Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

To maximize their impact, socially responsible households can invest responsibly (SRI), consume (SRC), or do both. The key question of this paper is, which mix SRI and SRC leads to a desired impact with the lowest loss utility for households. In closed micro-economic model, we show that both strategies yield symmetric proportional behavior. For individual household, however, one strategy domina...

BACKGROUND Identifying women with poor access to health services may inform strategies for improving maternal and child health outcomes. The aim of this study was to explore risk factors associated with access to health facilities (in terms of physical distance) among women of reproductive age (15-49 years) in Dabat district, a rural area of north-western Ethiopia. METHODS A randomly selected...

This paper aims to introduce a new modelling approach that represents departure time, destination and travel mode choice under a unified framework. Through it, it is possible to overcome shortages of the traditional 4-step model associated with the lack of introducing actual travellers’ behaviours. This objective can be achieved through adopting discrete 3-level Nested Logit model that represen...

[1] In this study, we evaluate the use of ground‐penetrating radar (GPR) to investigate the effects of bacterial activity in water saturated sand. A 90‐day laboratory‐scale controlled experiment was conducted in a flow‐through polycarbonate sandbox using groundwater from the Kansas River alluvial aquifer as inoculum. After 40 days of collecting baseline data, bacterial growth was stimulated in ...

Shippers and motor carriers are impacted by and react differently to travel time variability due to their positions within the supply chain and end goals. Through interviews and focus groups these differences have been further examined. Shippers, defined here as entities that send or receive goods, but do not provide the transportation themselves, are most often concerned with longer-term disru...
