Existing information systems for urban public transportation are empowering travelers to optimize their trips with respect to travel duration. Experience with such systems shows that this is a viable approach. However, we argue that solely relying on trip duration as the primary indicator for satisfaction can be limiting. Especially, in urban settings providing additional information such as th...

For many people in Australia, crowding is a major issue and an unavoidable aspect of their daily rail commute. Australian passenger experiences, perceptions of, and their reactions to crowding are not well understood. To gain an understanding of passenger perceptions and tolerance of railway crowding and the impact of passenger behaviour on the crowding experience, qualitative (Stage 1) and qua...

OBJECTIVES To describe the prevalence and correlates of safety belt and mobile phone usage in vehicles in the city of Barcelona (Spain). METHODS We performed a study using direct observation with a cross-sectional design. We selected 2,442 private cars, commercial vehicles, and taxis from all districts of Barcelona. RESULTS The prevalence of people not wearing safety belt was 10.5% among dr...

With proper management, Autonomous Mobilityon-Demand (AMoD) systems have great potential to satisfy urban population’s mobility demand by providing safe, convenient, and affordable ridesharing services. Meanwhile, such systems can substantially decrease private car ownership and use, and thus significantly reduce traffic congestion, energy consumption and carbon emissions. In order to schedule ...

In this work a full vehicle model of a rural transport vehicle (RTV) is developed in MADYMO. The steering, tier and suspension are modeled using standard modules available in the package. A speed controller was also incorporated to maintain a constant speed of the vehicle in the simulations. Validation of the model was done against experimental accelerations measured over a bump. The validated ...

In this paper we present a model of competition between operators on urban local bus routes in which passengers always board the first bus to arrive, and it is costly to revise timetables. The model predictds that timetables are unstable, the operator whose bus was boarded by fewest passengers is the most likely to change its arrival time, and to try to leapfrog its rival by arriving just befor...

This paper proposes the new speed control method of electric vehicles by generating the longitudinal speed pattern for improving the ride comfort against the longitudinal acceleration/deceleration. Since the longitudinal acceleration/ deceleration of EVs causes the discomfort of passengers, reducing such bad effect of acceleration/deceleration acting on passengers is very important for not only...

With a simple mathematical model, we explored the antiterrorist effectiveness of airport passenger prescreening systems. Supporters of these systems often emphasize the need to identify the most suspicious passengers, but they ignore the point that such identification does little good unless dangerous items can actually be detected. Critics often focus on terrorists’ ability to probe the system...

Participants were designated active drivers or passive passengers according to whether or not they had control over the displacements of a virtual vehicle, while taking 5, 10 or 15 tours of a virtual small town environment. When tested later, passive passengers were able to remember more landmarks than the active drivers. However, with successive tours, participants in both groups were able to ...

Traveling by air, especially long distance, is not a natural activity for humans. The combination of long flight duration, limited space, and an unusual cabin environment in terms of air pressure, humidity, and continuous noise causes physical and psychological discomfort and even stress for a large group of passengers. Excessive stress may cause some passengers to become aggressive and overrea...
