Work on shared Visum models simultaneously through PTV Hub. When models are managed in PTV Hub, project members can edit the same model in parallel without relying on local files or manual synchronization. PTV Hub provides editing awareness, stores updated revisions and supports managed merging of changes from different users into the central model. Conflicting edits are flagged so teams can review and resolve them.

PTV Visum 2027 embeds model calibration directly into the modeling workflow. Users can define which parameters are adjusted, which measured targets must be met, and how the calibration process is structured. The framework then calibrates the whole model or selected parts using chosen optimization methods. Live and post-process convergence statistics support monitoring, reduce manual iterations, and make recalibration easier when targets or software versions change.

PTV Visum 2027 imports measured travel times from KPI corridors configured in PTV Flows. Historical travel times from real road segments are mapped to corresponding links in the Visum network, giving modelers direct access to observed network performance. This makes it faster to build and check realistic road models, validate modeled travel times, and use measured data in calibration workflows.

Access and egress to public transport can now be modelled without defining zone-to-stop connectors. Visum disaggregates zones to a virtual grid and allocates stops using catchment areas and time profiles, enabling high-resolution access and egress modelling with less effort in network building, checking and updating. The approach also makes stop-location scenarios easier to assess without increasing the licensed network size.

Assess public transport impedance and quality of service directly in PTV Visum using the Rooftop method from the UK Passenger Demand Forecasting Handbook. Rooftop skims are available within the model, reducing the need to export assignment results to external evaluation tools and reimport assessments. The method supports an established rail-planning standard and prevents quality-of-service results from being skewed by additional, less attractive connections.

Model ride pooling and on-demand services with greater control in Visum. Multiple, including overlapping, service areas can be considered while keeping each passenger within a single on-demand system. Requests can be filtered to avoid unrealistically short trips, and on-demand legs in public transport assignments can be limited to feeder or last-mile use.

Model restricted mixed use of public transport lanes in Assignment with ICA. Lanes reserved for buses can also be opened to selected vehicle groups, such as taxis, and assessed in the same assignment context. This lets planners evaluate effects on volumes and travel times, supporting decisions on where mixed-use lanes should be introduced and how access should be configured.

Estimate demand matrices using measured counts that correspond to groups of network objects rather than single elements. This is useful when count locations cannot be matched directly to individual links because of model granularity or the physical layout of the network. By aligning modelled volumes and observations at matching geographic levels, Visum reduces manual matching and aggregation work and speeds up calibration and model update workflows.

Generate more representative synthetic persons and households for activity-based demand models (ABM) in Visum. The improved population synthesizer accounts for aggregate statistics across different geographic levels and produces results comparable to outputs from PopSim. This supports fully integrated ABM workflows and scenario assessments without switching tools or transferring population data between applications.

Write custom Python scripts in Visum with less time spent consulting documentation. The script editor now provides code completion for both the built-in Python API introduced in Visum 2026 and the legacy COM API. This helps users enter supported commands and syntax more efficiently when extending procedure sequences with custom calculations or model-specific data processing.

Use updated COPERT data for environmental assessments in Visum. PTV Visum 2027 supports COPERT 5.9.2, helping planners apply the current emissions model when evaluating decarbonization and air-quality impacts. Visum continues to integrate COPERT alongside HBEFA, keeping emissions analysis available within established transport planning workflows.

Work on shared Vissim and Viswalk models through PTV Hub. When models are managed in PTV Hub, project members can edit in parallel instead of coordinating local files manually. PTV Hub provides editing awareness, stores updated revisions and supports managed merging and conflict handling. Teams can also attach cloud-based comments to network objects, helping modelers, reviewers and stakeholders communicate clearly in context.

Define complex lane layouts with less effort: A new editor for merging and diverging lanes gives direct access to lane geometries and connections. It helps users create and adjust lane configurations more precisely in complex intersections and merging areas, while supporting the improved simulation behavior introduced for these situations.

Model lane reductions with fewer workarounds: New merging connectors can start from multi-lane links and represent lane reductions directly. The added Arranging driving state lets vehicles on neighboring lanes deliberately create gaps before the merge, supporting fairer merging behavior and reducing the need for parameter tweaks.

