3.2. Analysis of Gender Difference in Travel Mode Choice for Daily Commuting Trips
The difference in travel mode choice of women and men over 16 years old who participated in the MoTiV data collection campaign was analyzed using the MNL regression model in R Software. The travel mode choice was estimated using the maximum likelihood (ML) method. In this study four transport mode categories are used for female and male travelers’ mode choice modeling: (1) private motorized vehicle as a driver; (2) private motorized vehicle as a passenger; (3) public transport; (4) walking as an active mode. The cycling and micro-mobility transport category is set as the reference alternative. Thus, as a reference alternative, the utility of “using bicycle and micro-mobility services” is set to zero.
The pseudo-R-square values as goodness-of-fit measures for the assessment of the models’ quality together with the estimated
p-value for each model have been presented in
Table 1.
All statistically significant predictors resulting from the models for males and females in every transport category are shown in
Figure 10 and
Table 2. The estimated results of MNL are also presented in
Table A4 (see
Appendix A). The model results (
Figure 10 and
Table 2) indicate that similar factors influence the choice of means of transport for both males and females. Detailed differences for every transport category are described below.
In terms of traveler characteristics, the results allude that the older females and males are more interested in using this transport category than in cycling and using micro-mobility modes of transport (
Table 2). Interestingly, in the case of urban size, the bigger city female dwellers are more likely interested in traveling as car drivers, on the contrary, male dwellers are less interested.
The models’ results also show that all trip purposes at the destination significantly impact the choice of this transport category (
Figure 10). Females are less likely to travel by car as a driver than traveling by bicycle or micro-mobility systems for all these trip purposes. It also applies to males, except for the reason to pick up or drop off someone. In that case, they prefer to drive a car. A significantly positive impact on choosing this travel category in comparison to cycling and emerging micro-mobility by females and males was also identified for trip characteristics such as trip frequency, a day of the week and time of day. It is evident from the results that women would rather choose private motorized vehicles as a driver during weekends instead of bicycles or micro-mobility compared to men. Moreover, results also demonstrate that traveling during off-peak hours and late evening most likely increases the probability of using private motorized vehicles as a driver by women with access to a private car more than by men.
According to the estimated results, a significant influence of travel activities on the choice of private motorized transport mode as a driver was also ascertained. During travel, males who are willing to browse the Internet or listen to music are more likely to choose this travel category rather than those traveling by bicycle and micro-mobility devices. In the case of females, listening to music and reading electronic devices would also increase the propensity of using a car as a driver. Several experience factors also have a positive effect on the choice of this transport category. Vehicle quality, seat comfort, privacy, security, and safety are among those with the biggest impact. It means that males and females who consider these experience factors either as positive or negative factors influencing their travel experience are more likely to use a car as a driver than a bicycle or emerging mobility services.
The results also indicate that females with better mood resulting from the trips are more likely to choose travel by car as a driver rather than a bicycle. On the contrary, males with better mood are more interested in cycling than driving a car. The exact opposite applies to the worthwhileness of their travel time. The more men consider their travel time to be worthwhile, the more likely they are to travel by car as a driver than by a bicycle, and vice versa, the more women consider their travel time to be more worthwhile, less likely they will choose this category than cycling. In terms of the type of perceived value of travel time, the results show that females and males who tend to rate their trips as productive, whether in terms of personal tasks or paid work are more likely to choose traveling by car as a driver than traveling by bicycle and micro-mobility devices. As expected, people who consider their trips as fitness trips (being able to do exercise) are more likely to choose cycling than driving a car. In case of enjoyment as a gained subjective value, results, surprisingly, indicate that women are more likely perceive enjoyment as a positive influencing value for travel time worthwhileness when using a car as a driver than a bicycle, which is in contrast to male travelers’ perception of value of travel time.
In terms of weather, the significant impact on choosing this transport category was identified for both, men and women. The females and males would be more likely to choose this means of traveling rather than cycling and emerging micro-mobility in windy, rainy and cold weather. On the contrary, they would less likely select this transport mode in neutral and cloudy weather over the use of bicycle or micro-mobility services. Interestingly, the results also indicate that females would be much more interested in this transport mode in rainy weather rather than males.
According to the estimated results, age was identified as a negative factor influencing the choice of this transport category for both women and men. It means younger people are more interested to use a different type of private and shared motorized transport system as a passenger rather than bicycle or micro-mobility services. In addition, the urban size was also identified as a significant factor with an impact on female traveler choice of this transport mode. The results indicate that women residing in smaller urban areas are less interested in using private motorized vehicles as passengers compared with cycling and other micro-mobility services.
Regarding trip characteristics, all trip purposes have significant negative impact on choosing this transport category compared to cycling and micro-mobility services, which can also be interpreted as the low tendency of both male and female travelers for ride sharing. Trip duration and trip frequency positively influence choosing traveling as a passenger of private motorized vehicle. For instance, women who make the reported trip more often are most likely to be interested to choose being a car passenger over riding bicycle or micro-mobility systems. For females, it was also found that travel time flexibility negatively affects choosing this transport category which means women with time constraint for arriving at the destination would most probably choose less private motorized vehicles as a passenger compared to bicycle and micro-mobility services for their daily trips. The results further confirmed that men and women who prefer to browse the Internet while traveling or listening to music are willing to travel by car rather than bicycle. The positive impact on choosing this travel category was also identified for activity reading an electronic device. Men who read during their trips are more willing to travel by car as a passenger. Concerning experience factors, the biggest positive significant impact was identified in the case of females for traffic congestion, vehicle quality, and then seat comfort, security, safety, and privacy. Interest in traveling by car as a passenger with respect to cycling is higher for males who consider seat comfort and privacy as important factors for their travel mode choice.
