VWI Verkehrswissenschaftliches Institut Stuttgart GmbH

What VWI Verkehrswissenschaftliches Institut Stuttgart GmbH does

VWI Verkehrswissenschaftliches Institut Stuttgart GmbH is a privately held German consulting firm specializing in planning, economic evaluation, and applied research for public rail-bound and road transport systems. The firm traces its origin to a 1929 institute founded by Prof. Pirath at the Technical University of Stuttgart and was restructured in 2002 into a non-profit association (VWI e.V.) and the operating GmbH. Its portfolio combines fee-for-service consulting (feasibility studies, Standardisierte Bewertung cost-benefit analyses, capacity investigations, operational planning, traffic forecasting) with a suite of proprietary software tools — PULEIV (railway infrastructure performance), PULZUFA (train dynamics), RUBIK (real-time passenger information for regional buses), Sinn² (accessibility app), RUDY/GeoRBL (route-flexible disruption management), and the Verkehrsmodell (four-step traffic demand model on PTV VISUM).

The firm operates an enterprise field-sales model targeting public transport operators, railway infrastructure companies (notably DB Netz AG), municipalities, regional authorities, and federal/state transport ministries. Projects are commissioned directly through formal bidding and long-standing client relationships, primarily in Baden-Württemberg and across Germany, with selective international work in Norway, China, and France. Revenue is generated through commissioned professional services; there are no disclosed pricing models and no product-led SaaS revenue at scale.

VWI holds a quasi-standard-setter position in Germany's federal Standardisierte Bewertung methodology — the cost-benefit framework used to justify federal funding for public rail investments — having been commissioned by the Bundesministerium für Digitales und Verkehr to update the methodology itself. The firm maintains close cooperation with the Institute for Railway and Transport Systems at the University of Stuttgart, publishes the Neues Verkehrswissenschaftliches Journal, and has won the Deutscher Mobilitätspreis (2019) and the VDV ITCS Award (2005). With 8-11 staff, VWI is a micro-cap, niche-dominant consultancy whose strategic significance substantially exceeds its headcount and revenue scale.

Core offering

VWI provides commissioned consulting and planning studies for public rail-bound transport — feasibility studies, standardized economic evaluations, capacity and infrastructure investigations, traffic demand modeling, and operational planning — for public transport operators, railway infrastructure companies, municipalities, regional authorities, and federal/state ministries. These services are delivered alongside a portfolio of proprietary analysis software (PULEIV, PULZUFA, RUBIK, Sinn², RUDY/GeoRBL, Verkehrsmodell) developed over decades and used across the German rail network.

Product overview

VWI Stuttgart GmbH is a specialized planning and consulting firm and research institute for public rail-bound transport. It operates as a unified portfolio combining proprietary analysis software tools with expert consulting services. The core software suite includes PULEIV (railway infrastructure performance analysis), PULZUFA (driving dynamics calculations), the Verkehrsmodell (traffic demand modeling using PTV VISUM), RUBIK (real-time passenger information and connection assurance for regional buses), Sinn² (barrier-free smartphone app for passenger information), and RUDY/GeoRBL (route-flexible disruption management). These software tools are complemented by expert consulting services for transport planning, feasibility studies, economic evaluations, capacity studies, and operational planning. The company also publishes the 'Neues Verkehrswissenschaftliches Journal' with over 30 issues. The organization traces its roots to 1929 and maintains close ties with the University of Stuttgart.

Brands

• Neues Verkehrswissenschaftliches Journal: Scientific journal published by VWI since 2004, covering transportation research topics

Products and services

• PULEIV railway infrastructure performance simulation Simulation software that automatically generates compressed timetables, calculates throughput-based capacity and waiting time functions, determines the optimal performance range, and localizes infrastructure bottlenecks on railway networks. Used by VWI on planning projects for rail infrastructure managers such as DB Netz AG.
• PULZUFA rail vehicle driving dynamics Tool that calculates minimum running times, electric energy requirements from the catenary, free lateral accelerations, and timetable running times for EBO and BOStrab rail vehicles (diesel and electric traction), using axle data from planning tools.
• RUBIK connection assurance and passenger information Lightweight, vehicle-based real-time passenger information and connection-assurance system for regional bus operators that replaces a central control room with a communication server, uses standard mobile industrial PCs in vehicles, and enables bus-to-bus direct communication for passenger connections. Integrates with the ZDD BW data hub and EFA-BW timetable information.
• Sinn² barrier-free passenger information app iOS smartphone app providing real-time passenger information for visually and hearing-impaired public transport users via the two-sense principle (at least two of hearing, sight, touch), leveraging standard iOS text-to-speech. Winner of the Deutscher Mobilitätspreis 2019 in the 'Best Practice' category.
• RUDY / GeoRBL route-flexible disruption management Route-flexible disruption management system that integrates geodata into computer-controlled operations control systems (RBL), enabling ad-hoc defined detours to be tracked and offering learning-based disruption management with a driver display via navigation interface. Many techniques from RUDY/GeoRBL have since been incorporated into commercial RBL/ITCS products.
• Verkehrsmodell und verkehrliche Rechnung traffic demand model Traffic demand modeling tool implementing a four-step algorithm (trip generation, trip distribution, modal split, traffic assignment) using behavior-like group concepts, currently running on PTV VISUM. The model is calibrated against count data and used for infrastructure and service evaluations.
• Public transport and rail planning & consulting services Comprehensive planning and consulting services for public and rail-bound transport, including conceptual and preliminary route/station planning, operational planning and timetable design, traffic impact modeling, standardized cost-benefit analyses (Standardisierte Bewertung), business-economics analyses for infrastructure and operations, vehicle and depot design, and capacity/infrastructure performance studies for roads, rail, and airports. Client base spans transport operators, municipalities, regional authorities, and federal ministries.
