The significance of real driving fuel consumption and emissions compared to laboratory tests has grown both because of emissions testing faults publicity and inclusion of real world emissions measurements in the new worldwide harmo-nised light-duty vehicles test procedures (WLTP). Urban driving represents approximately one third of distance in the WLTP real driving test. City driving conditions differ essentially by city environments, weather and traffic conditions. To analyse the urban driving variations a 25 km route was selected in Riga city comprising major city transport arteries in both directions. The route contains 15 km of road sections with coordinated traffic lights control. The city street configuration allows formation of green wave just in one direction so the other direction formats an organized traffic restraint. Street sections with three different traffic control conditions have been compared. The sections with coordinated traffic lights control in the green wave direction show the biggest around the clock variations which may be essential to note when real driving emissions are measured. The sections in the controlled traffic restraint direction may be useful for real driving tests where repetitive driving conditions are preferred. Up to five times higher fuel consumption has been measured in peak traffic hours compared to night driving. The paper analyses suitability of the route for urban driving tests by analysing average speeds and fuel consumption during 24 hours of urban traffic changes. The paper blends in a more extensive research on energy consumption in urban driving. © Transport Means - Proceedings of the International Conference. All rights reserved.
