Hoogendoorn, S.P. (author), Knoop, V.L. (author)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...journal article 2013

Knoop, V.L. (author), Hoogendoorn, S.P. (author)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...conference paper 2013

Goni Ros, B. (author), Knoop, V.L. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)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...conference paper 2013

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)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...conference paper 2013

Rhasbudin Shah, S.M. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)Incidents can affect the flow in non?incident direction due to rubbernecking. To this date, only homogeneous rubbernecking behaviour has been assessed. This study provides insights into inter?driver heterogeneity in rubbernecking behaviour while passing an incident site. We use empirical trajectory data obtained from a helicopter?mounted video...conference paper 2013

Knoop, V.L. (author), Hoogendoorn, S.P. (author)On a motorway, drivers make decisions on their speed. It has been shown that drivers change their acceleration only at specific times and not continuously. Lane changes are also made at discrete moments in time. This paper determines the moments when drivers change their acceleration and moments when they change lanes. Fitting longitudinal and...conference paper 2013

Knoop, V.L. (author), Hoogendoorn, S.P. (author)Due to increasing exchange of data between measurement sites, the area over which traffic control is applied increases. This leads to three new challenges: (1) working with the large quantities of data (transmit, store), (2) estimating the traffic state, (3) controlling a large area with many controllers (and hence large solution space). This...conference paper 2013

Knoop, V.L. (author), Hoogendoorn, S.P. (author), Van Lint, J.W.C. (author)Literature shows that – under specific conditions – the macroscopic fundamental diagram (MFD) describes a crisp relationship between the average flow (production) and the average density in an entire network. The limiting condition is that traffic conditions must be homogeneous over the whole network. Recent works describe hysteresis effects:...conference paper 2013

Hoogendoorn, S.P. (author), Knoop, V.L. (author)When do traffi c jams emerge? Can we predict, given certain demand levels, when queuing will occur, how long the queues will be, how they will propagate in space and time and how long it will take for the congestion to resolve? Why does an overloaded traffic network underperform? This chapter gives a basic introduction to traffic flow theory...book chapter 2012

Knoop, V.L. (author), Hoogendoorn, S.P. (author), Van Lint, J.W.C. (author)An excess number of vehicles in a traffic network will reduce traffic performance. This reduction can be avoided by traffic management. In particular, traffic can be routed such that the bottlenecks are not oversaturated. The macroscopic fundamental diagram provides the relation between the number of vehicles and the network performance. One can...conference paper 2012
