Promoting Walking in Paris: A Multiple Criteria Decision Approach

This study explores how Multiple Criteria Decision Aiding (MCDA) can enhance pedestrian mobility in Paris. Despite historical prioritization of pedestrians in European cities, car dominance has created environmental and safety issues. The paper discusses the benefits of walking, pedestrian needs, and effective measures to promote walking, such as traffic calming and legislation. It presents a case study of Paris's vehicle-free areas in the Marais and how MCDA can facilitate decision-making processes by evaluating multiple objectives and fostering collaboration among stakeholders.

  1. Multiple Criteria Decision Aiding to Promote Walking in Paris Maria Lucia Galves University of Campinas - UNICAMP Campinas, São Paulo, Brazil LAMSADE - December 2008

  2. Campinas is located about 100 km North of the state capital São Paulo • Its population amounts to 1 million inhabitants LAMSADE - December 2008

  3. Outline • Introduction • Characteristics of Walking • Pedestrians’ Needs • Some Measures to Promote Walking • Contribution of MCDA to Pedestrian Mobility • Concluding Remarks LAMSADE - December 2008

  4. European cities have historically been devoted to pedestrians However, car driving has been given more and more priority in investment programs Consequences  safety and environmental problems Introduction LAMSADE - December 2008

  5. Introduction • It is necessary to bring back pedestrians as citizens of greatest importance (COST Action C6, 2001). • Benefits of walking: • Excellent way to meet people and enjoy city life • Healthy • Environment-friendly (no fuel, no emissions) • Money-saving (only clothes and shoes) • Free (no taxes) LAMSADE - December 2008

  6. Characteristics of Walking • Many trips are on foot. • The average length of walking is about 1 km. • Pedestrians are not a homogeneous group: LAMSADE - December 2008

  7. Pedestrians’ Needs • Accessibility • Adequate walkways to reach public transport, workplaces, schools, etc. • Safety • Protection against collisions with vehicles • Security • Protection against threats and assaults • Comfort • Absence of obstacles and barriers, slopes, trash, etc. • Attractiveness • Pedestrians are sensible to beauty! LAMSADE - December 2008

  8. Some Measures to Promote Walking • Design and management of the mobility space • Organisation: Free foot space (vehicle free areas), Traffic integrated space (20 miles areas), Motor transport space (major strees, busways) • Traffic calming (humps, chicanes) • Wide and direct walkways • Pavement • Street furniture: seating, signing, lighting • Vegetation LAMSADE - December 2008

  9. Some Measures to Promote Walking • Legislation • Traffic restrictions and control • Pricing • Taxes and tolls • Information and education • Walking as a healthy and pleasant means of transport LAMSADE - December 2008

  10. Phases of the decision-making process (Simon, 1960) Stages in problem solving (Dewey, 1910) Structuring What is the problem ? Intelligence Design Inventing, Developing, and Analysing possible courses of action What are the alternatives ? Evaluation Which alternative is best ? Recommendation Choice Multiple Criteria Decision Aiding Multiple criteria decision aiding LAMSADE - December 2008

  11. Activities in Structuring LAMSADE - December 2008

  12. Contribution of Multiple Criteria Decision Aiding to Pedestrian Mobility • Example • The City of Paris decided to create a vehicle-free area in the Marais • Some streets are closed to motor vehicles on Sundays from • 10 am to 6 pm in winter • 10 am to 7:30 pm in summer LAMSADE - December 2008

  13. Contribution of Multiple Criteria Decision Aiding to Pedestrian Mobility LAMSADE - December 2008

  14. Contribution of Multiple Criteria Decision Aiding to Pedestrian Mobility • Some questions: • Who participated in this decision? How? • Which objectives were taken into account? • How was this area defined? • Why creating a vehicle-free area only on Sundays? • Were other alternatives considered (a vehicle-free area the whole week or a 20 miles area)? • Was there any type of evaluation? LAMSADE - December 2008

  15. Concluding Remarks • MCDA could contribute to answer these questions by: • Providing a methodological support to coordinate the different phases of the decision-making process • Promoting communication between the actors • Creating meaningful alternatives • Evaluating the alternatives on the basis of an agreed set of objectives LAMSADE - December 2008
