The impacts of household structure on the individual stochastic travel and out‐of‐home activity time budgets

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.

保障基本机动性的中央财政公交投入机理

中央财政公交投入不到位是中国城市公交优先发展面临的重要问题,加强中央财政资金投入、完善公交财政保障体系才能确保未来城市公交发展的可持续动力。提出保障公民基本机动性平等是中央政府支持城市公交发展的重要价值基准,从法理上为中央财政承担城市公交支出责任提供依据。从基本公共服务供给最低水平均等化的角度出发,提出中央财政公交投入资金额度的测算方法,为中央财政公交投入的科学决策提供了参考依据。以2010年为目标年进行案例分析,测算得到全国保障基本机动性的中央财政公交投入总额为150.1亿元。
