Knoop, V.L. (author), van Lint, J.W.C. (author), Yuan, K. (author), Zwaal, B.A. (author)In het Nederlandse wegverkeer is veel vertraging. Een vermindering van het verkeer zorgt ook voor een vermindering van die vertraging. Dit kan bereikt worden door maatregelen als beprijzing of spitsrechten. Het verkeerssysteem is één samenhangend systeem over grote afstanden. Om de effecten van deze maatregelen op netwerkschaal te beoordelen,...journal article 2021

Li, G. (author), Knoop, V.L. (author), van Lint, J.W.C. (author)Accurate and explainable short-term traffic forecasting is pivotal for making trustworthy decisions in advanced traffic control and guidance systems. Recently, deep learning approach, as a data-driven alternative to traffic flow model-based data assimilation and prediction methods, has become popular in this domain. Many of these deep learning...journal article 2021

Loder, Allister (author), Bressan, Lea (author), Wierbos, M.J. (author), Becker, Henrik (author), Emmonds, Andy (author), Obee, Martin (author), Knoop, V.L. (author), Menendez, Monica (author), Axhausen, Kay W. (author)Interactions among different modes or vehicle classes in urban road networks affect the network performance in different and complex ways. Thus, an answer to the question of “how many cars are too many for a city?” is not trivial. However, multi-modal macroscopic fundamental diagrams (MFD) offer a novel opportunity to answer this question. So...journal article 2021

Soldevila, Ignasi Echaniz (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)Traffic engineers rely on microscopic traffic models to design, plan, and operate a wide range of traffic applications. Recently, large data sets, yet incomplete and from small space regions, are becoming available thanks to technology improvements and governmental efforts. With this study we aim to gain new empirical insights into longitudinal...journal article 2021

Knoop, V.L. (author), Wierbos, M.J. (author), van Boggelen, Otto (author)Traffic flow might be limited by cross-traffic which has priority. A typical example of such a situation is a location where cyclists or pedestrians cross a stream of car traffic. Splitting the cross-traffic into two separate sub-streams (for instance left?right and right?left) can increase the capacity of the main stream. This is because it is...journal article 2021

Nagalur Subraveti, H.H.S. (author), Knoop, V.L. (author), van Arem, B. (author)Control measures at merging locations aimed at either the mainline traffic or on-ramp traffic do not lead to a fairness in the distribution of total delay across the two streams. This paper presents a control strategy of combining a lane change control with a ramp metering system at motorway merges. The control strategy presents the opportunity...journal article 2021

Keyvan-Ekbatani, Mehdi (author), Carlson, Rodrigo Castelan (author), Knoop, V.L. (author), Papageorgiou, Markos (author)Perimeter traffic flow control based on the macroscopic or network fundamental diagram provides the opportunity of operating an urban traffic network at its capacity. Because perimeter control operates on the basis of restricting inflow via reduced green times at selected entry (gated) links, vehicles on those links may be subject to queuing and...journal article 2021

Nagalur Subraveti, H.H.S. (author), Srivastava, Anupam (author), Ahn, Soyoung (author), Knoop, V.L. (author), van Arem, B. (author)This paper presents a novel approach to improve traffic throughput near diverge and weave bottlenecks in mixed traffic with human-driven vehicles (HDVs) and connected automated vehicles (CAVs). This is done by the strategic assignment of CAVs across lanes. The main principle is to induce strategic and necessary lane changes (LCs) (by CAVs and...journal article 2021

Klomp, Stefan R. (author), Knoop, V.L. (author), Taale, Henk (author), Hoogendoorn, S.P. (author)Freeway on-ramp areas are susceptible to traffic congestion during peak hours. To delay or prevent the onset of congestion, ramp metering can be applied. A Ramp Metering Installation (RMI) controls the inflow from the on-ramp to the main line so that the total flow can be kept just below capacity. Current ramp metering algorithms apply...journal article 2021

van Erp, P.B.C. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)Traffic flow can be described using three dimensions, i.e., space x, time t and cumulative flow N. This study considers estimating the cumulative flow over space and time, i.e., N(x,t), using relative flow data collected by stationary and moving observers. Stationary observers, e.g., loop-detectors, can observe flow at fixed position over...journal article 2020

Chen, Kaijia (author), Zhao, J. (author), Knoop, V.L. (author), Gao, Xing (author)Traffic throughput at intersections can be improved by using exit lanes for left-turning (EFL), tidal flow lanes near an intersection, which has been recently introduced. This paper considers the operational robustness of the EFL intersection in relation to the control scheme applied to the traffic light setting. For safety and efficiency, it...journal article 2020

Zhao, J. (author), Knoop, V.L. (author), Wang, Z. (author)Modeling traffic flow at intersections is essential for the design, control, and management of intersections. A challenging feature of microscopic modeling vehicular movement at intersections is that drivers can choose among an infinite number of alternative traveling paths and speeds. This makes it fundamentally different from structured...journal article 2020

van Erp, P.B.C. (author), Knoop, V.L. (author), Smits, Erik Sander (author), Tampère, Chris (author), Hoogendoorn, S.P. (author)Detector data can be used to construct cumulative flow curves, which in turn can be used to estimate the traffic state. However, this approach is subject to the cumulative error problem. Multiple studies propose to mitigate the cumulative error problem using probe trajectory data. These studies often assume “no overtaking” and thus that the...journal article 2020

Wierbos, M.J. (author), Knoop, V.L. (author), Hanseler, F.S. (author), Hoogendoorn, S.P. (author)Bicycles are gaining popularity as a mode of transport resulting in a mixed bicycle–car traffic situation on urban roads. Cyclists however, are hardly included in traffic flow models which complicates the design of safe and congestion-free traffic situations. This work introduces class-specific speed functions based on two variables, being space...journal article 2020

Nagalur Subraveti, H.H.S. (author), Knoop, V.L. (author), van Arem, B. (author)Lane drops are a common bottleneck source on motorway networks. Congestion sets in upstream of a lane drop as a result of the lane changing activity of merging vehicles. This causes the queue discharge rate at the bottleneck to decrease and drop below the capacity, leading to capacity drop and further congestion. The objective of this study is...journal article 2020

Wierbos, M.J. (author), Knoop, V.L. (author), Goni Ros, B. (author), Hoogendoorn, S.P. (author)An increasing number of people use the bicycle for urban trips resulting in local congestion at intersections, especially during peak hours. Understanding the queue dynamics is key to find the correct measures that can reduce the delays for cyclists without affecting other traffic modes. To this end, the discharge process of bicycle queues is...journal article 2020

Marika (author), Maaskant, Mark (author), Van der Meer, Evert-Jeen (author)An increasing amount of vehicles are equipped with driver assistance systems; many of the vehicles currently on the market can be optionally equipped with adaptive cruise control and lane centering systems. Using both systems at the same time brings the vehicle to SAE level-2 automation . This means a driver does not need to perform longitudinal...journal article 2019

(author)Cycling research at the operational behavioral level is limited, mainly because of the lack of empirical data. To overcome this data shortage, we performed a controlled, large-scale cycling experiment in the Netherlands. In this paper we describe the methodology for setting up and implementing such an experiment, from the motivation of its...journal article 2019
