      <title>Uppdatering EVA-kalkylen: nya emissionsfaktorer beräknade med PHEM</title>
      <link>https://trid.trb.org/View/1492583</link>
      <description><![CDATA[The current European emission model, HBEFA, specifies emission factors for different driving patterns and vehicle types. This model does not study the example of individual intersections. This study utilizes the same microscopic model, PHEM (www.tugraz.at), as HBEFA to calculate also intersection emissions and emissions of links without intersections. With PHEM the release of four vehicle types (cars fueled by diesel or petrol and trucks with and without trailers) calculated for several different road classes according to the division still used in the models EVA and CAPCAL. To illustrate the emissions of intersections calculations for emissions for a quick stop to rest and then the withdrawal of the original speed is also presented. In addition to a description of the method of how the new emissions have been calculated in the new tables also include suggestions of future updating of the model. In addition, reported the conclusion of tests and comparisons to facilitate the transition from the current basic model VETO to PHEM. The calculations show that previous assumptions about the significantly lower emissions of vehicles have not been met, and that the vehicle speed impact on emissions has changed., We suggest that more vehicle types will be included in the model at the next update. The model simulates the CO2, SO2, fuel consumption, HC / VOC, CO, NOx, NO2 and exhaust particles, but the report only presents fuel consumption. However, all other parameters can be obtained directly from the authors. The report first provides a brief description of the different emission models, how the calculations are done up to now and then how adaptations and updates led to the resulting emission factors.]]></description>

      <title>EMISSION FACTORS FOR COMMERCIAL AND ALTERNATIVE FUELS. MAIN REPORT</title>
      <link>https://trid.trb.org/View/541330</link>
      <description><![CDATA[The aim of the project was to develop emission factors for commercial and alternative fuels such as alcohols and methane. The background to the decision to carry out the project was that there was a need for emission factors for some other KFB project organized within the "system study" carried out by KFB. The method used for the project was to use the today's emission levels and the knowledge about the emission control technology as a base for the estimation of future emissions levels and the coming development of vehicles and the emission control technology. The results of the analysis and the estimations show that there exists a positive development concerning emission control technology and emission levels. However, the future positive development for alternative fuels strongly depends on the possibility of these fuels to capture a market which will have certain impact on the willingness and the economic possibilities for the car manufacturers to also invest in the development of alternative fuels. (A) All data which this report is based on are found in KFB-Meddelande 1997:23, see IRRD 9805VT028E.]]></description>
