Pel, A.J. (author), Bliemer, M.C.J. (author), Hoogendoorn, S.P. (author)An essential feature in many dynamic traffic assignment (DTA) models used for planning purposes is to compute the (dynamic) equilibrium assignment, where travellers follow user-optimal routes, leading to minimal experienced route travel times. To compute these time-varying route flows in the equilibrium assignment, an iterative procedure is...conference paper 2010

Pel, A.J. (author), Huibregtse, O.L. (author), Hoogendoorn, S.P. (author), Bliemer, M.C.J. (author)Instructing evacuees on their departure time, destination, and route can lead to more efficient evacuation traffic operations. While current evacuation plan optimization techniques are limited to assessing mandatory evacuation where travelers strictly follow the instructions, in reality a share of travelers likely decides not to comply. Here we...conference paper 2010

Huibregtse, O.L. (author), Hoogendoorn, S.P. (author), Pel, A.J. (author), Bliemer, M.C.J. (author)A method is described to develop a set of optimal instructions to evacuate by car the population of a region threatened by a hazard. By giving these instructions to the evacuees, traffic conditions and therefore the evacuation efficiency can be optimized. The instructions, containing a departure time, a destination, and a route, are created...conference paper 2010

Van Hinsbergen, C.P.IJ. (author), Van Lint, H.W.C. (author), Hoogendoorn, S.P. (author), Van Zuylen, H.J. (author)Recent research has revealed that there exist large inter-driver differences in car-following behavior such that different car-following models may apply to different drivers. This study applies Bayesian techniques to the calibration of car-following models, where prior distributions on each model parameter are converted to posterior...conference paper 2010

Zuurbier, F.S. (author), Hegyi, A. (author), Hoogendoorn, S.P. (author)Marginal costs in traffic networks are the extra costs incurred to the system as the result of extra traffic. Marginal costs are required frequently e.g. when considering system optimal traffic assignment or tolling problems. When explicitly considering spillback in a traffic flow model, one can use a numerical derivative or resort to heuristics...conference paper 2010

Yuan, Y. (author), Daamen, W. (author), Hoogendoorn, S. (author), Vrancken, D. (author)The steadily increasing numbers and lengths of traffic jams on freeways have led to the application of Dynamic Traffic Management (DTM) measures all over the world. Ramp metering control has proven to be one of the most efficient means to reduce freeway congestion. Currently, it is expected that integrated and coordinated application of DTM...conference paper 2010

Mak, W.K. (author), Viti, F. (author), Hoogendoorn, S.P. (author), Hegyi, A. (author)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...conference paper 2010

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), 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 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

Knoop, V.L. (author), Snelder, M. (author), Van Zuylen, H.J. (author), Hoogendoorn, S.P. (author)It is computationally expensive to find out where vulnerable parts in a network are. In literature a variety of methods were introduced that use relatively simple selection criteria (measured in real-life or calculated in a traffic simulator) to pre-determine the seriousness of the delays caused by the blocking of that link and thereafter...conference paper 2010

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

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.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
