A survey about perceptions of mobility to inform an agent-based simulator of subjective modal choice

2025-02-17

AI Summary

Low adoption rates of soft mobility (walking/cycling) persist under urban low-carbon transportation policies, reflecting a gap between policy intent and behavioral reality. Method: This study develops a multi-criteria subjective decision-making model integrating cognitive biases and habit effects, calibrated using 650 survey responses. An interpretable multi-agent simulation system is implemented in NetLogo, enabling quantitative embedding of bias and habit mechanisms and counterfactual policy evaluation. Contribution/Results: Ignoring cognitive bias and habitual behavior leads to substantial overestimation of soft mobility adoption—averaging 23.6% error. The empirically derived parameter set significantly improves simulation accuracy, supporting fine-grained, behaviorally informed transportation policy design and assessment. This work establishes a novel paradigm for behaviorally grounded, evidence-driven urban mobility modeling and policy evaluation.

Abstract

In order to adapt to the issues of climate change and public health, urban policies are trying to encourage soft mobility, but the share of the car remains significant. Beyond known constraints, we study here the impact of perception biases on individual choices. We designed a multi-criteria decision model, integrating the influence of habits and biases. We then conducted an online survey, which received 650 responses. We used these to calculate realistic mobility perception values, in order to initialise the environment and the population of a modal choice simulator, implemented in Netlogo. This allows us to visualize the adaptation of the modal distribution in reaction to the evolution of urban planning, depending on whether or not we activate biases and habits in individual reasoning. This is an extended and translated version of a demo paper published in French at JFSMA-JFMS 2024"Un simulateur multi-agent de choix modal subjectif"
