Step 3: Generate demand outputs
To generate the demand outputs, we will use the macro network loading part of the hybrid macro-meso model. For the hybrid model, the macroscopic area is modelled using individual vehicles which are generated dynamically with the travel time calculated using delay functions without capacity restraint, flow metering or blocking back. This means that we can see how the demand at a particular junction changes over time, given the assumption that all vehicles can complete their journey.
It is possible to run a hybrid macro-meso without specifying a meso area. In doing this, if the travel time computation doesn’t introduce any delay (instantaneous or free flow travel time), the output flow represents a demand, as there is no capacity restraint anywhere in the network.
Start off by creating a new dynamic scenario with the same demand, control plan and public transport plan as the Throughput Scenario. In addition to this, add the path assignment plan that we created in step 2.
