Impacts of the Coordination of DTMs with Different Local Control Objectives Considering Their Spatial Layout

With the steadily increasing road traffic demand, congestion on freeways has become a major problem. With the development of communication technology and automated vehicles, there are more opportunities for DTMs to be studied extensively at the coordination level and cooperation level. In the existing literature, the coordination of RM (ramp...

COBRA: A cooperative breakdown prevention algorithm

Ever increasing traffic load on freeways calls for smart solutions to improve throughput. With the uprise and standardization of C-ITS, accuracy and latency of traffic state measurements are immensely improved, while the span of control is increased. In this paper, a traffic control algorithm that aims to prevent breakdown at recurring...

Analysis of current Dutch traffic management effectiveness with automated vehicles: a ramp-metering case study: Simulation Study

Automated vehicles are conventional vehicles equipped with advanced sensors, controller and actuators. They achieve intelligent information exchange with the environment through the onboard sensing and cooperative system. vehicles are possible to have situation awareness and automatically analyze the safety and dangerous state of journeys....

Road-user participation in vehicle-data sharing systems: for the purpose of dynamic traffic management

This study aims to provide insight into how factors relating to privacy and incentives influence people's willingness to participate in sharing their vehicle based sensing data with governmental parties for the purposes of improved dynamic traffic management in the Netherlands. Through the use of a stated preference experiment data is gathered...

Short-term traffic prediction in road traffic control centres: Efficient traffic state estimation based on a localized deterministic Ensemble Kalman Filter

Traffic state estimations and predictions are essential parts for dynamic traffic management applications. This thesis consists of two parts: firstly the requirements for application of a traffic prediction tool in a road traffic management center are analysed, and a design is made for a tool to function in non-recurrent conditions and cope with...

Route Guidance and Signal Control Based on the Back-Pressure Algorithm

Bad traffic conditions can be improved by regulating traffic demand and network capacity. Dynamic Traffic Management (DTM) systems allocate temporal and spatial utilization of infrastructures and vehicle fleets by means of dynamic signals. By timely response to changing traffic conditions DTM goals, in terms of effective, safe and reliable use...

Dynamic OD demand estimation and prediction for dynamic traffic management

Dynamic origin-destination (OD) demand is important input to many simulation models applied within dynamic traffic management systems (DTMS) for predicting traffic states on the network. The inability to provide high-quality dynamic OD demand estimates makes prediction with simulation models simply impossible, irrespective of how well these...

Schiphol's dynamic traffic Management: A case study on rescheduling

Around the railway station of Schiphol, railway traffic is controlled by an automated dynamic traffic management system (DVM). This system is not optimal for the future service pattern of NS and NS Hispeed. My research explores the possibilities of a new DVM by analysing different rescheduling elements by means of microsimulations in OpenTrack.

Lagrangian Multi-Class Traffic State Estimation

Road traffic is important to everybody in the world. People travel and commute everyday. For those who travel by cars (or other types of road vehicles), traffic congestion is a daily experience. One essential goal of traffic researchers is to reduce traffic congestion and to improve the whole traffic system operation and the environment. To...

Vehicle-class Specific Control of Freeway Traffic

The increase of mobility of the past decades has led to substantial congestion on the freeways. Traffic jams emerge both on a daily basis at the same location, as well as during accidents when a part of the freeways is temporarily blocked. In those cases, traffic management centers intervene into traffic in order to reduce or even dissolve...

Application of Macroscopic Fundamental Diagrams to Dynamic Traffic Management

This thesis project is a part of Dutch project PraktijkProef Amsterdam (PPA), in which the coordinated network traffic management in the regional area is analyzed. One of control levels in the project PPA is sub-networks, where the concept of the macroscopic fundamental diagram (MFD) is applied. Unlike a conventional link fundamental diagram, an...
