An Iterative Adaptive Dynamic Programming Approach for Macroscopic Fundamental Diagram-Based Perimeter Control and Route Guidance

Macroscopic fundamental diagrams (MFDs) have been widely adopted to model the traffic flow of large-scale urban networks. Coupling perimeter control and regional route guidance (PCRG) is a promising strategy to decrease congestion heterogeneity and reduce ...

Modelling transport time to trauma centres and 30-day mortality in road accidents in Switzerland: an exploratory study

Stéphane Joost

BACKGROUND: Rapid access to a trauma centre for severely injured road accident victims, conceptualised as the Golden Hour, links access time to definitive treatment within 1 hour of trauma with reduced risks of morbidity and mortality. Access times have no ...

Study of Donor-like Surface Trap Emission in GaN HEMTs

Farzan Jazaeri

Gate-lag induced trapping effects due to donor-like surface traps located in the access regions between the electrodes of AlGaN/GaN HEMTs are investigated through TCAD transient simulations. The effects of variation in trap energy level and temperature on ...

Overpass bridge of the L3378 road near Fulda-Lehnerz First application of UHPFRC in road bridge construction in Germany. Part 1

Eugen Brühwiler

Aging bridges of the German federal road network often cannot be rehabilitated or replaced timely due to insufficient funding and complex regulations of building laws. Consequently, novel building materials and alternative solutions get the opportunity to ...

The scaling structure of the global road network

Andrea Rinaldo, Enrico Bertuzzo, Emanuele Strano, Andrea Giometto

Because of increasing global urbanization and its immediate consequences, including changes in patterns of food demand, circulation and land use, the next century will witness a major increase in the extent of paved roads built worldwide. To model the effe ...

VNToR: Network Virtualization at the Top-of-Rack Switch

Edouard Bugnion, Aikaterini Argyraki, Georgios Ioannidis, Sam David Whitlock, Jonas Fietz

Cloud providers typically implement abstractions for net- work virtualization on the server, within the operating sys- tem that hosts the tenant virtual machines or containers. Despite being flexible and convenient, this approach has funda- mental problems ...

Cruising-for-parking in congested cities with an MFD representation

Nikolaos Geroliminis

It has been recently proposed and tested that traffic in large urban regions (neighbourhoods) can be modelled dynamically at an aggregate level, if the neighbourhoods are uniformly congested. By exploiting the insights and the properties of a macroscopic f ...

On the distribution of urban road space for multimodal congested networks

Nikolaos Geroliminis, Nan Zheng

Transport systems in real cities are complex with many modes of transport sharing and competing for limited road space. This work intends to understand how space distributions for modes and interactions among modes affect network traffic performance. While ...

Investigation of Lane Flow Distribution on Hard Shoulder Running Freeways

André-Gilles Dumont, Dimitrios Efthymiou, Sofia Samoili

Responding to an impending demand growth at an existing reactive managed lane system, and in order to provide a timely and more effective temporary hard shoulder activation, short-term prediction models are developed. A lane-oriented attribute, namely the ...

An Empirical Analysis on the Arterial Fundamental Diagram

Nikolaos Geroliminis

For uninterrupted traffic flow, it is well-known that the fundamental diagram (FD) describes the relationship between traffic flow and density under steady state. For interrupted traffic flow on a signalized road, it has been recognized that the arterial f ...
