fees were increased by 300%. Parking spaces are always available No car traffic searching for free lots Steady enlargement of the areas where parking is with costs Parking fees in public spaces : 2 / hour in the inner city 1 / hour around the city suburban centers first hour 1,50 any further hour 0,50
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 21 Possible explanations: continous success of carsharing
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 22 Typical Suburbs: the Black Forest Villages Wealthy villages with low unemployment rate Low quality public transport, no car sharing Parking available Few shops
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite : Opening of new tramway Demographic effect: suburb with sufficient parking and low quality public transport - Aging and shrinking population Typical Suburbs: the Black Forest Villages
Institut für Verkehrswesen, Universität Karlsruhe COST 355 -Saturation Seite 24 Conclusions In spite of a growing wealth and a reasonable usability of a car a saturation in car-ownership observable Saturation depending from specific situation Successful policies as a combination between parking restrictions enhancement and improvements of Public Transport Investments into the Public Transport system rises the wealth and social balance High level of car ownership does not mean heavy car use A change of trends and in behaviour towards more sustainability is feasible!
