Modern navigation systems calculate, e.g., shortest, fastest and dynamical routes based on their different routing algorithms. Collective traffic management strategies from cities advise specific routes due to specific traffic situations. In addition, car industry produces more and various electrified vehicles from light/mild hybrid up to fully electric vehicles. In an urban region with many stop-and-go situations the electric vehicle has its advantages. The paper illustrates how precise traffic information might influence engine dependent routes of the vehicles. A method to estimate such vehicle specific resource consumption will be introduced. First results of microscopic traffic simulation in an urban environment reveal information for the individual routing of vehicles. The concept will be presented for the given conditions in the city of Düsseldorf. The conclusions are: (1) The electrification of engines gives new opportunities for routing criteria of navigation systems in vehicles: due to the different engines, in urban traffic congestions different routes might be vary regarding to efficiency and resource consumption. (2) The public funded German project URBAN brings together relevant players in the this field: the infrastructure partner Düsseldorf with its strategic collective route guidance plus its software partner GEVAS, the service provider TomTom with its precise dynamic traffic information, the University Duisburg-Essen with competence in traffic simulation and the car manufacturer Daimler with onboard navigation systems and different engines. (3) The described concept will firstly reveal empirical data and calculation algorithms for the influence of traffic congestion on the resource consumption in vehicles in urban areas. (4) First empirical results give the impression, that for simulated data (similarly to measured TomTom data) in congestion on a short urban route of 600 m with traffic lights and waiting queues can give an average relative additional fuel consumption of 72% compared to undersaturated traffic. (5) The further project will implement the chosen approach and come up with more detailed scientific results.
