01

Key Findings

  • 01Accessibility was identified as the most critical criterion for service quality.
  • 02Availability, Security, Time, Customer care, Information, Comfort, and Environmental impact followed in importance.
  • 03The Full Consistency Method combined with a Rough Power Heronian aggregator provides a robust approach for group decision-making in service quality assessment.
02

Application

Design takeaway

When designing or improving rail transport services, rigorously investigate and prioritize the needs of users with disabilities, focusing first on ensuring accessibility and availability.

How to apply

Conduct user research with specific demographic groups to identify their most critical needs and use robust decision-making models to prioritize design interventions.

Project actions

  • 01Clearly define the target user group for your design project.
  • 02Use structured methods to gather and analyze user feedback on service quality.
03

Method & Evidence

AimTo develop and apply a novel model for defining the most critical service quality criteria in rail transport, with a specific focus on the needs of persons with disabilities.
MethodMulti-criteria decision-making (MCDM) using the Full Consistency Method and a Rough Power Heronian aggregator.
ProcedureA comprehensive survey identified 168 potential service quality criteria across Serbia. These criteria were then analyzed using the developed aggregation model to determine their relative importance from the perspective of users with disabilities.
Sample168 criteria were analyzed, with the user perspective implicitly represented by the criteria selection process.
ContextPublic passenger rail transport services.

Variables

IVService quality criteria (e.g., Accessibility, Availability, Security).
DVPerceived importance of service quality criteria by users with disabilities.
CVThe specific aggregation model used (Full Consistency Method and Rough Power Heronian aggregator), the geographical context (Serbia).
04

Strengths & Limitations

Strengths

  • +Employs a novel and rigorous multi-criteria decision-making approach.
  • +Focuses on a specific, often underserved, user group (persons with disabilities).

Limitations

The findings might be specific to the context of rail transport in Serbia and may not directly translate to other transport modes or regions without further investigation.

Reliability & validity

The reliability of the findings would depend on the consistency of user perceptions and the robustness of the aggregation method. Validity is enhanced by the focus on a specific user group and the systematic approach to criterion selection.

Think critically

How might the prioritization of criteria differ for other user groups, such as elderly individuals or parents with young children, and what methodologies could be employed to uncover these specific needs?

05

Design Principles

"Inclusive design requires a deep understanding of diverse user needs, with a focus on removing barriers and ensuring equitable access."

Understanding the unique needs and priorities of specific user groups, such as persons with disabilities, is crucial for developing inclusive and equitable services. This research provides a framework for systematically gathering and analyzing user feedback to inform design decisions that directly impact user experience and satisfaction.

06

What This Means for Your Design

When designing train services, especially for people with disabilities, make sure it's easy to get on and off trains and that services are actually available when they need them. These are the most important things.

Quick Cite

Paragraph starter

This research highlights the critical importance of user-centered design, particularly for vulnerable populations. The study by Dordević et al. (2019) demonstrates that for users with disabilities in rail transport, accessibility and availability are the most significant factors influencing service quality. This underscores the need for designers to prioritize inclusive design principles and conduct thorough user research to identify and address the most pressing needs of all potential users.