Keep road information consistent across tools: Vissim now uses OpenDRIVE road markings to set lane change restrictions and improve visualization after import. New options for georeferenced models also preserve local Cartesian coordinates, helping AV testing workflows maintain consistent model information between different software environments.

Turn simulated dynamics into AV scenarios: The OpenSCENARIO export uses Vissim simulation results to provide replayable dynamic scenarios for third-party software and AV testing environments. Combined with incident detection, users can parameterize and filter simulations for interesting or challenging test situations.

Control pedestrian route splits deterministically: PTV Viswalk can now distribute pedestrians exactly between routes based on relative route flow values. This makes it possible to achieve precise route distributions within each decision interval and, when inputs are aligned, represent an exact OD matrix in the simulation.

Represent slower passenger flows at doors: A new Alighting Delay function lets users model delays when passengers leave a train, similar to the existing Boarding Delay function. This helps reflect situations where alighting flow is lower than cross-sectional door width alone would suggest.

Apply waiting behavior where it fits: Waiting behavior at a route waiting area and waiting behavior for a PT vehicle can now be used mutually in PTV Viswalk. This gives modelers more consistent options for representing how pedestrians wait along routes or for public transport vehicles.

Overlay project graphics without hiding the network: PTV Vissim 2027 supports transparent background images, so users can display only the relevant information while keeping links, connectors and network objects visible. It is useful for site plans, architectural drawings, schematic layouts, zoning overlays and other project-specific visuals.

Start projects with more ready-made references: The Vissim example library now includes added and updated models for roadworks with reversible lanes, cableways, rail crossings with barriers and a multi-storey car park. Users can import and learn from these examples to speed up project setup.

Coordinate cloud-based projects more clearly. Editing awareness shows who is present, who is working, synchronization activity and new committed revisions. Expanded PTV Hub Dashboard data, clearer intersection data sources and object-based comment titles support review. Multi-Change can activate AM, PM or event signal patterns across selected intersections in one operation.

Improve signal analysis precision with more consistent HCM timing calculations. Lost time is calculated from critical lane groups, while protected-permissive green-time analysis better represents the transition from protected to permissive movement. Minimum and maximum green times can use decimal values, helping users reflect field timing plans and imported Centracs Mobility or UTDF data more accurately.

Use initial stage-based signal control workflows for regions that use Vissig controllers. Users can work with signal groups, stages, interstages, intergreen matrices, sequences and signal programs, exchange controller data with PTV Visum and PTV Vissim, and export signal data to PTV Hub Dashboards. Global detector defaults and cleaner signal group handling support more consistent controller setup and data exchange.

Review unsignalized intersection operations more clearly. For two-way stop and two-way yield intersections, Rank 1 movements can now show delay in the Network Editor instead of a zero-value display. This gives traffic engineers a more meaningful graphical view of priority movement performance when checking intersection results.

Bring observed traffic data with less manual preparation. Centracs Mobility volumes can be imported directly and filtered by node, signal coordination group, full network, date range and weekdays. The Values import and export workflow also supports right-turn-on-red percentages, helping teams maintain consistent assumptions across scenarios and spreadsheet-based updates.

Prepare simulation outputs and share reports more efficiently. The PTV Vissim export now includes simulation start time, simulation period and warm-up duration, improving ANM exports for evaluation workflows. The PTV Vistro Web Report Viewer lets users compare up to 20 scenarios in a browser-based report and share the results as a self-contained ZIP file.

Get teams connected to PTV Hub faster with self-service diagnostics, clearer access roles and centralized release information. The diagnostics tool checks required domains, services, web maps, licensing connections, latency and throughput. A unified Reviewer and Author access model clarifies participation across desktop and cloud workflows, while release notes on the subscription homepage make recent improvements easier to follow.

Manage project access more consistently with reusable User Groups and Organizer-controlled visibility. Administrators can organize users by team, department, office or project, then apply groups to Workspaces instead of adding people individually. Organizer roles help control who can see organization-wide user information, supporting collaboration with internal teams and external partners while protecting broader user data.

