Understanding the socio-psychological mechanisms that determine the public acceptability of road pricing could be a key for its implementation in urban environments where this is a viable scenario. Studying the attitudes of older people is of particular importance due to the aging of the populations in the industrialized democracies, the high political engagement of older people, and their vulnerability to transport-related social exclusion. Research by the present authors had previously identified that older people's beliefs about what is the normal, acceptable, or even expected choice in a particular social context (“social norms”) and their tendency to favor, more than any other age group, what is positively valued by society (“pro-social value orientation”) affect their attitudes to road pricing. The present paper aims to develop an in-depth understanding of these attitude-shaping determinants drawing on the findings of focus groups conducted in Bristol, UK. The findings suggest that there are three distinctive expressions of pro-sociality: pro-environmental values and generativity on the one hand, these two being drivers of support for road pricing, and pro-equity values on the other, which tend to drive opposition. Social norms have two particular expressions: subjective norms (i.e. norms reflecting people’s immediate social environment) and norms referring to others and society in general. Furthermore, a theory-driven thematic analysis indicates that trust in the integrity of the concept and older age as a life stage associated with aging, retirement, lower income, mobility barriers and deteriorating health are important in how attitudes reflecting and affecting public acceptability to road pricing form

The amount of time individuals and households spend in travelling and in out-of-door-activities can be seen as a result of complex daily interactions between household members, influenced by opportunities and constraints which vary from day to day. Extending the deterministic concept of travel time budget to a stochastic term, and applying a Stochastic Frontier Model to a dataset from the 2004 UK National Travel Survey, this study examines the hidden stochastic limit and the variations of the individual and household travel time and out-of-home activity duration– concepts associated with travel time budget. The results show that most individuals may not have reached the limit of their ability to travel and may still be able to spend further time in travel activities. The analysis of the model outcomes and distribution tests show that among a range of employment statuses, only full-time workers’ out-of-home time expenditure has reached its limit. Also observed is the effect of having children in the household: children reduce the flexibility of hidden constraints of adult household members’ out-of-home time, thus reducing their ability to be further engaged with out-of-home activities. Even when out-of-home trips are taken into account in the analysis, the model shows that the dependent children’s in-home responsibility reduces the ability of an individual to travel to and to be engaged with out-of-home activities. This study also suggests that, compared with the individual travel time spent, the individual out-of-home time expenditure may perform as a better budget indicator in drawing the constraints of individual space-time prisms.

Pedestrians are exposed to risks when crossing roads in urban areas. The crossing behaviour of pedestrians was studied as a factor contributing to their exposure to risks on the road and to their involvement in road accidents. This work explores two specific aspects of crossing behaviour: crossing speed and head pitches – the proportion of time pedestrians point their heads down (rather than towards the traffic) when crossing a road. The last one is used as an indicator of the (lack of) attention to cross-traffic. We also explored the possible effect of fear of falling (FOF) among pedestrians, as it might be associated with slow walking, less attention to cross traffic, and more attention to the pavement and their footsteps. This paper reports on a field study that combined an observatory technique with short survey. 203 pedestrians in two sites (signalised and unsignalised crosswalks) were video recorded while crossing the road. The FOF of pedestrians and other measures of pedestrian behaviour at crosswalks were revealed by means of questionnaire. Age and gender had the most significant effects on crossing speed, and FOF had a significant effect on the proportion of downward head pitches during crossing.
