Quantification of the value of time (VOT) is important for measurement of the benefit of transportation projects in terms of travel time savings. In Japan, VOT is considered higher on weekends than on weekdays because on the weekend people have limited time to allocate to discretionary activities that are not normally done on weekdays, such as family care-related activities. In Indonesia, a culturally diverse country, providers and users seem to have different perceptions of VOT. A method of analyzing the value of activity time is presented. It argues that the benefit of travel time saving should be evaluated in more detail on weekends by considering the value of discretionary activities to explain these phenomena theoretically. Activity diary surveys were conducted in Tokyo, Japan, and Jakarta, Indonesia, to verify the influence of psychological needs on people's holiday activities. Finally, a time allocation model that uses the revealed preference data and a marginal activity choice model that uses stated preference data are proposed to calculate the value of activity time. The theories underpinning these models are Maslow's psychological needs, consumer theory in economics, and a discrete choice model. The empirical results show that an individual's priority of needs influences time allocation. In particular, the results show that in Tokyo, spending time with family on weekends is more valuable than other types of activities, while in Indonesia the value of spending time with family exceeds that of work time even on weekdays.

Securing the well-being, protection of human rights and equality on the ground of age, gender, race, nationality etc along with sustainable economic development becomes the most important goal for any country. Gender differences in labor market are a problem of many countries. Being a larger demographic group, women have played a vital role in employment and economic development. Despite longstanding striving for gender equality, the inequality manifests itself in labor markets around the world. There is no common opinion on the reasons of the existence of gender differences in economic literature. After decades of research most investigators would agree that there can be no single-factor explanation for gender inequality in the labor market. One of the conventional explanations of gender gap in employment sphere includes the differences in men’s and women’s preferences in working hours due their stereotypical roles in the private and public life. This paper is focused on the study of gender feature of time allocation and its impact on the labor supply by men and women. For this purpose, based on the different types of activity, particular: income getting or in­co­me increasing promote activity, non-monetary inco­me obtain activity, income-make activity, non-income-make activity, indirect-receipts activity, the author introduces the time allocation model which includes parameters such as working time, leisure, non-working time, using time, free time and time for satisfying an individual’s physiological needs. For the attribution of different types of practice to certain kinds of activity the “principle of dominant purpose of activity” was offered. According to given time allocation model, the  pattern of features of labor supply by men and women is offered in the paper.

The problem of multiple necessities and limited funds is common in the transportation field. Funding allocation for a transportation agency often involves prioritizing the allocation of funds across a number of participants who have their own needs and preferences. If a participant believes that the final allocation is unfair, then this perception could result in the generation of envy. In this paper, a genetic optimization technique is applied to a Fair Division Transportation Funding Allocation Model (FDTFAM) to minimize the total envy based on the participant’s own priorities and the budget constraints.

Driver behavior under congestion pricing is analyzed to evaluate the effects of alternative congestion pricing schemes. The analysis, which is based on stated preference survey results, focuses on time allocation, departure time choice, and route choice when a congestion pricing scheme is implemented on toll roads in Japan. A unique feature of the model system of this study is that departure time choice and route choice are analyzed in conjunction with the activities before and after the trip. A time allocation model is developed to describe departure time choice, and a route and departure time choice model is developed as a multinomial logit model with alternatives representing the choice between freeways and surface streets and, for departure time, the choice from among before, during, or after the period when congestion pricing is in effect. The results of the empirical analysis suggest that departing during the congestion pricing period tends to have higher utilities and that a worker and a nonworker have quite different utility functions. The comparative analysis of different congestion pricing schemes is carried out based on the estimated parameters. The results suggest that the probability of choosing each alternative is stable even if the length of the congestion pricing period changes, but a higher congestion price causes more drivers to change the departure time to before the congestion pricing period.
