This paper discusses the use of the Policy Based Network paradigm, COPS (Common Open Policy Service) and NSIS (Next Steps In Signalling) frameworks being developed by the IETF, in the context of the European Project EuQoS (End-to-End Quality of Service over Heterogeneous Networks). An overview of the EuQoS architecture is provided followed by the analysis of the use of PBN/COPS and NSIS to supp...

Air travel is becoming increasingly more accessible to people both through the availability of cheap flights and because the airlines are now able to cater for individuals of all ages and disabilities. Air travels, especially for long haul, may cause both physiological and psychological discomfort to passenger. Passenger comfort is clearly a main factor in user’s acceptance of transportation sy...

The prediction of travel time is challenging given the sparseness of real-time traffic data and the uncertainty of travel, because it is influenced by multiple factors on the congested urban road networks. In our paper, we propose a three-layer neural network from big probe vehicles data incorporating multi-factors to estimate travel time. The procedure includes the following three steps. First...

We study the starvation of a lattice random walker in which each site initially contains one food unit and the walker can travel S steps without food before starving. When the walker encounters food, it is completely eaten, and the walker can again travel S steps without food before starving. When the walker hits an empty site, the time until the walker starves decreases by 1. In spatial dimens...

The COVID-19 pandemic has extremely affected several industries including international travel and tourism. Many scholars have tried to describe the cause-effects of this major phenomenon. This study majorly aims explore relationship between risk perception intention where stress level prone quarantine serves as a moderating factor. researchers believed that influence dimensions social risk, ps...

When considering the sharp growth rate of use e-micromobility vehicles, such as e-scooters and e-bikes, it is necessary to investigate whether these emerging modes transport play a sustainable role in cities terms their energy efficiency, emissions, relationship with other mobility, public transport. This paper aims provide comprehensive overview impacts through systematic review relevant studi...

This article aims at identifying the factors involved in affecting the travel demand to Iran. The hypothesis of the research specifies the variable of “domestic social unrest and insecurity” as the most significant obstacle that stands against an expansion of the demand for travel to Iran. To test the above hypothesis, first several demand models that have been proposed to study demand for tour...
