Optimal bikeability of urban street networks — •Christoph Steinacker, David Storch, Marc Timme, and Malte Schröder — Chair for Network Dynamics, Institute for Theoretical Physics and Center for Advancing Electronics Dresden (cfaed), TU Dresden

Individual transport in cities is most commonly enabled by private cars, an unsustainable status quo both ecologically and socially. In particular on intra-city length scales, cycling constitutes a broadly accessible and more sustainable alternative. However, insufficient and poorly designed bike lanes often hinder more prevalent bike use.

Here, we aim at identifying bike lane networks that enable fast and safe bicycle travel in cities. Evaluating bike-sharing data on millions of city trips, we estimate bike travel demand and find optimally bike-friendly network topologies. In a reverse percolation process starting from ideal conditions of a complete bike lane network, we successively neglect the least used bicycle paths. Intriguingly, even just a few bike paths, if chosen wisely, may already result in a strongly bike-friendly network. Our results may support the planning of street networks towards more sustainable individual transport.
