The taxi industry: working conditions and health of drivers,a literature review

The taxi industry plays an important role in urban transportation systems, both in economic and mobility terms. In the case of the former, it provides employment for a large number of people and circulates significant amounts of money. In the case of the latter, it is a flexible means of transportation capable of arriving at any destination. Although the way the taxi industry is organised varies across countries and even within countries, some factors are shared at varying latitudes of the globe. Working conditions, habits, health, and exposure to road crashes have been a subject of interest for researchers from various disciplines, including medicine, psychology, and economics. However, much of this research focuses on a part of the problem and is not mutually referential. A review of the literature may be useful not only to researchers of diverse disciplines but also to industry representatives and those public officials responsible for transportation, road safety and health policy. This article provides a comprehensive review of the working conditions of taxi drivers, their relationship to road risk exposure and their consequences on the health of workers. It also includes information on coping strategies and protective behaviors. The review is based on a Scopus database search. The search covered the period from 1990 to 2015. This initial search was complemented with other database searches, which yielded some additional studies. Our goal was to summarise existing knowledge, identify possible lines of research and suggest some practical recommendations. It would be important (a) to reduce the workload, establish adequate time for breaks, and provide access to healthcare, (b) to implement actions to promote and maintain healthy habits, (c) to diagnose, detect and treat indicators of occupational fatigue and stress, and (d) to develop programs that make it possible to evaluate work concerns and broaden coping strategies to foster positive changes.     

Clarifying multiple-mode decision making in conventional psychological models: A consideration of the influential mechanism of car use's characteristics on the behavioral use of public transportation

The existence of the multiple-mode decision making process challenges the existing psychological theories those predict travel behaviors because the theories were mainly to explain the relationship between travelers' perceived attributes of a targeted mode, not to make choices between modes. A review of related literatures showed a lack of focus on the mechanism of one mode influencing other mode in psychological models. The present study investigates how car-related factors affect the establishment of bus use intention in a psychological investigation. It is hypothesized that single car use factors do not directly influence bus use intention, rather than that; they indirectly influence bus use intention through an overall factor of car use. Results from a dataset of 270 samples investigating three types of daily trips in the Japanese context showed support to the mediating effect of the overall car use factor. As such, an arbitrary inclusion of car-related factors to psychological models of public transportation may not be recommended.
