City-wide bottleneck and deficiency analysis on a road network generated from the Open Street Map road network using Floating Car Data (FCD)

Abstract

The German Highway Capacity Manual (HBS) and the German Guideline for Integrated Network Planning (RIN) rely on travel time distributions to assess the Level-of-Service (LOS) of roads and road networks. Usually, these values are generated by traffic measurements or with the help of traffic flow simulations. In recent years Floating Car Data (FCD) has become an essential data source for analyzing traffic quality because of its easy accessibility and growing coverage. This paper proposes a method to perform a city-wide analysis on the Open Street Map (OSM) road network using raw FCD. Therefore, OSM road segments of a city are aggregated to longer network sections on which travel times are estimated. Performance indicators can be calculated using these travel time distributions. Examples are shown for the cities of Karlsruhe and Hannover.
