There is growing interest in transportation pricing reforms to help achieve various planning objectives such as congestion, accident and emission reductions. Their effectiveness is affected by the price sensitivity of transport, that is, the degree that prices affect travel activity, measured as elasticities (percentage change in travel caused by a one-percent price change). Lower elasticities ...

Here it is presented an application that plans out travel on public transports and that chooses the best ones, according to preference criteria provided by the user. These criteria are: the time spent on the travel, the price of the tickets and the quality of the transports. The application combines different means of transport. Algorithms and heuristics were developed to draw up transport plan...

The empirical evidence shows that travel time is crucial for rail transport to be a competitor to air transport. However, there are no papers testing whether travel time has a direct effect on airline pricing. This paper is a step towards filling this gap. We test and quantify the effect of rail travel time on airline fares, using unique data at flight-level. We find that airlines design pricin...

BACKGROUND The presence and mix of destinations is an important aspect of the built environment that may encourage or discourage physical activity. This study examined the association between the proximity and mix of neighbourhood destinations and physical activity. METHODS Secondary analysis was undertaken on physical activity data from Western Australian adults (n=1394). These data were lin...

Values of travel time savings are often used in cost-benefit analysis of transport projects and policies, and also to compute generalised travel costs. There has been considerable debate as to whether different research methods (e.g. stated versus revealed preference) will lead to different values of travel time savings, and which segmentations (e.g. by income or mode) are most important to cap...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

Much recent public health research has emphasised the health impacts for young people of 'active travel' modes, typically defined as walking and cycling. Less research has focused on public transport modes. Drawing on qualitative data, we examine the links between bus travel and wellbeing in London, where young people currently have free bus travel. Our findings indicate that bus travel can be ...

Microtubule-based molecular motors often work in small groups to transport cargos in cells. A key question in understanding transport (and its regulation in vivo) is to identify the sensitivity of multiple-motor-based motion to various single molecule properties. Whereas both single-motor travel distance and microtubule binding rate have been demonstrated to contribute to cargo travel, the role...
