Abstract: Abstract Current online route planning systems available do not provide options for using an ecological route search. In this project an attempt was made to create a route planning programme which optimizes nitrogen oxide (NOx) emissions through driving. For this purpose, published emission data for diesel vehicles with EURO 5 and EURO 6 emission standards (HBEFA 3.3) were used. It is expected that the emission factors for nitrogen oxide will influence the calculated routes compared to the fastest route. The program GraphHopper has been extended with weightings of nitrogen oxide emission factors for diesel vehicles in accordance to the EURO 5 and EURO 6 emission standards. OpenStreetMap data was used to provide map material. With the modified GraphHopper, three different routes were calculated. The fastest and the NOx-optimized routes were compared with each other. It could be shown that an ecological route guidance that takes the pollutant NOx into account is possible by modifying the GraphHopper. Roads with a maximum permitted speed of ≥ 100km/h such as motorways and country roads were predominantly avoided with a NOx-optimized route calculation. Low-speed roads such as roads in residential areas were also avoided. In all evaluated cases there was no NOx-optimized route found for which the estimated travel time is less than with a speed-optimized route calculation.
