Recently, path flow estimators (PFE) have been used for the estimation of origin–destination (O–D) matrices. This paper develops a formulation that incorporates a decoupled path flow estimator in a generalized least squares (GLS) framework. The approach seeks to solve a GLS problem that minimizes the sum of errors in traffic counts and O–D matrices based on an equilibrium assignment mapping der...

We consider a cooperative wireless network comprised of a source, a destination and multiple relays operating in the presence of an eavesdropper, which attempts to tap the source-destination transmission. We propose multi-relay selection scheme for protecting the source against eavesdropping. More specifically, multi-relay selection allows multiple relays to simultaneously forward the source’s ...

Path flow estimator ~PFE! is a one-stage network observer proposed in the transportation literature to estimate path flows and path travel times from traffic counts in a transportation network. The estimated path flows can further be aggregated to obtain the origin–destination sO–Dd flows, which are usually required in many transportation applications. In this paper, we examine the capability o...

This paper presents a system proposing a solution to the problem of Origin-Destination (OD) trip modelling for Multimodal Transportation Networks (MTN) using GIS tools. An efficient method for the handling of travel information within the MTN consists of dealing with an optimal multimodal routing of travellers from a point of origin to point of destination. Furthermore, the multimodal travellin...

The shuttle service in tourism depends on physical accessibility of a destination, on movement within the destination and the transport itself. In today’s world, transport is not just the act of getting to a wanted destination. Moreover, travelling by a certain vehicle can be a tourist attraction, if the transportation means is designed to arouse the feeling of joy and excitement. The purpose o...

In recent years, there has been increasing attention on bicycle-sharing systems (BSS) as a viable and sustainable mode of transportation for short trips. However, due to relatively recent adoption of BSS there is very little research exploring how people consider these systems within the existing transportation alternatives. Given the recent growth of BSS across the world, there is substantial ...

Many peer-to-peer overlay operations are inherently parallel and this parallelism can be exploited by using multi-destination multicast routing, resulting in significant message reduction in the underlying network. We propose criteria for assessing when multicast routing can effectively be used, and compare multi-destination multicast and host group multicast using these criteria. We show that ...

The peer-to-peer multimedia applications have recently generated much interest in wireless network infrastructure with supporting the quality-of-service (QoS) communications. In this paper, we propose a new on-demand QoS routing, namely link-state multi-path QoS routing, protocol in a wireless mobile ad-hoc network (MANET). Our proposed scheme offers a bandwidth routing protocol for QoS support...

In this paper we maximize the utility of a structural model of the demand for multi-destination non-work travel using maximum entropy method introduced by Shanon. A utility value is assigned when only partial information is available about the decision maker’s preferences. The maximum entropy utility solution embeds a large family of utility functions that includes the most commonly used functi...

Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time coding was used to maximize diversity gain. Assuming a low-rate feedback link from the destination to each relay stage and the source, this paper proposes end-to-end antenna selection strategies as an alternative to ...
