Injury due to road traffic crash is a major cause of ill health and premature deaths in developing countries. Taxis provide a main mode of public transport in Vietnam but there has been little research on the risk of crash for taxi drivers. This retrospective study collected information on taxi crashes for the period 2006-2009 by interviewing drivers from five taxi companies in Hanoi, Vietnam, ...

Fuel efficiency has improved because of environmental policies and high gas prices. In most cases, increased vehicle usage is associated with negative outcomes because of potentially increasing emissions. In the New York City (NYC) taxi industry, however, increased vehicle usage corresponds to increased supply, which is meaningful because of limited the numbers of permissions and the fixed fare...

harm by either a driver or passenger of one vehicle directed against the occupants of another vehicle or pedestrians entail road rage and could potentially lead to involvement in collisions, injuries, and death.1-3 Road rage has also been associated with psychiatric illnesses in both the victims and the perpetrators.4 A previous study reported that the most common type of road rage experience o...

The leading economic explanation for tipping –that is, explanation why the practice is socially beneficial, not why individuals leave tips even though it is not narrowly advantageous to them– is that it confers an incentive to provide personal services. This fits many instances in which tipping is common but does not fit the taxicab business very well. We propose two novel explanations of tippi...

Government and regulatory agencies rely on the presentation of national and aggregate statistics to influence driver behaviour. The intention is, for instance, to illustrate the dangers of drink driving by publicising the number of road users who die annually from accidents involving alcohol abuse. These aggregate statistics often have only a limited impact on driver behaviour. Experimental stu...

The design of multi-agent based simulations (MABS) is up to now mainly done in laboratories and based on designers’ understanding of the activities to be simulated. Domain experts have little chance to directly validate agent behaviors. To fill this gap, we are investigating participatory methods of design, which allow users to participate in the design the pickup and delivery problem (PDP) in ...
