FEDORA Scientific Publication: Urban Priority Pass: Fair signalised intersection management accounting for passenger needs through prioritisation

Fedora Project researchers have published “Urban Priority Pass: Fair signalised intersection management accounting for passenger needs through prioritisation” in Transportation Research Interdisciplinary Perspectives. The paper presents a reservation-based traffic prioritisation system designed to account for passenger urgency and improve fairness and efficiency in urban mobility systems. The research was authored by Kevin Riehl, Anastasios Kouvelas, and Michail A. Makridis.

 
 

Highlights

  • Introduces a reservation-based system for urban signal prioritisation.
  • Enables drivers to trade travel time based on urgency and willingness to pay.
  • Aligns mobility resources with individual needs while improving overall welfare.
  • Demonstrates equity and efficiency gains using an urban case study.
  • Shows large revenue potential for cities without new infrastructure

Abstract

Over the past few decades, efforts of road traffic management and practice have predominantly focused on maximising system efficiency and mitigating congestion from a system perspective. This efficiency-driven approach implies the equal treatment of all vehicles, which often overlooks individual user experiences, broader social impacts, the fact that users are heterogeneous in their urgency and that they experience different costs when being delayed. Even though they are the major bottleneck for traffic in cities, no dedicated instrument enables prioritisation of individual drivers at intersections. The Priority Pass is a reservation-based, economic controller that expedites entitled vehicles at signalised intersections, without causing arbitrary delays for non-entitled vehicles and without affecting transportation efficiency de trop. Particularly applicable to large, congested cities with rich sensor infrastructure, the prioritisation of vulnerable road users, emergency vehicles, commercial taxi and delivery drivers, or urgent individuals, this approach can enhance road safety, and achieve social, environmental, and economic goals. A case study of Manhattan demonstrates the feasibility of individual prioritisation (up to 40% delay reduction), and quantifies the potential of the Priority Pass to gain social welfare benefits for the people. A market for prioritisation could generate up to $ 1 million in daily revenue for Manhattan, and equitably allocate delay reductions to those in need. The findings provide a foundation for integrating user-centric prioritisation mechanisms into emerging smart city traffic management systems, supporting data-driven policymaking and equitable mobility planning.

FEDORA Scientific Publication: Quantitative fairness—A framework for the design of equitable cybernetic societies

 

Researchers within the Fedora Project have published a new paper titled “Quantitative fairness—A framework for the design of equitable cybernetic societies” in Computers in Human Behavior: Artificial Humans. The publication explores quantitative approaches to fairness in cybernetic and algorithmic systems, with a focus on equitable decision-making, transparency, and socially feasible resource allocation frameworks. The paper was authored by Kevin Riehl, Anastasios Kouvelas, and Michail A. Makridis.

 

Highlights

  • Quantitative basis for fairness in cybernetic and algorithmic systems.
  • Unified framework linking distributive, procedural, and algorithmic fairness.
  • Bridges engineering, economics, and social science fairness concepts
  • Tools for designing and evaluating fair decision-making algorithms
  • Case studies show trade-offs between equality, efficiency, and fairness

Abstract

Advancements in computer science, artificial intelligence, and control systems have catalyzed the emergence of cybernetic societies, where algorithms play a pivotal role in decision-making processes shaping nearly every aspect of human life. Automated decision-making for resource allocation has expanded into industry, government processes, critical infrastructures, and even determines the very fabric of social interactions and communication. While these systems promise greater efficiency and reduced corruption, misspecified cybernetic mechanisms harbor the threat for reinforcing inequities, discrimination, and even dystopian or totalitarian structures. Fairness thus becomes a crucial component in the design of cybernetic systems, to promote cooperation between selfish individuals, to achieve better outcomes at the system level, to confront public resistance, to gain trust and acceptance for rules and institutions, to perforate self-reinforcing cycles of poverty through social mobility, to incentivize motivation, contribution and satisfaction of people through inclusion, to increase social-cohesion in groups, and ultimately to improve life quality. Quantitative descriptions of fairness are crucial to reflect equity into algorithms, but only few works in the fairness literature offer such measures; the existing quantitative measures in the literature are either too application-specific, suffer from undesirable characteristics, or are not ideology-agnostic. This study proposes a quantitative, transactional, and distributive fairness framework based on an interdisciplinary foundation that supports the systematic design of socially-feasible decision-making systems. Moreover, it emphasizes the importance of fairness and transparency when designing algorithms for equitable, cybernetic societies, and establishes a connection between fairness literature and resource allocating systems.

TRA 2026 – Re-generation in Transport

Transport Research Arena (TRA) is Europe’s largest and most prestigious conference on transport research and innovation, organized every two years by the European Commission and leading professional partners. 

TRA brings together researchers, industry experts, policymakers, and civil society representatives to explore new solutions for the future of sustainable and smart mobility. It is where ideas meet action and where Europe’s transport community comes together to shape tomorrow’s systems and technologies.

FEDORA will be featured during the conference with several activities:
