Yuan, Y. (author), Pel, A.J. (author), Hoogendoorn, S.P. (author)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...conference paper 2014

Han, Y. (author), Yuan, Y. (author), Hoogendoorn, S.P. (author)We propose an integrated approach for dynamic route guidance and ramp metering using Linear Quadratic Model Predictive Control (LQMPC). The main objective is to maximize the throughput of the network by guiding traffic flow towards to insufficiently utilized infrastructures. Due to the linear property of the LQMPC, it is fast enough for real...conference paper 2014

Van de Weg, G.S. (author), Hegyi, A. (author), Hoogendoorn, S.P. (author)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....conference paper 2014

Calvert, S.C. (author), Taale, H. (author), Hoogendoorn, S.P. (author)In this contribution the Core Probability Framework (CPF) is introduced with the application of the Discrete-Element Core Probability Model (DE-CPM) as a new DNL for dynamic macroscopic modelling of stochastic traffic flow. The model is demonstrated for validation in a test case and for computational efficiency on two simple networks. The CPF...conference paper 2014

Van Wageningen-Kessels, F.L.M. (author), Van Lint, J.W.C. (author), Hoogendoorn, S.P. (author), Vuik, C. (author)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...journal article 2014

Goni Ros, B. (author), Knoop, V.L. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)We present a new control strategy that aims to reduce total delay at sags. The strategy is based on the concept of mainstream traffic flow control. The traffic density at the bottleneck area is regulated in order to keep it slightly below the critical density, hence preventing traffic from breaking down while maximizing outflow. Density is...conference paper 2014

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)The Macroscopic or Network Fundamental Diagram (NFD) describes the relationship between the network flow and the number of travellers within the network. The shape of the NFD is important for control purposes like perimeter control or routing. However, it is unknown how the network structure influences the shape of the NFD. This is studied in...conference paper 2014

Djukic, T. (author), Van Lint, J.W.C. (author), Hoogendoorn, S.P. (author)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...conference paper 2014

Knoop, V.L. (author), Hoogendoorn, S.P. (author)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...conference paper 2014

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)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...conference paper 2014

Goni Ros, B. (author), Knoop, V.L. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)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...conference paper 2014

Van Wageningen-Kessels, F.L.M. (author), Hoogendoorn, S.P. (author), Vuik, C. (author), Van Lint, J.W.C. (author)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...lecture notes 2014

Klunder, G. (author), Hoogendoorn, S.P. (author), Kester, L. (author), Taale, H. (author)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...journal article 2013
