Route Analysis and Planning for Urban Transportation on Basis of Floating Car Data and Emission Estimates

Transport carriers and forwarding agents have to cope with time-dependent traffic volumes and densities, high fuel prices and hard competition. Roadside cargo transportation is characterized by the interaction of public interests like security of supplies, climate goals and sustainability. A methodology for the provision of dynamic routings in urban road networks for delivery is proposed. Opposite to static approaches, Floating Car Data (FCD) and enriched emission estimates based on the new version of the Handbook of Emission Factors (HBEFA 3.1) are used to obtain more realistic estimations. Route indicators like shortest time (ST), shortest distance (SD), a hybrid time-distance criterion (Cost) and lowest carbon footprint are compared using data from the urban area of Vienna. Test trips from probe car data with high temporal resolution are compared to predicted results generated with the proposed approach. Deviations are up to 20% in travel time (TT), 9.5% in CO2 and 16% in costs. An individual planning case shows differences between a static and hourly dynamic routing of up to 90% in TT and up to 50% in carbon dioxide (CO2) emission. Depending on indicator and time domain, average deviations for a large set of simulated routes are up to 15% in route length, 17% in (TT, 11% in costs and 13% in CO2 emissions. Transport companies can benefit from comparisons of own routes with predicted ones, showing potentials for monetary savings. Another use-case is found in advanced planning of delivery routes in urban areas.
