This research presents a method of comparing fixed-route transportation systems and demand-responsive feeder transit systems using passenger survey data, published transit schedules, and optimal routing techniques. Demand-responsive transportation can be utilized to improve transit service levels in low demand areas. Since cities can vary significantly in demand across the region and time of da...

Today’s business has inevitably been set in the global supply chain management environment. International transportation has never played such an important role in the global supply chain network, because movement of shipments from one country to another tends to be more frequent than ever before. This paper studies international transportation problems experienced by an international transport...

Indirect taxes on transportation activities that pollute can correct externalities and close the gaps between private and social costs. However, policy makers often find such Pigou taxes difficult to implement because of political resistance due to possibly adverse affects on equity. For this reason it is important to assess the distributional aspects of environmental levies. This article estim...

Chinese cities are experiencing major environmental e!ects from fossil fuel-based energy consumption for mainly residential and, increasingly, urban transportation uses. Community energy management (CEM) is a sustainable energy strategy which looks at how purposely shaping the built environment and designing urban services in consideration of energy production, distribution and use could a!ect ...

Today, along with enhancement of social well-being andeconomic development, demand for transportation is growing increasingly.Many countries are seeking for providing transportation servicesat a reasonable price. Therefore, optimization of carrying goods on nationalor international roads is highly important in terms of costs andtransportation indicator, so that the goods are shipped at minimumc...

Traffic jam in Malaysia is a huge and complicated problem nowadays, due to the rapid increase in the demand for transportation. This causes a longer vehicle travel times, increased energy consumption, growing environmental pollution, reduced traffic safety, and a decrease in the efficiency of transportation infrastructure. Hence, controlling the flow of traffic has become a very important issue...

This paper describes a declarative approach to modeling a multimodal transportation network (MTN) composed of multiple connecting transport modes, such as bus, tram, light rail, subway and commuter rail, where within each mode, service is provided on separate lines or routes. The considered model of a network of multimodal transportation processes (MTPN) provides a framework to address the need...

One of the core concepts in transport and economic geography states that transportation is a derived demand, both for passengers and freight transport alike. This assumption is reflected in the conventional literature which underlines that transport exists because it is the expression of a spatially differentiated function of supply and demand and is thus considered to be “derived” from other a...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the lead center for NASA's scientific and technical information. The NASA STI Program Office provides ...

We consider the applicability of the data from operators of cellular systems to modelling demand for transportation. While individual-level data may contain precise paths of movement, stringent privacy rules prohibit their use without consent. Presence data aggregate the individual-level data to information on the numbers of transactions at each base transceiver station (BTS) per each time peri...
