SUMMARY:NERDS Seminar: Tom Brughmans
DESCRIPTION:Tom Brughmans\, Aarhus University: Archaeological Network Research\, illustrated through a study on visual signalling networks of Medieval strongholds in Garhwal Himalaya\, India.  \nThis presentation provides a brief overview of network research in archaeology. What are the past phenomena typically studied using network methods in archaeology\, and what empirical datasets tend to be represented as network data? When were these approaches adopted and how did the popularity in their application change over time? \nIt will illustrate some aspects if this field through a recent study of network Medieval strongholds in the Himalayas (co-authored with Nagendra Singh Rawat and Vinod Nautiyal; Rawat et al. 2021). Hundreds of strongholds are dotted throughout Garhwal Himalaya\, Uttarakhand\, India\, occupying elevated positions on ridges and mountain tops in the Central Himalayan region. We show that new survey data allows for more complex theories about the fortification phenomenon in Garhwal Himalaya to be addressed for the first time\, and we focus in particular on theories concerning visual signalling: the use of fire\, smoke or light for communicating between Medieval strongholds in this Himalayan region. Do sets of strongholds form communities of small local-scale communication networks and can these be identified as small administrative units or independent chiefdoms? Can an integrated visual signalling network have existed to allow for efficient communication throughout the entirety of Garhwal Himalaya? \n\nRelevant references \nRawat\, N.

His research interests include the study of Roman economic and urban phenomena\, past social networks\, and visual signalling systems. He performs much of his work by applying computational methods such as network science\, agent-based simulation and geographical information systems. His research projects MERCURY and SIMREC developed educational resources and case studies to make simulation studies of the Roman economy more common (Leverhulme Early Career Fellowship and Marie-Curie Individual Fellowship). His ongoing project MINERVA aims to develop a highly detailed network model of the Roman road system\, and perform simulation experiments to explore the centuries-long distribution patterns revealed by Roman tableware and amphora data. Tom’s research blog houses resources for archaeological network research.

SUMMARY:Invited Talk Michael Szell at PhyMo22
DESCRIPTION:Towards a human-centric urban data science\nMaking our cities better and sustainable is key to solving the climate and urban transport crises. To this end\, urban data science offers new tools to quantify societal problems in cities and to propose human-centric solutions to policy makers. In this talk I outline our recent and ongoing efforts towards that end\, focusing on urban transport and vulnerable road users. I discuss inequalities between transport modes through mobility space and collision threat distributions\, and automated methods based on network science to generate and merge bicycle networks and to identify their gaps\, for different urban development stages. All research comes with concrete policy recommendations that significantly increase urban livability\, public health\, and decarbonization.

SUMMARY:NERDS Seminar: Giulia Reggiani
DESCRIPTION:Understanding bikeability of urban networks\nGiulia Reggiani\, Delft University of Technology\n\n\nAbout the author:\nGiulia Reggiani is ending her PhD in the department of Transport and Planning\, Delft University of Technology. Her research in the last 4 years focused on structural properties of bicycle networks worldwide and on data driven methods for assessing bikeability. Her current interests lie in the broad domains of smart mobility\, data analysis\, and sustainability. \nAbout the presentation:\nHaving a bicycle network that is fully separated from vehicular traffic is not realistic even for top-performing cities. Thus\, cycling in most countries entails switching between streets with different length\, safety\, and comfort levels. As a consequence\, the quality of bicycle networks should not be evaluated based on one but multiple factors and by considering the different preferences of the users between the factors.In this presentation I will define and analyse different types of bicycle networks and present findings on bicycle infrastructure development across 47 cities. Then\, I present a multi-objective methodology to assess bikeability per origin-destination (OD) pair and for the entire network\, useful for evaluation and planning of bicycle networks. I do so by introducing the concept of “bikeability curves” which allows to assess how bikeable a network is for for its heterogeneity of users. This methodology is showcased on two cities with different bike cultures: Amsterdam and Melbourne. \n\n
