Other Models

The following models are derivatives of the core models and are sole responsibility of the developers (are not peer reviewed nor scrutinized by the ERMES Group).

NEMO (Network Emission Model) is a tool for the simulation of traffic related emissions in road networks. Typical applications reach from emission inventories for cities, regions and countries to complex measures like environmental zones or promotion of alternative propulsion systems.
NEMO combines both detailed calculation of the vehicle fleet composition and simulation of emission factors on a vehicle level. The simulation of the emissions of the different vehicle layers is based on the correlation of the specific engine emission behaviour (emissions in grams per kilowatt-hour engine work) with the cycle average engine power in a normalised format. The parameterisation of NEMO is based on data from European in-use measurements which are also used for the Handbook Emission Factors of Road Transport.

SIBYL is a tool for estimating emissions, internal energy consumption and costs given stock projections. It allows the formation and execution of scenarios, policy assessment and target setting. A detailed EU-wide vehicle stock baseline database has been hardcoded in the application so that the user can evaluate custom scenarios on real life data.

TREFIC (TRaffic Emission Factor Improved Calculator) is a tool to estimate atmospheric pollutant emissions from road traffic. The calculation is currently based on COPERT 4 methodology, but a flexible mechanism enables the user to implement its own emission factors.
Input data include vehicle fleets, traffic volumes and speeds with the related time modulations. The I/O is GIS-based, allowing to describe vehicle fleets, traffic volumes and speeds, with their related time modulations, on arbitrary sets of line and area objects. TREFIC is especially oriented to feed atmospheric dispersion models and its output is compatible with all the main model types: Gaussian, puff, Lagrangian particle and Eulerian photochemical ones, including speciation and lumping.
TREFIC has been used on several applications of different complexity, from single roads to urban and national networks with more than 50000 links, for off-line inventories and in real-time modeling applications.

TREMOD (Transport Emission Model) was designed in the late 90s on behalf of the German Federal Environmental Agency to build up a suitable tool that covers the state of knowledge for emission calculation in Germany. It is constantly updated and used for Germany’s national annual emission inventory reports, the projection of past trends and future scenarios for all transport modes.
For each year between 1960 and now and in scenarios until 2050, TREMOD analyses all means of passenger transportation (cars, two-wheelers, busses, trains, aircraft) and all means of freight transportation (lorries, light-duty commercial vehicles and articulated trucks, trains, inland navigation vessels, aircraft). The transport performance of all these vehicles and for road transport also the vehicle mileage is estimated. This mileage of road vehicles is further differentiated by federal motorways, all extra-urban roads as well as urban roads; additionally the annual mean mix of traffic situations on the different road types is estimated. Energy use and emissions of nitrogen oxides, sulphur dioxide, hydrocarbons (NMHC, CH4, benzene), carbon monoxide, carbon dioxide, particulate matter and soot can thus be calculated in the respective differentiation. Emissions are presented as direct emissions, i.e. emissions directly emitted by the vehicle, as well as indirect emissions, i.e. emissions from the upstream energy generation and supply chain.
In the road transport sector TREMOD has a close cooperation with the HBEFA: TREMOD uses the methodology and database of the HBEFA for the emission factors of road transport. Vice versa the HBEFA uses traffic activity data for Germany of TREMOD. The emission inventory, therefore, covers the same layers as the HBEFA with a high resolute calculation procedure.

COPERT Australia is the first dedicated non-EU application of a European software, resulting from a joint effort of EMISIA and the Queensland Department of Science, Information Technology, Innovation and the Arts (DSITIA). It comprises a MS Windows application for calculating greenhouse gas and air pollutant emissions from road transport, covering all important vehicle classes and driving conditions in Australia.
The COPERT Australia software includes algorithms that are developed from data collected in Australian test programs designed to reflect the Australian fleet and activity data. COPERT Australia is designed to be used for road transport emission inventories across Australia and potentially become a harmonized national prediction tool.
