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...

The Macroscopic or Network Fundamental Diagram (NFD) describes the network performance as a function of the number of vehicles. Even if the network has the same roadway length, type of roads, number of intersections and traffic light setting strategy, the shape of the NFD changes. Therefore, the NFD needs to be calculated or simulated separately...

In the past decade an increase in research regarding stochasticity and probability in traffic modelling has occurred. The realisation has grown that simple presumptions and basic stochastic elements are insufficient to give accurate modelling results in many cases. This paper puts forward a strong argument for the further development and...

Tehran is capital of Iran in wide metropolitan area. Large-scale disasters such as earthquakes in such a city cause many casualties and economical damage. One of the most effective risk mitigation actions in such disasters is emergency evacuation. This paper evaluates the dynamics of the vehicular traffic of Tehran under an evacuation condition....

Automated driving potentially has a significant impact on traffic flow efficiency. Automated vehicles, which possess cooperative capabilities, are expected to reduce congestion levels for instance by increasing road capacity, by anticipating traffic conditions further downstream and also by accelerating the clearance of congestion. However, the...

Since lane changes influence traffic operations, it is useful to know their frequency for various conditions. This paper studies the number of lane changes as function of the roadway characteristics. Two sites are studied, for which individual lane change data is available. The paper shows that the most constant measure is the lane change rate,...

Earlier studies have shown how driving behaviour during emergency evacuation is different from that under “normal” conditions. At the same time, most evacuation studies (where the driving performance is explicitly accounted for) were conducted under the assumption of a fully activated emergency environment. However, the transition phase in...

Literature proposes link-based indicators as predictors of the delay caused by a blockade on a particular link. This paper cross-compares these indicators and compares them with the result of a full simulation. The indicators predict different links to be vulnerable. Furthermore, the indicators do not provide a good indication of the delay of a...

Lane changes are an important aspect of freeway flow. Most lane change models are microscopic, describing whether individual vehicles/drives will change lanes, and hence are calibrated microscopically. Macroscopic validation often is restricted to the distribution of vehicles across lanes. To the best of our knowledge, no systematic analysis has...

Bereikbaarheid en daarmee mobiliteit en transport systemen zijn van vitaal belang van onze steden en regio’s. Verkeer en vervoer spelen een cruciale rol in het mogelijk maken van activiteiten voor mensen en bedrijven. Maatregelen, ingrepen en innovaties laten historisch een verbetering van de bereikbaarheid zien en daarmee van de vrijheid van...

New IT techniques allow communication and coordination between traffic measures. To best use this, one needs to coordinate over longer distances. Optimization of the measures is not possible using traditional microscopic or macroscopic simulation models. The Network Fundamental Diagram (NFD) describes the relation between flow and density on a...

Automated vehicles are expected to have a substantial impact on traffic flow efficiency, safety levels and levels of emissions. However, Fields Operational Tests suggest that drivers may prefer to disengage Adaptive Cruise Control (ACC) and resume manual control in dense traffic conditions and before performing manoeuvres such as lane changing....

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...

Capacity drop indicates that the queue discharge rate is lower than the road capacity. Due to the capacity drop, traffic delays increase once queues form. Researchers find that queue discharge rates vary in different traffic conditions. Empirical data shows that the queue discharge rate increases as the speed in congestion increases....

The vision of intelligent vehicles traveling in road networks has prompted numerous concepts to control future traffic flow, one of which is the in-vehicle actuation of traffic control signals. The key of this concept is using intelligent vehicles as actuators for traffic control systems, replacing the traditional road-side systems. Under this...

We propose and analyze a generic multi-class kinematic wave traffic flow model: Fastlane. The model takes into account heterogeneity among driver-vehicle units with respect to speed and space occupancy: long vehicles with large headways (e.g. trucks) take more space than short vehicles with short headways (e.g. passenger cars). Moreover, and...
