PTV Vissim's pre-coronavirus simulation
Next, we need a pre-coronavirus base model in PTV Vissim to compare coronavirus simulations. PTV Vistro converts to PTV Vissim. This quickly exports our model geometry and signal controllers. The traffic signal offsets in PTV Vistro’s time-space diagrams are transferred. In Vissim, we can insert a 55-mph free-flow speed on our corridor. Even with congestion, Vissim shows that there are some pockets where motorists could exceed the speed limit, especially between intersections 1 and 3 shown below.
