  How can bicycles use contribute to an AQ improvement?

2. Introduction

   

Up to the middle of 1990s cycling and walking declined considerably and the policy makers tended to overlook these modalities. Especially in city centres, bicycle traffic is the ideal and most sustainable mode of transport. Going by bike for short distances (of 1 to 3 kilometres) is fast, flexible, healthy, requires a minimum of space for both parking and moving, and produces only little noise and no polluting emissions at all.


3. Discussion

   

A shift of transport towards bicycle traffic results always in an improvement of air quality. A research study conducted by the Umwelt- und Prognose-Instituts Heidelberg e. V. (Germany) showed that in a city counting 100,000 inhabitants, a 20 per cent shift of transport from motorised vehicles to bicycles results in a reduction of air pollution by 36%. Many European cities, notably those located in the Netherlands and in Denmark, have a large share of bicycle traffic in their modal split. German cities average is 11%, in some few middle size cities between 25 and 35% (some best performances in Germany: Münster, Dessau, Erlangen).

Further discussion points are:

  • Which methods can be recommended for public relation activities aiming to encourage bicycle usage (instead of individual motorised transport)?
  • How can cities ensure that an increase of bicycle usage does not go along with an increase of motorised vehicles to the disadvantage of public transport?

A real commitment to cycling is likely to involve reduction of road capacity for motorised vehicles: this may lead in short term towards congestion, though it is a strongly effective long term measure.

A relevant EC Project in the area of bicycle use is VELOINFO (see http://www.lutr.net/). The objective of VELOINFO is to enable local authorities and experts to attain sustainable urban planning by establishing a internet based expertise centre on bicycle planning policies and bicycle use. The usefulness and continuity of the expertise centre is ensured by the following project objectives: involve users and suppliers of cycling policy knowledge in the development of the system; make use of state-of-the-art technology for data storage, information disclosure and internet communication; create a critical mass of bicycle policy and user information in the expertise centre; establish a business model based on a co-operative network methodology; carry out an active marketing and dissemination from the start of the project and demonstrate and evaluate the usefulness of Veloinfo.


4. Recommendation / Conclusion

   

· Measures to give priority to cycles should be much more seriously considered in view of their clear benefits (mainly low capital costs and very limited impact on the environment) and the enormous potential of demand (around a quarter of urban trips are under 3 km in Germany and the United Kingdom) that can be shifted to cycling and walking.

· Public transport finds it difficult to take care of short distances, especially when these short trips are mainly located in suburban areas. The bicycle on the other hand has a high door-to-door capability and flexibility. The network of cycling and walking should be dense to allow direct access to any destination: connecting paths, shortcuts, passages through buildings and underpasses or bridges to overcome obstacles such as rivers, railway lines or motorways can reduce substantially the trip length.

· The waiting time at the traffic signals should be minimised with dedicated frequent short phases or free turning right. Measures such as wide pavements and separate cycle paths, levelled-off or continuing pavements and cycle paths at intersections, removal of obstacles such as kerbstones, smooth surface on cycle paths and speed humps not obstructing bicycle traffic are all contributes to the increasing of pleasure and convenience of cycling.

· The development of “greenways” based on footpaths, cycle-ways, and waterways is also a way of enhancing the environmental quality and the pleasure of cycling. Cycling can further be promoted by providing secure bicycle parking facilities near stations, shopping centres, schools, public buildings, etc.

· Advanced parking shelters (electronic card operated) for bicycles have been introduced on the market, electronic operated Public City Bike systems, and The Bicycle Lift are examples of the last years innovative technology which have been introduced to support cycling in urban areas.

· The significant use of bicycle as a transport mode can reduce virtually all the pollutants concentrations in urban areas, especially in environmental and central zones. In facts the use of the bicycle is alternative to the use of various polluting vehicles (motorcycles, diesel or benzene cars) which are responsible of the emissions of all the main urban air pollutants: CO, VOC, NOx, PM.