Understand available desktop license capacity directly. The Licenses app now shows remaining and total seats, borrowed or occupied seats, and licensed modules or add-ons. This gives administrators and users a clearer view of the software capabilities available to the organization and reduces the need to check licensing information across separate systems.

Work on shared transportation models through PTV Hub with clearer coordination, revisioning and model management. Parallel and collaborative editing supports PTV Hub-managed workflows for PTV Visum, PTV Vissim and PTV Viswalk models, including editing awareness, managed merging and conflict handling. Teams can also duplicate models, track scenario component revisions, remove older base model revisions and run PTV Visum DRT calculations in cloud computing.

Communicate transportation results more clearly through more flexible PTV Hub Dashboards. Editors can create custom color classifications, preserve widget configurations when switching compatible data sources and provide free-text filters with operators such as contains, starts with and ends with. Larger sub-attribute combinations and backend performance improvements support more detailed PTV Vissim results and faster dashboard workflows.

Assess the operational cost of planned timetables with automated vehicle blocking. PTV Lines 2027 creates efficient vehicle schedules and shows fleet requirements, vehicle use and costs across service trips, deadhead trips, layovers and depot activities. Compare vehicle types, depot strategies, costs and layover rules to balance fleet efficiency with the required level of service.

Create presentation-ready public transport maps directly from the planned network. Highlight route diversions, extensions, shortenings and stop changes, then customize lines, stops, corridors, legends, text and icons. PTV Lines helps teams explain network proposals more clearly and prepare decision-ready materials without manually recreating maps in a separate design or mapping application.

Evaluate public transport accessibility with more representative departure assumptions. Instead of calculating results from one exact start time, PTV Lines 2027 lets planners define a time span and use the first available departure within that window. This reduces outlier results from missed connections and makes accessibility analysis easier to apply without repeatedly adjusting the start time manually.

Reflect operational layover requirements more accurately in vehicle calculations. Instead of relying on a fixed 16% assumption, PTV Lines 2027 lets planners define minimum layover times as a percentage of travel time, a fixed number of minutes, or both. The system applies the higher value automatically, supporting more realistic fleet, cost and schedule results.

Adjust timetable run times faster and more consistently across a line route. PTV Lines 2027 lets planners update run times for all stop points along a route at once, making it easier to apply travel time changes without editing each stop point individually. This supports more efficient timetable maintenance and reduces the risk of inconsistent manual adjustments.

Create clear visuals of a public transport plan directly from PTV Lines. Graphic Export lets planners use selected styles, annotations and visual elements to prepare presentation-ready outputs. Export settings are saved locally, so planners can return later with their previous setup restored automatically or reset to the default when needed.

Help operators focus on network conditions that need attention. Sentinel automatically detects unusually congested zones network-wide and notifies operators in near real time, reducing manual KPI monitoring. In PTV Flows 2027, critical zones are highlighted and ranked by “attention required,” so operators can triage events, inspect flagged zones, understand why they were detected and decide on action. Sentinel uses existing floating car data and requires no roadside installation for this capability.

Make better use of customer-owned traffic detection hardware in PTV Flows. The Detectors module connects data from loops, radars, cameras, parking occupancy systems and other detector sources directly into the software. Detector data can be ingested via API, then stored and analyzed historically in Historical Data Analysis (HDA). Users can replay detector history and review measured volumes in the HDA Replay map to support richer traffic information for operational analysis.

Evaluate the network over the relevant time horizon. Operational Planning KPIs in PTV Optima support a configurable forecast distance of up to 24 hours from the start of a simulation. This provides operators and planners with greater flexibility to evaluate network performance over longer planning horizons, supporting more informed decision-making across operational scenarios.

Bring external route and probe data onto the Optima network without building your own map matching system. The new Public Route Matcher service translates an ordered sequence of coordinates into the most plausible route on the Optima network. This service is available to developers and system integrators via a supported API. This means that integrations can be connected faster and interpret routes consistently, rather than each one having to maintain its own matching logic.
