Accurate, Scalable Data at the Core
CRS4 — the Center for Advanced Studies, Research and Development — is a leading Italian research institute dedicated to applying computational technologies to scientific and industrial innovation.
Based in Pula and Cagliari, CRS4 plays a pivotal role in projects that combine data science, AI, and quantum computing to solve real-world challenges.
Within the CTE Cagliari Digital Lab project, an initiative focused on digital transformation and smart-city innovation, CRS4 is exploring how advanced computation can optimise mobility systems for cities of the future.
“At CRS4 we are performing R&D on fleet optimisation via quantum computing and hybrid solvers. The insights gained from algorithm evaluation on accurate data at scale. from TravelTime, deliver significant value to our work.”

For CRS4, accurate, multi-modal journey time calculations, delivered at vast scales, are hugely important. To make their research truly reflect the dynamics of real-world mobility, CRS4 has partnered with TravelTime, the leading travel time API.
Senior Researcher, Giuliana Siddi Moreau, says: “We are happy to partner with TravelTime, their APIs are perfect for the smart-city scale in the CTE Cagliari Digital Lab project framework.”
Together, CRS4 and TravelTime are merging accurate travel time data with quantum optimisation models, creating a powerful testbed for fleet optimisation and city-scale mobility solutions.
Real-World Routing Challenges
Modern cities are living systems. They are constantly changing as people, vehicles, and infrastructure interact in real time.
For researchers, this poses a significant challenge: how to develop optimisation algorithms that can perform reliably across such diverse conditions.
CRS4’s team set out to test quantum and hybrid solvers for fleet optimisation, seeking to understand how these algorithms behave in everything from highly congested networks to free-flowing routes.
To do this effectively, they need realistic, data-driven travel times that could mirror the complexity of actual city movement — not just simplified distance models.
Why CRS4 Chose TravelTime
CRS4 turned to TravelTime to introduce accurate, scalable travel time data into their computational framework.
By using TravelTime’s real-world routing and multi-modal journey time data, CRS4 could incorporate stratified traffic datasets into their models, ensuring their simulations captured the nuances of urban mobility.
This integration enabled CRS4 to:
- Benchmark algorithm performance under realistic traffic conditions
- Test solver resilience across a full spectrum of city scenarios
- Evaluate how quantum and hybrid solvers scale under data-rich, time-sensitive environments
“By incorporating stratified traffic datasets into our optimisation framework, we've being able to test solver performance across diverse conditions, from congested urban scenarios to free-flowing routes, assessing if our algorithms are robust across the full spectrum of real-world situations.” - Giuliana Siddi Moreau, Senior Researcher, Quantum and High Performance Computing
