A hybrid macro-meso solution was developed to enable a model-wide view while at the same time to drastically reduce modeling efforts. In the project study area, the simulation-based assignment (SBA) method is used, i.e., a dynamic method in which temporal changes of the supply as well as the waiting times resulting from junction control are considered. In the remaining part of model, vehicles are propagated through the network based on the macroscopically determined travel times, i.e. with static methods.
Analysis of the current situation is an essential part of the planning and improvement of Public Transport systems. This requires capturing and processing of data about passenger streams and their origins and destinations. Automatically collected data, e.g. from ticketing systems is increasingly used for that purpose in addition to classic passenger surveys. With PTV Visum 2023 we added the option “Access control at the vehicle and at the stop (location, time, trip information)” and “Access control at the stop”. By adding those options, it was possible to accelerate the plausibility check-in/check-out data considerably (by a factor of about 150). This is especially helpful regarding the high sample size (close to 100%) of such systems.
Cycling continues to receive more attention in transport planning. Since Visum 2022, there is a dedicated bicycle assignment. The biggest difficulty to date is the generation of a network that is suitable for modeling bicycle traffic. In Visum 2023, a new configuration ‘Detailed urban bicycle network’ has been added to the import of data from OpenStreetMap (OSM).
The new "Create Meso Network Nodes" function automatically creates the meso network nodes required for a mesoscopic simulation and therefore saves you time and gives a headstart for mesoscopic simulation. The prerequisite is that the network is suitable for a dynamic assignment and that the nodes for the dynamic assignments are of type "polygon".
With PTV Vissim 2023, car parks can be modelled even more realisticly - with vehicles parking forward or nose-out, or in any combination of both.
Vissim 2023 offers the possibility to compare networks and scenarios with each other and to display the differences in the form of an interactive tree and in the network editor.
The new function "Compare Current Network with Network File..." in the menu "File->Compare and Transfer Networks" allows you to compare the currently loaded network with another network.
Copy and paste of multiple selections within a network has been improved. This applies in particular to the behavior of selections of multiple objects that are not self-contained, i.e. if there are references to objects outside of the multi selection.
