Quick start guide Calculating emissions based on emission classes

The Quick start guide shows you the main steps for using emission class distributions for vehicle types, how to enable emission calculation, optional deactivation of peripheral links and connectors, and the selection of possible evaluations.

Note: For the Bosch emission calculation you need the add-on modules Emissions and Bosch. You must have a license for an add-on module.

Tips:

First read the description of the emission calculation (Calculate accurate emissions with Bosch Cloud Service)
A Vissim network with predefined emission class distributions for typical fleet compositions based on HBEFA can be found by default in the installed example data directory of your Vissim installation. From this network you can additionally read the emission class distributions into your Vissim network (Reading a network additionally).
You can additionally read the emission class distributions from the example network into your Vissim network (Reading a network additionally). Check whether predefined emission class distributions in the example network meet your requirements. Import only necessary distributions. This reduces the time required for the import.

1. If the emission class distributions from the example network do not meet your requirements, you can define new emission class distributions and specify the desired proportion of emission classes in each of them (Defining emission class distributions).

2. Assign the appropriate emission class distribution to each vehicle type for which emissions are to be calculated (Configuring emission calculation for a vehicle type).

3. If your vehicles are to enter the area of the Vissim network where you want to have emissions calculated for these vehicles with the exhaust tract already warm, extend the link on which the vehicle will be inserted upstream and position the vehicle input accordingly. This applies in the dynamic assignment accordingly for the origin parking lot.

4. From the Evaluation menu, choose > Configuration.

The Evaluation Configuration window opens.

5. Click the Emissions tab.

6. Activate the Bosch emission calculation active option.

7. If you want to switch off emission calculation for individual links or connectors, deactivate the attribute Emission calculation of link or connecting link (Attributes of links), (Attributes of connectors).

When starting a trajectory, Bosch uses emission calculation data based on the operating temperature of the exhaust tract. This way, emission calculation results are not influenced by different operating temperatures of the exhaust tract when a vehicle travels through several Vissim network sections containing activated and deactivated links or connectors.

8. If you want to collect the calculated emissions aggregated per link segment, select the Links evaluation and the option Collect link results > per link segment (Showing data from links in lists).

9. If you want to collect the calculated emissions aggregated for the entire network, select the Vehicle network performance evaluation (Vehicle network performance : Displaying network performance results (vehicles) in result lists).

10. If you want to visualize results as a color scheme on links in the network editor, select the classification for segments in the graphic parameters of links in the Color scheme configuration, the attribute of the emission calculation and the desired color scheme (Assigning a color to links based on aggregated parameters).

11. You can also visualize results as link bars (Graphic parameters for display of link bars and lanes),

12. You can also display results in charts (Creating charts).

13. Make sure you have an Internet connection.

14. Start the simulation (Selecting the number of simulation runs and starting simulation).

15. Wait until the Bosch Cloud Service has transferred the calculation results to Vissim.

16. If you have configured evaluations, select the desired result list in the Lists > Results menu:
