The next smart move: A decision support system for urban implementation of smart mobility solutions

The urban mobility sector is developing at a fast pace and is demanding transportation systems to be resilient and sustainable. Policy makers deal with an extensive offer of new technologies but lack an overview of the contribution of these mobility solutions to their urban planning ambitions. Uncertainty exists regarding both the technological...

Ramp Metering with Real-Time Estimation of Parameters

Demand exceeding the capacity of a bottleneck will create congestion upstream of that bottleneck. Once this congestion occurs, the maximum flow through this bottleneck decreases (capacity drop). By limiting the flow towards the bottleneck, one can prevent or postpone the capacity drop and the accompanying congestion. In case the bottleneck is...

Information engineering for supporting situation awareness of nautical traffic management operators

The main challenge of operators working with complex information systems is to gain sufficient situation awareness (SA). In this research project, we developed an analysis scheme to support a holistic study of SA. This analysis scheme was complemented with a method to process cognitive task analysis and observational research data to identify...

Online Anticipatory Network Management: The dynamic steering of route choice behaviour with traffic control and traffic information

In order to improve the usage efficiency of the road network, this research investigates and proposes an approach for a traffic management solution called Online Anticipatory Network Management. The proposed traffic management solution aims to redistribute traffic flows and to increase network performance by determining and applying traffic...

Real Time Traffic Models, Decision Support for Traffic Management

Reliable and accurate short-term traffic state prediction can improve the performance of real-time traffic management systems significantly. Using this short-time prediction based on current measurements delivered by advanced surveillance systems will support decision-making processes on various control strategies and enhance the performance of...

The effect of inaccurate traffic data for ramp metering: Comparing loop detectors and cameras using information utility

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

A systematic approach to adressing the influence of man-machine interaction on situation awareness

This paper presents a systematic approach towards the study of required situation awareness (RSA) in traffic management context. Current theories are not suitable to clearly define the RSA in complex man-machine interaction (MMI) contexts. Deficiencies of man-machine interaction are difficult to recognize and resolve. This paper analyzes: (i)...

Real time traffic models, decision support for traffic management

Reliable and accurate short-term traffic state prediction can improve the performance of real-time traffic management systems significantly. Using this short-time prediction based on current measurements delivered by advanced surveillance systems will support decision-making processes on various control strategies and enhance the performance of...

Simulation of Traffic Capacity of Inland Waterway Network

The inland waterborne transportation is viewed as an economic, safe and environmentally friendly alternative to the congested road network. The traffic capacity are the critical indicator of the inland shipping performance. Actually, interacted under the complicated factors, it is challenging to conduct studies on the capacity in the networks of...

A quick-scan appraisal method to determine cost-effectiveness of Traffic and Demand Management measures

This paper presents this quick-scan approach for assessing the cost-effectiveness of smaller and not-well demarcated transport measures that can be used as a first-scan while establishing packages to deal with certain transport problems. It adds to the available evaluation literature (see section 2) in relying on a combination of expert opinions...

Fastlane: Traffic flow modeling and multi-class dynamic traffic management

Dynamic Traffic Management (DTM) aims to improve traffic conditions. DTM usually consists of two steps: first the current traffic is estimated, then appropriate control actions are determined based on that estimate. In order to estimate and control the traffic, a suitable traffic flow model that reproduces the properties of traffic well must be...

A Framework for the Modelling and Ex-ante Evaluation of Coordinated Network Management

Since the second half of last century, traffic congestion on road network has become a predominant phenomenon due to the rapid increases in transport demand and number of vehicles. It starts to become clear until later that century traffic congestion cannot be solved single-handedly by expansions of road network. During peak hours, besides...

A Comparison of Freeway Work Zone Capacity Prediction Models

To keep the freeway networks in a good condition, road works such as maintenance and reconstruction are carried out regularly. The resulting work zones including the related traffic management measures, give different traffic capacities of the infrastructures, which determines the travel time for road users. A work zone capacity prediction model...

Railway Network Timetabling and Dynamic Traffic Management

The paper discusses the current state of research concerning railway network timetabling and traffic management. Timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. Analytic (queuing) models and stochastic micro-simulation are...

Ex-post evaluation of network-wide Dynamic Traffic Management: Proposal for a theory-based evaluation methodology

Integrated anticipatory control of road networks: A game-theoretical approach

In The Netherlands, dynamic traffic management is an important approach to minimise the negative effects of increasing congestion. Measures such as ramp metering and route infor-mation, but also conventional traffic signal control, are used for this. Traditionally, the focus in designing traffic control plans has been on local control. There is...
