The raison d’etre for the air transportation system is the movement of passengers and cargo. Consumer information for airline passengers and regulatory consumer protection of airline services provide measures of performance using the percentage of on-time flights, and the percentage of cancelled flights. Researchers have shown that these “flight-based” metrics are a poor proxy for measuring the...

The importance of computer applications and telecommunication services relying on ee-cient multi-destination communication is growing rapidly. It is now likely that a signiicant portion of the overall traac in future communication environments will be of the multi-destination type. At the same time, lightwave technology is emerging as a promising candidate for implementing the next generation o...

SOURCES OF DATA Literature review through the LILACS and MEDLINE(®) databases, using the terms: travel, safety, protective equipment, child, preventive medicine, retrieving articles published in the last 21 years. SUMMARY OF THE FINDINGS The authors a...

Searching for optimal ways in a network is an important task in multiple application areas such as social networks, co-citation graphs or road networks. In the majority of applications, each edge in a network is associated with a certain cost and an optimal way minimizes the cost while fulfilling a certain property, e.g connecting a start and a destination node. In this paper, we want to extend...

2 ABSTRACT The quantification of the freight movements occurring in each traffic zone, and then of the Origin-Destination trip tables due to the delivery of goods in the urban environment, is essential for evaluating the effects of any city logistic policy in terms of vehicle congestion and polluting emissions, based on the assignment of demand flows to the road network. To this end in the pres...

When mobiTopp was initially designed, more than 10 years ago, it has been the first travel demand simulation model intended for an analysis period of one week. However, the first version supported only an analysis period of one day. This paper describes the lessons learned while extending the simulation period from one day to one week. One important issue is ensuring realistic start times of ac...

A mobile ad hoc network (MANET) is characterized by multi-hop wireless links in the absence of cellular infrastructure and frequent host mobility. In this paper, a new on-demand routing protocol is proposed, named on-demand routing protocol with backtracking (ORB), for multi-hop mobile ad hoc networks. Suppose a source host wants to deliver a message to a destination in a MANET. First, the sour...
