The 3rd International BinN Research Seminar “Network configuration and multi-scale behavior analysis” will be held on March 4th 2015. The keynote speaker will be Dr. Richard Connors from the Institute for Transport Studies (University of Leeds). Dr. Connors is currently doing research on network equilibrium and topological configuration of transportation networks. His lecture will focus on understanding how network configuration impacts performance. In addition, two researchers will discuss their research regarding travel behavior and the recognition of behavioral space.

Summary:
The optimal spatial scale of analysis of travel behavior differs given the target behavior of interest. As a result, modelling travel behavior in micro, meso and macro scale is necessary to adequately analyze and evaluate transportation networks. In addition, scale aggregation is sometimes necessary not only to match the scale at which spatial recognition is conducted by individuals, but also to reduce calculation costs. This seminar aims at deepen the discussion regarding the relationship between spatial configuration and travel behavior in a multi-scale framework.

Title & Abstract
”Ensemble Analysis of Transport Networks”
How does the topological configuration of a transport network impact upon its performance? Answering this question is difficult because the space of all possible transport networks is large (of high dimension). Moreover, each network in this space could have flows arising from a high dimensional space of all possible demand matrices. Nevertheless, we seek to answer this question by bringing together characterisations of the topology, structural properties and spatial embedding of transport networks. We adopt an approach from Network Science and generate ensembles of synthetic road-like networks in order to systematically test performance as a function of topology. Here I set out a methodology and highlight the research questions that need to be considered within this process of generating synthetics networks, grouping them into ensembles and analysing their performance.

Brief Bio:
Dr Richard Connors is a senior research fellow at ITS-Leeds, UK. He has published research on a range of transport problems, including models for network equilibrium, bi-level network design, quasi-dynamic traffic assignment, network reliability and predictive accident models. Richard’ s current research considers characteristics of urban systems that arise from the spatial configuration of transportation infrastructure. The aim, in the context of transport systems, is to understand how network configuration impacts upon network performance, to what extent universal features emerge and can be identified in such systems, and hence how to establish methods to model urban evolution on the aggregate scale that consistently represent the underlying networked infrastructures. This research framework comprises work on: the analytic aggregation of network equilibrium models; network evolution algorithms; empirical ensemble analysis of synthetic planar networks; multi-objective optimisation of urban spatial evolution.
