Background & Objective: Urban transportation is one of the fundamental aspects of urban quality of life, influencing both physical and mental health. In large cities such as Shiraz, different modes of mobility—public transit, private car, cycling, or walking—shape individuals’ daily experiences. This study aimed to examine the impact of various mobility modes on the mental health of citizens in Shiraz.
Methods: A descriptive-analytical survey was conducted with 395 Shiraz residents, selected through random sampling. Data were collected using questionnaires assessing mental health and urban transportation behaviors. Analyses included descriptive statistics, ANOVA, multiple regression, and Spearman correlation tests.
Results: Multiple regression results indicated that motorcycle use had a significant positive effect on mental health (β = 5.952, t = 4.134, P < 0.001), while other modes—including walking, cycling, private car (driver and passenger), and ride-sharing services—did not show statistically significant effects. ANOVA showed that mean mental health scores differed significantly among the transportation mode groups (F = 3.648, P = 0.002). Spearman correlation analyses revealed positive and significant relationships between monthly living expenses and mental health (r = 0.160, p = 0.001), perceived reliability of transportation modes and mental health (r = 0.246, p < 0.01), and perceived safety during travel and mental health (r = 0.256, p < 0.01). Exposure to travel delays and disruptions showed a very weak but significant positive correlation with mental health (r = 0.126, p = 0.013).
Conclusion: Transportation mode and the quality of travel experiences, including reliability and perceived safety, play a crucial role in citizens’ mental health. Promoting non-motorized transportation, improving infrastructure, and minimizing travel disruptions can enhance mental well-being and urban quality of life.
