Optimal lane guidance for improving traffic efficiency on homogeneous freeway sections

Urban network throughput optimization via model predictive control using the link transmission model

Developing practicable and efficient real-time signal control strategies for urban road networks is a major challenge with significant scientific and practical relevance. For the sake of practical feasibility, many urban traffic control strategies are based on simplified models. In this way, a trade-off can be made between controller accuracy,...

Robust, Optimal, Predictive, and Integrated Road Traffic Control: Research proposal

The development of control strategies for traffic lights, ramp metering installations, and variable speed limits to improve the throughput of road traffic networks can contribute to a more efficient use of road networks. In this project, a hierarchical controller will be developed for the improvement of the throughput of a road traffic network....

Improving the road network performance with dynamic route guidance by considering the indifference band of road users

When applying dynamic route guidance to improve the network performance, it is important to balance the interests of the road authorities and the road users. In this paper we will illustrate how bounded rationality and indifference bands can be taken into account in dynamic route guidance to improve the network performance while respecting the...

Network Wide Service Level-Oriented Route Guidance in Road Traffic Networks: Traffic management in line with the policy objectives of the road authorities

Service level control is a promising strategy to realize policy objectives within road networks like improving network production while taking road user interests, livability and safety into account. In this contribution a service level-oriented route guidance control approach is presented that is able to control service levels of routes on a...

Service level-oriented route guidance during evacuations

Research in the field of evacuation management puts a strong focus on the development of optimal evacuation and control strategies. However, in operational evacuation management the means to monitor, manage, evaluate and control are limited. The authorities nevertheless have a strong need to understand the system, in order to properly guide...

Vehicle-class Specific Route-guidance of Freeway Traffic by Model-predictive Control

Few Active Traffic Management measures proposed in the past consider the distinction of different vehicle classes. Examples of vehicle-class specific measures are truck lanes and high-occupancy/toll (HOT) lanes. We propose that the distinction of different vehicle classes, with different flow characteristics and societal and economic function,...

Efficient particle-based estimation of marginal costs in a first-order macroscopic traffic flow model

Marginal costs in traffic networks are the extra costs incurred to the system as the result of extra traffic. Marginal costs are required frequently e.g. when considering system optimal traffic assignment or tolling problems. When explicitly considering spillback in a traffic flow model, one can use a numerical derivative or resort to heuristics...

Online travel time estimation in urban areas using the occupancy of long loop detectors

Roads in the Netherlands are often heavily congested. Real-time travel time information can be a valuable instrument to reduce the impact of increasing traffic demand on travel time with advantages for traffic participants as well as for the traffic network managers. For urban roads travel time estimation is a more complex problem than for...
