Data driven simulation of bicycle traffic at intersections

Bicycling offers an inexpensive, environmentally friendly and compact option for urban mobility. However, issues with bicyclist safety persist in most countries. Driver assistance systems that warn drivers of the presence and potential actions of bicyclists are one possibility for mitigating these issues. In order to develop and evaluate such systems, microscopic traffic simulation software that is capable of realistically simulating bicycle traffic is necessary. However, the flexible behaviour of bicyclists makes it difficult to realistically simulate bicycle traffic using currently available simulation software. Here, a method for extracting behaviour patterns of bicyclists at intersections from video data is presented. These observed patterns are integrated with a microscopic traffic simulation, increasing the realism of simulated bicyclist behaviour and enabling the development and evaluation of driver assistance systems.
