Raju, Narayana (author), Schakel, W.J. (author), Reddy, N. (author), Dong, Y. (author), Farah, H. (author)Automated driving systems, which can take over certain dynamic driving tasks from the driver, are becoming increasingly available in commercial vehicles. One of these automated driving systems widely introduced in commercial vehicles is Adaptive Cruise Control (ACC). This system is designed to maintain certain desired driving speeds and time...journal article 2022

Calvert, S.C. (author), Schakel, W.J. (author), van Lint, J.W.C. (author)The inclusion of human factors (HF) in mathematical models is proving crucial to allow complex driving behaviour and interactions to be explicitly considered to capture driving phenomena. An important area where such integration is required is for the role of anticipation by drivers to compensate for critical traffic situations. In this paper...journal article 2020

Fernández-Dacosta, Cora (author), Shen, Li (author), Schakel, Wouter (author), Ramirez, Andrea (author), Kramer, Gert Jan (author)The deployment of low-emission alternative fuels is crucial to decarbonise the transport sector. A number of alternatives like hydrogen or dimethyl ether/methanol synthesised using CO<sub>2</sub> as feedstock for fuel production (hereafter refer to “CO<sub>2</sub>-based fuels”) have been proposed to combat climate change. However, the...journal article 2019

(author)Sags are roadway sections along which the gradient increases gradually in the direction of traffic. Sags are generally bottlenecks in freeway networks. Previous research suggests that traffic management measures using advanced Adaptive Cruise Control (ACC) systems could reduce congestion on freeways, but little is known about their potential...journal article 2019

Calvert, S.C. (author), Schakel, W.J. (author), van Arem, B. (author)With automated and cooperative driving making its breakthrough, and related systems in fast development, their future influence and impact on roads and traffic may be extensive. Truck platooning is such an application that relies on the development of Cooperative Adaptive Cruise Control (CACC) and is said to be practice ready. While the main...journal article 2019

Xiao, L. (author), Wang, M. (author), Schakel, W.J. (author), van Arem, B. (author)Cooperative Adaptive Cruise Control (CACC) systems have the potential to increase roadway capacity and mitigate traffic congestion thanks to the short following distance enabled by inter-vehicle communication. However, due to limitations in acceleration and deceleration capabilities of CACC systems, deactivation and switch to ACC or human...journal article 2018

Schakel, Wouter (author), Hung, Christine Roxanne (author), Tokheim, Lars Andre (author), Strømman, Anders Hammer (author), Worrell, Ernst (author), Ramirez, Andrea (author)Calcium looping CO<sub>2</sub> capture is a promising technology to reduce CO<sub>2</sub> emissions from cement production. Coal has been seen as a logical choice of fuel to drive the calcium looping process as coal is already the primary fuel used to produce cement. This study assesses the impact of using different fuels, namely coal,...journal article 2018

Schakel, W.J. (author), Gorter, C.M. (author), de Winter, J.C.F. (author), van Arem, B. (author)With the increasing number of vehicles equipped with Adaptive Cruise Control (ACC), it becomes important to assess its impact on traffic flow efficiency, in particular with respect to capacity and queue discharge rate. Simulation studies and surveys suggest that ACC has both positive and negative effects on traffic flow, but empirical...journal article 2017

Calvert, S.C. (author), Schakel, W.J. (author), van Lint, J.W.C. (author)With low-level vehicle automation already available, there is a necessity to estimate its effects on traffic flow, especially if these could be negative. A long gradual transitionwill occur frommanual driving to automateddriving, inwhichmany yet unknown traffic flow dynamics will be present. These effects have the potential to increasingly...journal article 2017

de Winter, J.C.F. (author), Gorter, C.M. (author), Schakel, W.J. (author), van Arem, B. (author)Objective: Adaptive cruise control (ACC), a technology that allows for automated car following, is becoming increasingly prevalent. Previous surveys have shown that drivers generally regard ACC as pleasant but that they have to intervene when the ACC reaches its operational limits. The former research has been mostly concerned with specific car...journal article 2017
