Further we travel the faster we go

<div>"Further we travel the faster we go"</div><div>data for figures 1-4.</div>Abstract:<div>The average travelling speed increases in a nontrivial manner with the travel distance. This effect leads to scaling relations valid on quite extended spatial scales, for all mobility modes taken together and also for a given mobility mode in part. We offer a wide range of experimental results, investigating and quantifying this universal effect and its measurable causes. The increasing travelling speed with the travel distance arises from the combined effect of: choosing the most appropriate travelling mode; the structure of the travel networks; the travel times lost in the main hubs, starting or target cities; and the speed limit of roads and vehicles.
