Urban Dynamic Origin-Destination Matrices Estimation

André-Gilles Dumont, Edward Chung, Emmanuel Bert

The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) for dense urban networks. From reviewing existing methods, from static to dynamic OD matrix evaluation, possible deficiencies in the approa ...

Trajectory sampling with unreliable reporting

Matthias Grossglauser

We define and evaluate methods to perform robust network monitoring using trajectory sampling in the presence of report loss. The first challenge is to reconstruct an unambiguous set of packet trajectories from the reports on sampled packets received at a ...

Overview of Traffic Signal Operation Policies for Ramp Metering

A ramp metering control algorithm includes typically two distinct components: the (most important) control strategy, which makes real-time decisions on the ramp exit flow to be implemented, and the translation of this decision into specific traffic light s ...

Approach for Dynamic Origin-Destination Matrices Estimation in Urban Context

André-Gilles Dumont, Edward Chung, Emmanuel Bert

The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) in dense urban networks. From reviewing actual methods, for static and dynamic OD matrix evaluation, possible deficiencies in the approach ...

A cost-effective Method for the Detection of Queue Lengths at Traffic Lights

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 is more li ...

The workplace of Traffic Management Center Operators – what changes do experts foresee until 2020?

This paper aims to understand the dynamics of the Traffic Management Center operator workplace. Currently we can observe an expansion of tools, tasks and traffic volumes the operator has to handle. Using expert interviews and Mayring’s Qualitative Content ...

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 ...

Applicability of road safety indicators to assess driving risks under Swiss road conditions

André-Gilles Dumont, Edward Chung, Minh Hai Pham

Road traffic crash is a problem in every country. According to World Health Organization, in Europe there are about 127,000 people killed and at least some 2.4 million injured each year. Incident detection algorithms to detect incidents on motorways are we ...

Mobile mapping en temps réel pour la saisie automatique d'axes routiers

Hervé Gontran

The development of road telematics requires the management of ever-growing databases related to traffic fluidity, live consignment monitoring and vehicle fleet tracking, as to driver assistance. Such an effort relies on the tight synergy between navigation ...

Using global positioning system for bus priority in London: traffic signals close to bus stops

London's bus network is one of the largest and most comprehensive urban transport systems in the world. The contribution of buses is recognised by implementing a series of initiatives including bus priority at traffic signals. London has a long history of ...
