11 to 14 June. Building on established Velo-city discourse topics such as mobility, ecology and climate, health, the economy, resources, time and space, and social policy, the motto of the Velo-city 2013 conference, which took place in the Rathaus, was framed as “The Sound of Cycling – Urban Cycling Cultures“ with three main themes: cycling cultures, cycling cities, and cycling benefits. Aims Vienna is a growing cycling city that aims to raise the bicycle's modal share from the current 6% (2011) to 10% by 2015. Hosting the premier international cycling planning conference, Velo-city was therefore considered to be of great importance to reach this goal. In addition, the City Government of Vienna has declared 2013 the Year of Cycling in order to improve public opinion on cycling, to make urban cycling more attractive, and to convince more people in Vienna of the advantages of cycling as everyday mode of transport. Moreover, the Vienna Cycling Week took place in the week of the conference, offering various side events not only for Velo-city participants but also for the wider public. Program Amongst the subsessions such as lectures, podium discussions, round tables, lightning talks, and workshops participants were offered several inspiring plenary sessions and panel discussion as well as the so-called Speed Dating – Dating Cycle. Monika Jones, international journalist and presenter at Germany's global TV broadcaster ‘Deutsche Welle’ was not only the Master of Ceremony but also chaired numerous sessions during the conference. Plenary and panel discussion speakers included: Maria Vassilakou, Michael Häupl, Amanda Ngabirano, Stephen Yarwood, Dave Horton, Alain Flausch, Lenore Skenazy, Mikael Colville-Andersen, Shipra Narang Suri, Ulrich Syberg, Manfred Neun, Georg Hauger, Milan Ftacnik, Morten Kabell, Jacques Garreau, Randy Neufeld, Alec Hager, Michael Cramer, Hep Monatzeder, Sabine Kubesch, Per Ankersjö, Bernhard Ensink, Niki Berlakovich, Mathieu Grosch, Siim Kallas, Marijke van Haaren, Philippe Crist, Ursula Zechner, Roman Bartha, Doris Bures.
