Hoogendoorn, S.P. (author), Bovy, P.H.L. (author), Van der Zijpp, N.J. (author)In the course of the Telematics implications Programme Transport of the European Commission Fourth Framework Research Programme much attention is devoted to evaluation and demonstration. This report is part of the DACCORD project TR1017, devoted to the development and application of co-ordinated traffic control in freeway corridors. The report...report 1997

Hoogendoorn, S.P. (author), Bovy, P.H.L. (author)In this report we derive a macroscopic Multiple User-Class traffic model from mesoscopic principles. These principles yield equilibrium relationships between traffic density and equilibrium velocities as a function of the current traffic conditions, the traffic composition, and the distribution of user-class dependent desired velocities, rather...report 1998

Hoogendoorn, S.P. (author), Bovy, P.H.L. (author)This report represents the second report in regarding macroscopic traffic flow modelling. In this report we present a multiple lane generalisation of the aggregate-lane multiple user-class model. Key to its derivation is the lane-specific multiple user-class phase-space density (MUCPSD), generalising the traditional spatial density by...report 1998

Hoogendoorn, S.P. (author)This report presents results of research carried out in the ADVISORS project. The objective of this research is to develop a methodology to assess road traffic efficiency and environmental impacts of Advanced Driver Assistanc e Systems (ADAS) at both the microscopie and the network level. The results discussed in this report pertain to the...report 2001

Hoogendoorn, S.P. (author)Gaining insights into pedestrian flow operations and assessment tools for pedestrian walking speeds and comfort is important in for instance planning and geometric design of infrastructural facilities. Additionally, management of pedestrian flows requires knowledge of pedestrian flow behavior. However, compared to vehicular traffic, pedestrian...report 2001

Hoogendoorn, R.M. (author)Studies in stratigraphy are often driven by the predicted climate change and possible gains for the oil and gas industry. Because, at present predictions of the development of future deltaic architecture are insufficient. This thesis addresses the problem of qualitative and quantitative understanding of sedimentary systems in two stages. In the...doctoral thesis 2006

Knoop, V. (author), Van Zuylen, H. (author), Hoogendoorn, S. (author)Robustness of a network is a main objective for road network managers these days, and has therefore become an important study area for transportation scientists. This article discusses one specific aspect in assessing road network robustness: the consequences of the closure of a link. These spillback effects have been examined in a dedicated...journal article 2008

Knoop, V.L. (author), Hoogendoorn, S.P. (author), Van Zuylen, H.J. (author)The delay caused by an incident depends on many variables. This paper introduces an analytical expression for the delay, describing the location and length of the queue by shockwave theory. As long as the congestion remains on the same link, delay is proportional to the square of the duration, even in case the outflow is reduced by a junction...conference paper 2009

Knoop, V.L. (author), Van Zuylen, H.J. (author), Hoogendoorn, S.P. (author)Much of the delays on road networks are caused by incidents. This is partially caused by blockage or closure of lanes, but also by the change of driving behaviour in the remaining lanes. This contribution analyses traffic flow conditions near an incident both microscopically and macroscopically. A theory is proposed to describe drivers’...conference paper 2009

Zo ja, hoe dan? Zijn er bruikbare modellen om effecten in te schatten? En hoe staat het met de human factor, welhaast in elke keten de meest kwetsbare schakel...journal article 2009

Knoop, V. (author), Hoogendoorn, S. (author), Adams, K. (author)Incidents cause a large part of the delays in road networks. This is caused by a decrease of the capacity at the incident site. A detailed knowledge of the queue discharge rate can improve for instance the traffic prediction and thereby improve delay information or routing advice. Therefore, this study determines the queue discharge rate for...journal article 2009

Knoop, V.L. (author), Hoogendoorn, S.P. (author), Van Zuylen, H.J. (author)The duration of incidents is a stochastic variable with a variation spread. This chapter analyzes the consequences of this stochastic nature of the duration in terms of delay. It uses shockwave theory to describe traffic states. As opposed to a point queue model, the head and the tail of the queue are separately modeled and in this way the...conference paper 2010

Knoop, V.L. (author), Snelder, M. (author), Van Zuylen, H.J. (author), Hoogendoorn, S.P. (author)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...conference paper 2010
