Enriching OSM road networks with TMC LCL information

Increasing traffic, especially in urban areas, leads to more and more infrastructural bottlenecks and congestion inside transportation networks. The aim is therefore to use existing transport networks as efficiently as possible. Live traffic and incident reports from the Traffic Message Channel (TMC) are an important source of information to provide further services in the context of a dynamic routing. The state of North Rhine-Westphalia currently intends to organize the traffic information of the country in order to represent it to the road users in a new manner. The Road Construction Department of NRW has realized this development of an integrated transport information portal (Verkehr.NRW). In the portal address lookup table, a route planner and basic maps are provided. In order to furthermore integrate current traffic information in the portal, a road graph with TMC LCL information based on OpenStreetMap (OSM) is needed. To enable this service BASt (German Federal Highway Research Institute) agreed to implement the Location Code List (LCL) [1] for Germany into the OSM project. The part of the initialized MDM funded project "Enriching of an OSM road graph with TMC LCL information" was therefore now to develop a matching method to associate TMC/ LCL information automatically with crowdsourced OSM data.
