Fink, Lechner and Wolff – CONCENTRIC METRO MAPS 2014

Description

This concise two-page academic paper, authored by researchers Martin Fink, Magnus Lechner, and Alexander Wolff from Universität Würzburg, introduces a novel method for automatically generating ‘concentric metro maps.’ Likely published in the early 2010s, it departs from traditional octilinear styles by utilizing mixed-integer linear programming (MIP) to construct maps using only circular arcs and radial segments around a designated center. The document details the mathematical framework, optimization criteria, and practical implementation, aiming for both feasibility and aesthetic quality. It features two clear figures illustrating concentric maps for Vienna and Montréal, showcasing the proposed design style compared to conventional inputs. This work offers a significant contribution to graph drawing and cartography, providing a robust computational approach for creating visually distinctive and structurally emphasized transit network visualizations, inspired by manual designs like those of Maxwell Roberts.
