PRELIMINARY PROGRAMME

Online format puts its limitations on what the audience can cope with. Therefore, we spread the conference events between three half-days. To accomodate for different time zones, two of them are taken in the European afternoon (=morning in Americas) and one in the European morning (=tolerable evening hours in Australia and Asia).

Note also that the parallel session presentations will be pre-recorded, meaning that you will have a possibility to see them even if you miss a session (Q&As will go live without recording).

Special session I

During the COVID-19 pandemic many cities have temporarily implemented measures to increasing cycling (and make cycling safer). Pop-up bicycle lanes, decreased speed limits and cycling streets have been known as effective measures for ages, yet the pandemic created the right momentum that helped to shift focus away from motorised transport towards cycling needs.

This session presents a collection of cases from around the globe, discusses what the cities have done and how the implementation process worked out. Furthermore, it will discuss how the temporarily measures can be developed into permanent ones and how the pandemic crisis can be a starting point for a real transition towards a safe and sustainable transport system, where cycling is no longer marginalised.

Invited speakers

Title (Oliver Maier, Bosch / Germany)

COVID-19 Impacts on Cycling, 2019–2020 (Ralph Buehler, Virginia Tech & John Pucher, Ruttgers University / USA)

Pop-up bike lanes and temporary shared space in Vienna during COVID-19 pandemic (Harald Frey, Barbara Laa & Ulrich Leth, Technical University Vienna / Austria)

Bicycle-friendly transport policies and resident’s quality of life: evaluating the impact of new bike lanes on a major road in Frankfurt am Main, Germany (Martin Lanzendorf, Clara Scheffler, Laura Trost & Simon Werschmöller, Goethe University Frankfurt / Germany)

Chairman

The session is chaired by Till Koglin, Senior Lecturer at Transport & Roads, Lund University (Sweden). His research mainly deals with mobility, transport and urban planning with a strong focus on the marginalisation of cycling in urban space. Within this domin, Till combines critical theory with transport and mobility in order to shed light on injustice issues within transport transport systems.

Keynote speech I

Marco te Brömmelstroet
University of Amsterdam
Netherlands

Marco te Brömmelstroet holds the chair of UrbanMobility Futures at the University of Amsterdam. He studies the role of narratives and world views in our thinking and doing in the mobility domain. In his article ‘Framing Systemic Traffic Violence’, he critically examines the ways in which society talks about the decade-long and ongoing carnage in our public space. In his talk he will address how we implictly take this violence—and its systemic nature—for granted when we focus on individual behaviour in many traffic safety campaigns. Why haven’t we been succesfull in truly eradicating systemic violence from our doorsteps? And why do we try to teach people to cope with the machines rather than redesigning the machines to cope with human behavior?

Special session II

The session will focus on essential issues related to a safe system for cycling by presenting some major components of such a system. A starting point is the analysis of predicted injury development based on increased cycling in Sweden from a comparative perspective in relation to the sustainability goal for active mobility. Further, the session presents examples and ideas of how various traffic safety factors like infrastructure design, speed management and protective devices can mitigate and prevent accidents and severe injuries for cyclists.

The session is organised in close co-operation with the Swedish Transport Administration (Trafikverket).

Torkel Bjørnskau
Institute of Transport Economics
Norway

Torkel Bjørnskau has more than 30 years of experience in traffic and transport safety research and has been involved in numerous national and international research projects. His doctoral dissertation from 1994 was on the application of game theoretical models to study road user interaction, which he also has used to study cyclists interactions with other road users. Since 2007, Torkel has been the chief research officer responsible for the programs ‘Risk research across modes’, ‘Transport Safety’ and recently ‘Behaviour and transport’—in all of them having cycling behaviour and safety as the key elements.
