Thomas Delissen, Lukas Daniel Klausner, Maximilian Lackner, Torsten Priebe, Lőrinc Thurnay
TL;DR
Small towns and rural regions face limited data, budgets, and digital capacity, and metropolitan digital-twin approaches do not transfer directly. This study develops three stakeholder-selected prototypes for Lower Austria and finds that technical feasibility differs across data integration, simulation, and visualisation, with important constraints on traffic simulation.

Abstract
from arXiv · showhide
Smart city and digital twin concepts hold considerable potential for improving local governance and planning, yet practical implementations have almost exclusively focused on large metropolitan areas. Small towns and rural regions face a distinct set of challenges -- limited data availability, constrained budgets and lower digital capacity -- that make a direct transfer of urban approaches infeasible. This article presents results from the ongoing project "Smart Cities and Digital Twins in Lower Austria", which adapts digital twin concepts for small-town and rural contexts following a design science research approach. Based on stakeholder workshops with municipalities in Lower Austria, three use cases were identified and implemented as prototype digital twins: traffic flow planning (emphasising data integration), population growth (emphasising simulation) and shared spaces (emphasising visualisation). We describe the design and implementation of each prototype and report on a technical evaluation of their feasibility. Our findings highlight both the potential and the specific limitations of digital twins in resource-constrained settings and offer practical guidance for municipalities, policymakers and researchers working in non-urban contexts.
1 Introduction
Small towns and rural regions cannot simply inherit metropolitan digital-twin approaches because they face limited data, budgets, and digital capacity. The project adapts these approaches through three stakeholder-selected prototypes and identifies their feasibility and scaling barriers.
1 Introduction
- Rural and small-town contexts face limited data, constrained finances, and lower digital capacity, making direct transfer of metropolitan digital-twin solutions difficult.Their societal and demographic realities also differ from those of large cities.Source: §1 · pp. 1–2
- Workshops with Lower Austrian municipalities selected traffic flow planning, population growth, and shared spaces as locally relevant prototype use cases.Prototypes were built because abstract discussion can make digital twins’ functionality and benefits difficult for non-technical stakeholders to grasp.Source: §1 · p. 2
- The project demonstrates technical feasibility for small-town digital-twin MVPs focused on data integration, simulation, and visualisation.It also identifies barriers to scaling them into production-ready systems and offers guidance for resource-constrained settings.Source: §1 · p. 2
2 Background and Methodology
The study uses design science research to develop and evaluate three prototype digital twins as artefacts for small-town and rural use cases. Its evaluation is preliminary and technical; stakeholder evaluation and completion of the research cycle remain future work.
2 Background and Methodology
- The study treats three prototype digital twins as design-science artefacts, a form of instantiation described in the information-systems literature.The research follows the design science research methodology of Peffers et al..Source: §2 · p. 3
- The iterative research process moves from stakeholder-identified challenges through prototype design and development to feasibility and usefulness evaluation.Its cycle follows the five phases described by Vaishnavi and Kuechler, Jr., with adaptations informed by data, simulation, and visualisation constraints.Source: §2 · p. 3
- Three focused prototypes foreground data integration, simulation, and visualisation rather than pursuing one comprehensive digital twin.The implementations use state-of-practice technologies, prioritising feasible and usable artefacts over technical novelty.Source: §2 · p. 3
- The reported evaluation is preliminary and technical; detailed stakeholder evaluation is outside this article’s scope.The full design-science cycle is to be concluded after ongoing stakeholder evaluation in a follow-up publication.Source: §2 · pp. 3–4

4 Implementation of the Digital Twin Prototypes
The paper implements three minimum viable digital-twin prototypes, each foregrounding a different challenge: data integration, simulation, or visualisation. Feasibility varies by use case, while visualisation is generally the most feasible dimension.
4 Implementation of the Digital Twin Prototypes
- The fifteen-use-case analysis identified data integration, scenario simulation, and visualisation with interaction as recurring digital-twin needs.Each prototype emphasises one dimension: integration for traffic planning, simulation for population growth, and visualisation for shared spaces.Source: §4 · pp. 5–6
- Feasibility varied across the three use cases, and visualisation was generally most feasible because mature open-source 2D and 3D tools are available.The prototypes were selected from fifteen use cases and developed as minimum viable products.Source: §4 · p. 5
4.1 Traffic Flow Planning Use Case
- The traffic-planning MVP uses hourly traffic counts from Zwettl before and after the B38 bypass opened to show reduced traffic through town.Its map encodes hourly traffic volume through road width and traffic status through colour; category thresholds are illustrative and need domain calibration.Source: §4.1 · pp. 6–7, Figure 1 · p. 6
4.2 Population Growth Use Case
- The Baden bei Wien population-growth MVP simulates kindergarten service coverage as users adjust area populations and facility operations.Its Monte Carlo allocation distributes fixed kindergarten capacity among 22 areas by geographic proximity, with a configurable approximate 1.15-kilometre range.Source: §4.2 · p. 8
4.3 Shared Spaces Use Case
- The Traismauer shared-spaces MVP contrasts the existing street with a proposed redesign in an interactive 3D model.Users can move through the scene, change parking-car counts, and select times of day; the prototype prioritises visualisation over high realism or data integration.Source: §4.3 · pp. 9–10, Figure 3 · p. 9
5 Technical Evaluation
The technical evaluation found that small-town digital-twin prototypes were feasible in focused forms, but data gaps and context-specific simulation limit their scope. Web-map visualisation was comparatively easy to reuse, whereas detailed 3D modelling required substantial manual work.
Evaluation scope
- The evaluation is preliminary and technical: it assesses MVP integration, simulation, and visualisation needs, extrapolates effort for full twins, and leaves stakeholder evaluation ongoing.The article identifies technical challenges that would complicate implementing fully functional digital twins.Source: §5 · p. 10
Population growth
- Municipal open data cover current population broadly but not smaller-area breakdowns or service capacity, so assumptions constrain usefulness; configurable supply-demand inputs let experts model local conditions.The MVP calculates differences between service supply and demand based on population size, with relevant numbers entered by a domain expert.Source: §5 · p. 11
Shared spaces
- Shared-space twins can start from open street layouts, but textures require manual collection, mobility data are often unavailable openly, and impact simulation needs costly street-specific research.The required research is likely to be prohibitively expensive for most small towns.Source: §5 · pp. 11–12
Traffic flow planning
- Traffic planning used observed bypass changes, but future effects require town-specific estimates or simulation, and missing side-street counts require estimates; the twin would mainly visualise results.The available MVP data showed changes after the bypass was implemented, rather than estimating effects before construction.Source: §5 · p. 11
Visualisation
- Interactive web maps made traffic and population-growth visualisation relatively easy and reusable across Austrian regions where data exist; shared-space 3D modelling required substantial manual work.Building shapes could be generated from OpenStreetMap data, but realistic textures and street and pavement layouts were not readily automated or transferable.Source: §5 · p. 12
6 Conclusion and Future Work
The three prototypes show that digital twins are technically feasible for small-town use cases, but feasibility depends on the implementation challenge. Stakeholder evaluation is ongoing, alongside work on a tailored platform architecture and adoption roadmap.
6 Conclusion and Future Work