Worthwhileness rating and perceived mood were identified as significant factors for both genders. The results indicate that females whose feelings derived from travel experience were better, (i.e., emotionally happier) are more likely to choose traveling by car as a passenger than cycling, but on the contrary, men are less interested. In the case of evaluation of travel time worthwhileness, a higher travel time worthwhileness rating negatively influence the tendency for choosing this transport category. In a comparative investigation, it can be argued that both female and male travelers with a higher perception of gained WTT values for productivity and enjoyment would most likely rather use private and shared motorized transport services rather than driving a car. According to the result, it can be also asserted that people with a higher positive fitness value assessment of travel time, would be less interested in choosing this category.
Concerning the weather condition as an influencing determinant, it was found that neutral and cloudy weather conditions have a significant negative impact on choosing this travel category for both females and males. Cold weather also negatively influences the interest of males in traveling by car or motorbike as passengers. On the contrary, windy weather has a significant positive impact on choosing this category.
As can be seen in
Table A4, for both men and women increasing age will most probably degrade their willingness in choosing public transport rather than cycling and emerging micro-mobility systems. Therefore, it can be interpreted that being an old woman would decrease the likelihood of using public transport, which is in line with the findings from Tyrinopoulos and Antoniou [
49]. In a similar vein, it also applies to the impact of the urban size in which respondents live there. For instance, both women and people living in metropolitan or medium-size urban areas would rather use less public transport in case of having a choice of using bicycle or micro-mobility systems. For the trip purposes, work-related and business trips were identified as significant factors for both men’s and women’s choice of public transport. It means that females are more likely to choose public transport than cycling and emerging micro-mobility when traveling for work-related trips and when are on a business trip. Not surprisingly, results also indicate that women are more willing to use public transport for daily shopping than men. In view of other trip characteristics, it was found that increasing trip duration negatively influences females’ interest in public transport and positively males’ tendency. Travel time flexibility, trip frequency, day of the week, and time of the day were also realized to be significant influencing factors for females for choosing public transport instead of cycling positively. For males, travel time flexibility and trip frequency also positively impact choosing public transport, while the occurrence of trips during weekends could negatively influence their choice of public transport.
According to estimated results, all travel activities for both men and women were identified as positively significant for a public transport mode choice. Based on the model’s results, it can be seen that even in the case of experience factors, it is not possible to observe large differences between men and women. However, more significant factors have been identified for women, but those with the highest coefficients are the same as for men: privacy, security and safety, road quality, crowdedness/seating availability, seating quality, and payment and tickets. All these determinants positively influence travelers’ tendency for using public transport rather than cycling.
Model results also point out that the more positive the men feel about the trip, the less interested they would be in traveling by public transport. On the contrary, with increasing travel time worthwhileness assessment, the likelihood of using public transport would raise among male travelers. In the case of women, those who have a higher perception of usefulness (i.e., worthwhileness) of their travel time, and happier feelings about their trip, in general, would be less interested in traveling by public transport. While in the case of men, those who perceived higher WTT would be more willing to use public transport for their daily trips.
Regarding the influence of weather conditions, both females and males would most probably choose public transport instead of cycling and emerging micro-mobility in windy weather and females in cold and neutral weather conditions. On the contrary, a lack of interest in public transport arises in the case of cloudy weather for both female and male travelers.
The model results for walking as an active mode demonstrate that with the increasing age of men, their interest in this category also increases compared to cycling in smaller urban areas, and this is also the case in urban sizes. Conversely, in the larger urban areas (metropolitan and medium-sized cities), women would be more interested in traveling on foot.
In regard to the effect of trip characteristics impacting people’s decision on choosing walking, all variables were identified as significant. Furthermore, results also reflect that people would choose cycling instead of walking for all trip purposes.
A negative impact on this category in both genders was also found in the case of trip duration, travel time flexibility, and time of day. The difference between men and women was only in the case of the day of the week when women would choose walking more likely than cycling during weekends, while men conversely would rather use bicycle or micro-mobility means of transport during weekends.
The results show that women and men who consider their travel time more worthwhile are more interested in walking than cycling. In a similar vein, it also applies to the perceived mood in the case of women. It can also be seen that people who prefer to enjoy their travel time or be able to do exercise would more likely use cycling than walking. In terms of conducting activities during travel, results elucidate that people who listen to music or browse the Internet would prefer to travel on foot rather than by bicycle. The identified significant experience factors partly differ between men and women. In the case of women that negatively affects their interest in walking, such as the difficulty of the route, other cars and vehicles, road path quality, and road path directness. Conversely, air quality, scenery, ability to do what is wanted, ability to take kids, reliability of travel time, road path availability and safety, and other people all affect the decision to walk instead of use bicycle and micro-mobility systems.
Regarding the influence of weather on walking as a travel mode, model findings indicate that the weather conditions negatively affect the choice of this mode for both genders in neutral and cloudy weather while for windy or rainy weather conditions, people would prefer to walk instead of using bicycles or micro-mobility services. The only significant difference between males and females was found for the case of cold weather in which females choose to walk rather than cycle in contrast with males’ tendency for choosing bicycle or micro-mobility systems.
