the demand for fossil fuel in the transport sector is constantly increasing and transportation is ranked amongst the highest greenhouse emitting sectors globally. today, tackling co2 emissions from road transport a widely discussed topic and constitutes a milestone towards reaching a sustainable, carbon neutral economy. this challenge is being described in various initiatives adopted in the eur...

Demand responsive transport (DRT), such as shared mini busses are an established form of public transport. Typically, these services operate in areas where demand is low (rural areas), very specific (airport shuttles), or only for certain user groups, such as persons with disabilities. With advances in communication technologies and possible driverless operations in the future, DRT systems may ...

approach of organic material anaerobic biodegradation and species of organic matter in sediment are discussed, and then a classifying method of the species is proposed on a new viewpoint. the pore water sediment oxygen demand (sod) numerical model in bottom sediment system is proposed originally, which differs from other advection-dispersion-sorption (ads) model in adding a sod-creating term. t...

This paper investigates transport services pricing problems faced by intermodal freight transport operators with fixed transport capacities in an intermodal freight transport network. We first present an optimal intermodal freight transport planning model to minimize the total transport cost. This model captures modality change phenomena, due time requirements, and the possibility to subcontrac...

Purpose In order for public transport to be a part of the solution to the environmental problems caused by traffic there need to be a clear understanding of how, and to what extent, different factors affect demand. There still seem to be some confusion regarding some key relationships, one of them being the effect of income on public transport demand. The purpose of this article is therefore to...