Best practices for a broad usage of bicycles can be found in most Dutch and some Danish and German cities. Yet, those cities benefit from their geographical situation (only small hills) which generally makes cycling more attractive. Other recommended practises include the city-bike concepts of Vienna and Copenhagen.

The City of Leipzig managed to increase bicycle traffic from 5,2% (1987; 1994: 5,8%) to 13,2% (1998) by taking or planning the measures and actions recommended above. Those actions will continue to play a major role in the cities policies in the years to come.

In Seville, the local Hispalense University initiated in 1996 a project to establish a cycling network for its 70,000 students who often have to change between different campuses. While Seville City Council will carry out the necessary construction efforts (new bicycle lanes), the university makes sure that all of its building can be accesses by bike and that secured bicycle parking facilities are established. The project responses the demands of students and contributes to a better circulation as well as to a healthier environment (for more information please consult: www.universidaddesevilla.com).

The Swedish City of Malmö is proud to call itself the “Cycling City” as the municipality provides approximately 370 km of cycling ways (2003; target to increase the length until 2013 to 520 km) compared to a street network for motorised vehicles of 900 km. Until 2013, the city aims to decrease car traffic by 2 – 3% and to increase bicycle usage by 10%. Estimations show that even the slight reduction of car traffic can reduce car emissions by 5% as short-distance car traffic (catalysts do not work at their optimum until the engine has reached its working temperature) is more pollutant. The chances to reach this goal are well as Malmö benefits from its topography and promotes safe bicycle lanes as well as secure parking facilities.

Other modal split data from selected European cities (share of bicycle traffic): Münster (D): 34%, Dessau (D): 27%, Basel (SUI): 23%, The Hague (NL): 24%, Freiburg (D) / Amsterdam (NL): 20%, Parma (I): 19%, Potsdam (D): 17%, Cologne (D) / Bern (SUI): 15%, Strasbourg (F): 12%, Dresden (D): 10% (see http://www.dresden.de/index.html?node=6725), Frankfort am Main (D): 6%, Dublin (IRL) / Chemnitz (D): 5%.

Copenaghen (Denmark). Within its integrated traffic plan a stong emphasis was put on the further development of cycling, which already accounts for 30% of home to work trips in the summer compared with 37% of public transport and 30% of the private cars.

Erlangen (Germany) has been promoting a cycling policy for over 20 years by developing a dense network of cycleways accompanied by detailed signalling and parking facilities and priority is given to cyclists on certain routes. As a result cycling has more than doubled its share of city traffic since 1974 (from 14% to 29%). In the same period the car traffic remained stable at around 40% but the share of pedestrians has fallen.

Groningen (The Netherlands) implemented a programme to favour the use of bycicle and public transport based on the idea to implement restrictive parking policies near facilities, shopping centres, and other attractive locations. The city also improved its bus service through the integration of different networks with separate bus lanes and priority at the traffic signals. Groningen is today the world third ranking city for the bicycle use.

Trondheim (Norway) City centers surrounded by hills commonly have heavy air pollution with a negative effect on cycling. Steep hills foster steep inclines in the suburb–center linkages, which are also serious barriers to cycling. Hilly cities may therefore have a bigger unrevealed potential of cycling, than flat cities and clever located Bicycle Lifts may reveal this interesting potential. The lift will reduce the strain and unwanted sweat of people who want to use bicycle as their daily form of transport. Normally the bicycle lift carry the cyclists up onto topographically higher levels, where you have less pollution, less noise and less conflicts with the car traffic. Since the installation of the Bicycle Lift, cycling in this particular area of Trondheim has increased by 150 %. More personal trips are now being made by bike than by public transport and Trondheim has a general increase in cycling which rates the highest in Norway.

This positive effect is not due to the lift alone (the prototype is not more than 130 m long) but there is no doubt that the lift has raised the general image, attention and motivation of cycling in Trondheim. The normal lack of consistent proof of its effects on peoples biking habits is a major deterrent to a faster market penetration.
