Transportation planning is increasingly incorporating public participation, with Participatory Value Evaluation (PVE) emerging as a key method. However, the validity of PVE, particularly its face validity across different demographic groups, remains under-explored. This study addresses this gap by analyzing face validity evaluations from three recent PVE consultations in the Netherlands. Statistical analyses, content analysis, and expert discussions were employed to examine how factors such as age, gender, and education influence these evaluations. The findings indicate that while PVE is generally perceived positively, specific groups—particularly older adults and those with lower education levels—consistently evaluate its face validity negatively. To enhance the legitimacy of PVE in transportation planning, tailored strategies are recommended to address these persistent negative evaluations.
