AMS Unravelling Urban Pedestrian & Cycle flows

Two-day conference unveiling key societal and scientific questions and collaborative thinking about solution directions.  

In recent years, we have seen that cities are becoming increasingly busy, yet the space available has not increased to any significant extent. Besides this, in cities such as Amsterdam, the proportion of ‘slow traffic’ is steadily growing. Although there are many reasons to welcome this trend, the increase in pedestrian and cyclist flows is also causing problems.

AMS Institute and TU Delft recently started a new scientific program to unravel pedestrian and cyclist flows in cities. The kick off of this new program is a two day conference, geared towards establishing the key societal and scientific challenges on this subject. Additionally, our purpose is to jointly think about approaches to increase this so called ‘slow mode mobility’, while at the same time ensuring that the negative side effects are kept within acceptable bounds. Please be welcome and share your professional ideas at this conference. 

Day 1 (16th of July) deals with the bicycle, while day 2 (17th of July) deals with pedestrian flows and the management thereof in cities. Topics include accessibility, safety, flow operations, wayfinding, management and control, use of ICT, data collection, design, and general trends and developments (e.g. re-urbanisation, lifestyle changes and the role of the car, impacts of changing demography, impact of the e-bike). The different topics will be introduced by a selection of top national and international speakers.

Day 1: trends in cycle use and their impact (10:00 – 17:00)
The first day of the conference is dedicated to the bicycle.

In the morning, we will focus on the changing role of the bicycle as a means of transport. We will look at different trends that influence this change, such as demographic changes, changing role of the car, the e-bike, re-urbanisation, etc.), the impact of these trends and the opportunities they result in, as well as means to further increase the attractiveness of the bicycle as a (multi-modal) transport means. An important aspect here is also the prediction of bike share for future transportation scenarios, and requirements with respect to models that would allow for accurate forecasting.

In the afternoon, we will focus on the potential bottlenecks that may results from the increasing role of the bicycle, in particular focusing on the urban context. Examples are safety issues, parking and orphan bike pollution, bike queuing, etc. Also here, data collection, and modelling will be issues that will be discussed.

For both the morning session and the afternoon session, the key topics will be introduced by a selection of key players in the field. After these introductions, break-out session are held to further discuss the issues, formulate solution directions, and key knowledge questions.

Day 2: Impacts of growing pedestrian flows and solution directions (10:00 – 17:00)
On the second day of the conference, we focus on pedestrian mobility and the many aspects that relate to it.

In the morning, we will cover the different issues that become relevant when pedestrian flows grow in different types of facilities and conditions (events vs regular situations, urban areas vs transport facilities, indoor vs outdoor). Although each environment is characterized by its specific issues, common issues are likely to come forward as subject for further research, forming the basis for key knowledge questions.

In the afternoon, we discuss the different opportunities that technology will bring, both to better ‘sense the crowd’, but also to optimize the utilization of the available infrastructure and get a better understanding of pedestrian behavior in urban areas on all levels: operational, tactical and strategic. These approaches might form a starting point to alleviate the problems identified in the morning session.

During the breakout sessions we discuss the issues introduced by key players in the field. Moreover, we will try to find the common knowledge gaps (in the morning) and identify potential solution directions (in the afternoon).
