Including Accident Information in Automatic Bicycle Route Planning for Urban Areas

الملخص EN

Between 2005 and 2007 there were 9071 traffic accidents involving bicycles within London and this paper demonstrates the utility of Geographic Information Systems as a tool for analysing and visualising these occurrences.

Through linkage of these spatial locations to a street network dataset it was possible to create a variety of intelligence about the types of street infrastructure where accidents predominantly occur.

Additionally, a network routing algorithm was adapted to account for the frequency of accidents within a series of proposed journeys.

This pilot routing application compared the quickest route with an accident avoidance weighted route between a series of origins and destinations.

The results demonstrated that the routes avoiding areas of high accident volume did not increase journey length significantly; however they did provide a “safer” route based on empirical evidence over the volume of accident locations.
