ITETRIS: a modular simulation platform for the large scale evaluation of cooperative ITS applications

Cooperative ITS systems are expected to improve road traffic safety and efficiency, and provide infotainment services on the move, through the dynamic exchange of messages between vehicles, and between vehicles and infrastructure nodes. The complexity of c ...

City size, network structure and traffic congestion

Nikolaos Geroliminis

This paper presents an alternative approach for analyzing the relationship between land use and traffic congestion by employing the Macroscopic Fundamental Diagram (MFD). The MFD is an empirically observed relationship between traffic flow and traffic dens ...

Experienced travel time prediction for congested freeways

Nikolaos Geroliminis, Mehmet Yildirimoglu

Travel time is an important performance measure for transportation systems, and dissemination of travel time information can help travelers make reliable travel decisions such as route choice or departure time. Since the traffic data collected in real time ...

Two-phase flow operational maps for multi-microchannel evaporators

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

The current paper presents new operational maps for several different multi-microchannel evaporators, with and without any inlet restrictions (micro-orifices), for the two-phase flow of refrigerants R245fa, R236fa, and R1234ze(E). The test fluids flowed in ...

Relationship between application scale and maximum time latency in Intelligent Transport Systems

Congestion is a major problem in large, urbanized areas. Intelligent transport solutions aim to reduce this problem. In general, traffic is monitored with the use of sensors, the resulting data are processed, a traffic state is estimated, and a control mea ...

Joint Source and Transmission Rate Modeling in Adaptive Video Streaming

Pascal Frossard, Lorenzo Rossi

This work addresses the modeling of traffic generated by a video source operating in the context of adaptive streaming services. Traffic modeling is a key in several network design issues, such as dimensioning of core and access network resources, developi ...

Designing Best Effort Networks-on-Chip to Meet Hard Latency Constraints

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Ciprian Seiculescu, Hamid Sarbazi-Azad, Dara Rahmati

Many classes of applications require Quality of Service (QoS) guarantees from the system interconnect. In Networks-on-Chip (NoC) QoS guarantees usually translate into bandwidth and latency constraints for the traffic flows and require hardware support in t ...

Bimodal sound source tracking applied to road traffic monitoring

Patrick Marmaroli

The constant increase of road traffic requires closer and closer road network monitoring. The awareness of traffic characteristics in real time as well as its historical trends, facilitates decision-making for flow regulation, triggering relief operations, ...

An aggregate model for transient and multi-directional pedestrian flows in public walking areas

Michel Bierlaire, Bilal Farooq, Flurin Silvan Hänseler

A dynamic pedestrian propagation model applicable to congested and multi-directional flows is proposed. Based on the cell transmission model, several important extensions are made to describe the simultaneous and potentially conflicting propagation of mult ...

Unified mechanistic multiscale mapping of two-phase flow patterns in microchannels

John Richard Thome, Rémi Revellin, Iztok Zun

To better understand the underlying two-phase phenomena and thus better predict transitions between the various two-phase flow patterns, it is necessary to update our way of thinking from one-of-a-kind flow pattern maps of limited applicability to a genera ...
