# The Role of Infrastructural and Psychological Factors in Sustainable Transportation Mode Choices
## 4 Discussion  
Our study shed light on the interrelation between five potential drivers and the general use of MIT as well as PT use. Interesting insights were found for infrastructural and psychological drivers. Travel durations between the residential location and the next station \begin{table}

Table 3: Ordinal logistic regression analysis to predict general public transportation use. show a connection to the use of MIT and PT. Shorter durations thereby contributed to the choice of a sustainable transport mode. Then again, travel durations between the residence and the city center were found to be valid predictors of MIT, but not of PT use. Longer travel durations led to a more frequent choice of MIT. We also investigated the role of three psychological variables, which have only partially been subject to prior investigations about travel mode choice. While trait adaptability was found to be a predictor for the general use of MIT (but not of PT), the CCP did not show any significant value within our models. However, the explanatory power of our models was limited to a moderate amount of variance, which should be considered when interpreting these findings. Our study confirmed findings on the attitude of car orientation, which reliably affected the MIT use as well as the use of PT. Lower values on adaptability and a higher car orientation predicted a higher use of MIT, and lower car orientation predicted a higher use of PT. When looking into the matter of sustainable transportation, the missing predictive value of CCP is also an interesting finding. The findings on the infrastructural factors are consistent with previous studies that have demonstrated the important role of proximity to PT facilities in promoting sustainable transportation choices [29; 33]. The finding that shorter walking times to stations predicted higher PT use aligns with the concept of transit-oriented development, which emphasizes the need for dense, mixed-use areas near transit hubs to promote ridership. However, the effect of proximity to stations on PT use is likely mediated by additional urban design factors, such as the pedestrian quality of access routes, land-use diversity in the vicinity of stations, and last-mile connectivity through feeder systems or micromobility options and can influence whether a short distance is perceived convenient and usable in practice [44]. The present results suggest that a reduction in walking time to major destinations is associated with a reduction in MIT use.
