The present research aims to assess public opinions on city-wide 30 km/h speed limits in Athens. Specifically, it seeks to identify the factors influencing acceptance of this policy measure, considering both perceptual aspects (e.g. beliefs about safety and congestion impacts, attitudes toward enforcement) and socio-demographic characteristics (e.g. age and gender). To achieve this objective, an online survey with targeted questions was conducted and data from 400 residents in Athens were collected and analysed. The sample was carefully balanced by gender and age to ensure it reflected the broader population. Respondents in Athens showed a generally favourable attitude toward the 30 km/h speed limit. Approximately 59% of participants expressed a positive opinion (somewhat positive and very positive), while around 22% expressed a negative opinion (somewhat negative and very negative). The remaining 20% of respondents reported a neutral stance. When examined by gender, both male and female respondents displayed broadly similar patterns of acceptance. However, females tended to express slightly higher levels of support, with a greater share selecting somewhat positive or very positive responses (32%) compared to males (26%). Conversely, men showed marginally higher shares in the somewhat negative and neutral categories. Results indicated a generally positive attitude among Athens residents toward the speed reduction initiative, with nearly six in ten respondents expressing supportive views. These results highlighted a broad recognition of the potential safety and environmental benefits associated with lower urban speed limits.
