Optimal mainstream traffic flow control of large-scale motorway networks

The continuously increasing daily traffic congestions on motorway networks around the world call for innovative control measures that would drastically improve the current traffic conditions. Mainstream traffic flow control (MTFC) is proposed as a novel an ...

Optimal Motorway Traffic Flow Control Involving Variable Speed Limits and Ramp Metering

The impact of variable speed limits (VSL) on aggregate traffic flow behaviour on motorways is shown to bear similarities to the impact of ramp metering, in particular, when addressing potentially active bottlenecks. A quantitative model of the VSL impact i ...

Random Forest Models for Identifying Motorway Rear-End Crash Risks Using Disaggregate Traffic Data and Meteorological Information

André-Gilles Dumont, Edward Chung, Ashish Bhaskar, Minh Hai Pham

This paper presents an approach to develop motorway Rear-End Crash Risk Identification Models (RECRIM) using disaggregate traffic data, meteorological data and crash database for a study site at a two-lane-per-direction section on Swiss right-hand driving ...

A Cost-Effective Method for the Detection of Queue Lengths at Traffic Lights

Currently, the comparatively young floating car technology is mostly used to get information about travel times which however are more attractive to navigation and route guidance. Concerning traffic management applications such as traffic light control, it ...

Methodology for traffic risks identification

André-Gilles Dumont, Edward Chung, Minh Hai Pham

Of all modes of transport, transport by road is the most dangerous and the most costly in terms of human lives, according to Road Safety Action Program (2003-2010). In Europe, the 2010 road safety target of halving the number of road fatalities by 2010 see ...

Risk indicators - Unsafe traffic conditions

Edward Chung, Minh Hai Pham

This study proposes a framework for developing a pro-active system aiming at reducing motorway crash risk based on risk indicators. Although motorways are of safe road type by design, a crash if happens would be really severe. Reducing motorway crash risk ...

Effects of Variable Speed Limits on Motorway Traffic Flow

Variable speed limits (VSLs) displayed on roadside variable message signs (VMSs) have emerged as a widespread traffic control measure on motorways in many countries, leading to substantial traffic safety benefits; however, there is no clear evidence of imp ...

Multi-objective signal control of urban junctions - Framework and a London case study

This paper presents an approach to multi-objective signal control using fuzzy logic. The signal control uses fuzzy logic where the membership functions are optimised according to the Bellman-Zadeh principle of fuzzy decision-making. This approach is both p ...

Relating time-occupancy measurements to space-occupancy and link vehicle-count

The relationships between instantaneous space-variables and (easily measurable) local time-variables in largely homogeneous and stationary traffic flow, as typically encountered in uninterrupted traffic conditions, are briefly reviewed. An elaborate analys ...

SEVECOM - Secure Vehicle Communication

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya, Levente Buttyan

Vehicle to Vehicle communication (V2V) and Vehicle to Infrastructure communication (V2I) promise to improve road safety and optimize road traffic through cooperative systems applications. A prerequisite for the successful deployment of vehicular communicat ...
