In previous work, we have explored the idea of dimensionality reduction and approximation of OD demand based on principal component analysis (PCA). In particular, we have shown how we can apply PCA to linearly transform the high dimensional OD matrices into the lower dimensional space without significant loss of accuracy. Next, we have defined a...

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...

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...

It is analyzed what the effect is of the exact network structure on the shape of the Network Fundamental Diagram (NFD). In order to do so, a tool is developed which can create random networks for which the aggregated properties are the same. Using this tool, different urban networks with the same properties are designed. They show different NFDs...

Sags are freeway sections along which the gradient changes significantly from downwards to upwards. The capacity of sags is significantly lower than the capacity of normal sections. As a result, sags often become bottlenecks in freeway networks, causing the formation of congestion in conditions of high traffic demand. Congestion results in a...

80 years ago, Bruce Greenshields presented the first traffic flow model at the Annual Meeting of the Highway Research Board. Since then, many models and simulation tools have been developed. We show a model tree with four families of traffic flow models, all descending from Greenshields' model. The tree shows the historical development of...

Heb je het met iemand over verkeersdata, dan valt – naast de zo populaire kreet ‘big data’ – bijna altijd de term datafusie. In veel gevallen is het echter helemaal niet zo duidelijk wat daar nu precies mee wordt bedoeld en waarom het zinvol zou zijn. In deze tutorial daarom een korte introductie. We gaan daarbij vooral in op de kwaliteit van...

In deze tutorial bespreken we de nieuwste inzichten op het gebied van netwerkdynamica. En nu eens niet op de traditionele manier, waarbij we proberen om een verkeersnetwerk in al haar detail zo nauwkeurig mogelijk te analyseren, modelleren en simuleren. Nee, in deze bijdrage zullen we juist vanuit vogelperspectief naar de verkeersafwikkeling in...

There is a growing interest in the traffic community about the relation between traffic data quality and the efficiency of traffic management. Data collection is expensive and if the same level of traffic performance can be reached with less data or if traffic management becomes more efficient with better data, then that is interesting for a lot...

This paper deals with the optimal allocation of routes, destination, and departure times to members of a crowd, for instance in case of an evacuation or another hazardous situation in which the people need to leave the area as quickly as possible. The generic approach minimizes the evacuation times, considering the demand dependent waiting times...

Verkeersmodellen worden gebruikt om de verkeerssituatie te voorspellen. Daarbij zijn twee dimensies van belang: het detailniveau van het model en de beschikbare rekentijd. Dit artikel analyseert de beide dimensies en de argumenten aan om voor een bepaald niveau te kiezen. Het artikel geeft voorbeelden van beschikbare modellen, maar gaat bovenal...

Maritime traffic safety and capacity raise enormous attention nowadays, especially in ports and inland waterways with high traffic density and restricted waterway geometry. However, a limited number of factors is considered in existing maritime models. Especially influences of external factors (wind, visibility and current), vessel encounters...

Sags are freeway sections along which gradient changes significantly from downwards to upwards. Sags are often bottlenecks in freeway networks. Capacity decreases due to changes in car-following behavior. We present a microscopic traffic flow model that describes driving behavior and traffic flow dynamics at sags. The model includes a new...
