Journal of Turkish Operations Management · 2024

Key Findings

01Traffic congestion, infrastructure, and aesthetics are the most prominent factors for public transport sustainability.
02Air pollution, infrastructure, accident damage, affordability, and aesthetics are significant causal factors.
03Traffic congestion, accessibility, and human health impact are primarily effect factors.
04While environmental factors like air pollution are significant causal factors, their perceived importance may be underestimated.

Application

Design takeaway

How to apply

When evaluating the sustainability of any public transport system, use a structured approach like DEMATEL to map the relationships between factors and identify the most impactful areas for improvement.

Project actions

01When researching a design problem, consider using analytical tools to understand the relationships between different factors.
02Ensure your design solutions address the root causes of problems, not just the symptoms.

Method & Evidence

AimTo identify and prioritize the key factors influencing the sustainability of public transportation systems in urban settings using a decision-making framework.

MethodDecision-Making Trial and Evaluation Laboratory (DEMATEL) analysis

ProcedureA framework of public transportation sustainability factors was developed, and a DEMATEL-based multi-criteria decision analysis approach was applied to evaluate these factors in the context of Pakistan's Twin Cities. A sensitivity analysis was conducted across six scenarios.

ContextPublic transportation systems in urban environments, specifically the Twin Cities of Pakistan.

Variables

IV["Traffic congestion","Infrastructure","Aesthetics","Air pollution","Accident damage","Affordability"]

DV["Public transport sustainability"]

CV["Urban context (Twin Cities of Pakistan)","Public transportation system characteristics"]

Strengths & Limitations

Strengths

+Employs a robust analytical method (DEMATEL) for complex decision-making.
+Provides a structured approach to understanding interdependencies between sustainability factors.

Limitations

The specific factors and their importance might vary significantly in different countries or cities. The DEMATEL method relies on expert judgment, which can be subjective.

Reliability & validity

The reliability of the DEMATEL method depends on the consistency of expert judgments. Validity is enhanced by the sensitivity analysis, which tests the robustness of the findings under different scenarios.

Think critically

How might the perceived importance of factors like air pollution change in cities with more stringent environmental regulations or higher public awareness of climate change?

Design Principles

"Prioritize interventions that address primary causal factors in complex systems to achieve the greatest impact on desired outcomes."

Understanding the causal relationships between various factors influencing public transport sustainability allows designers and urban planners to prioritize interventions. Focusing on high-impact drivers like congestion and infrastructure can lead to more effective and efficient improvements in the overall sustainability of urban mobility.

What This Means for Your Design

To make public transport better for the environment and people, we need to focus on making traffic less jammed and building better stations and vehicles.

How to use in your project

1.Use the findings to justify the focus of your design project on specific aspects of public transport sustainability, such as traffic flow or infrastructure design.
