Abstract Several European road operators and authorities joined the C-Roads Platform with aim of harmonising deployment activities cooperative intelligent transport systems (C-ITS). C-ITS research is preliminary to future automated-driving vehicles. The current conventional highways were designed on traditional criteria models specifically developed for traffic flows manually guided Thus, this ...

Frontage roads are most frequently used in rural and urban environments along freeway and full-controlled principal arterial corridors. Their primary function is to distribute and collect traffic between local streets and interchanges. They have been the primary design solution for providing access along Texas rural freeways and full-controlled principal arterials. With the growing public deman...

Because of the aging infrastructure, methods are explored by which reliability existing bridges and viaducts can be assessed. In cases in limited information structure is available or its condition concern, proof load testing may used to demonstrate sufficient live carrying capacity. Proof tests U.S.A. typically performed using Manual for Bridge Evaluation (MBE) published American Association S...

Results of research on roundabouts in the United States are presented in the NCHRP Report 572. The findings and recommendations of this report are important as they will be the basis of the 2010 Highway Capacity Manual methodology for operational analysis of roundabouts. This paper discusses various findings and recommendations of the NCHRP Report 572 on roundabout capacity and level of service...

Computerized systems are becoming smaller, ubiquitous and more interconnected. Netbooks to smart highways all are expected to be more autonomous and connected to each-other. Such interconnected systems have to manage information and regulate actions on their own, with minimal external guidance. A sensor network is a typical example. With scarce resources and no ready infrastructure, it forms a ...

It is sometimes the case that some economic goods are perfect complements to some agents, but not to all agents. As an illustration, consider the following highly stylized story. A regulator faces the problem of pricing the use of a given network, e.g., a highway network. For our purposes, a network is simply a graph, with no loop. Each edge of the graph has a capacity: the maximal amount of tr...

In this paper we analyze in detail the energy consumption characteristics of the Wireless HART protocol when operated with a popular transceiver, the ChipCon CC2420. We analyze how much various factors contribute to the overall energy consumption over a longer period of 12 h. These factors include the amount of management traffic and the power levels required for various transceiver activities ...

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...
