Amoroso, Pedro (author), Vrcek, Aleks (author), de Rooij, Matthijn B. (author)This study introduces a method based on fine torque control to evaluate traction in rolling—liding line contacts under small slide-to-roll ratios (SRRs). To accomplish this, we engineered an innovative testing machine—a two-roller tribometer capable of precisely applying resisting torques to one of the rollers. Two types of tests were designed...journal article 2023

Chen, Tiantian (author), Ye, Shi (author), Oviedo-Trespalacios, O. (author), Sze, N. N. (author)With the increasing use of ride-hailing apps, concerns have arisen regarding road safety and driver distraction. Despite the recognized safety risks of driver distraction, limited research has explored how distractions from various ride-hailing systems affect drivers in the taxi industry. The research utilized a driving simulator experiment...conference paper 2023

Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)When the braking energy in electric transportation grids is not met by another vehicle's demand, it is either harvested by storage systems or wasted in braking resistors. This paper looks at three methods for increasing the amount of harvested braking energy without the use of expensive storage systems: decreasing the substation voltage,...conference paper 2023

Diab, I. (author), Saffirio, Alice (author), Chandra Mouli, G.R. (author), Bauer, P. (author)Solar PV systems have so far been the source of choice for the sustainable supply of urban electric transport networks—like trams and trolleybus grids. However, no consensus exists yet on the placement or sizing of PV systems at the traction substations, and no method is available for easy estimation of the PV system utilization performance....journal article 2023

Diab, I. (author), Saffirio, Alice (author), Chandra Mouli, G.R. (author), Tomar, Abhishek Singh (author), Bauer, P. (author)This paper offers a complete and verified model of DC trolleybus grids and examines the effect of the common modelling assumptions made in literature by using simulations, as well as bus and substation measurements from the grid of Arnhem, the Netherlands. An equivalent model for the overhead line impedance is offered taking into account the...journal article 2022

de Winter, J.C.F. (author), Saffarian, M (author), Senders, John W. (author)Objective: To share results of an experiment that used visual occlusion for a new purpose: inducing a waiting time. Background: Senders was a leading figure in human factors. In his research on the visual demands of driving, he used occlusion techniques. Methods: In a simulator experiment, we examined how drivers brake for different levels of...journal article 2022

Ali, Yasir (author), Haque, Md Mazharul (author), Zheng, Zuduo (author), Afghari, A.P. (author)Driver's response to a pedestrian crossing requires braking, whereby both excess and inadequate braking is directly associated with crash risk. The highly anticipated connected environment aims to increase drivers’ situational awareness by providing advanced information and assisting them during critical driving tasks such as braking....journal article 2022

de Winter, J.C.F. (author), Stanton, Neville (author), Eisma, Y.B. (author)The last decade has seen a surge of driving simulator research on automation-to-manual take-overs. In this commentary, we argue that most research within the take-over paradigm bears little resemblance to real automated driving. Furthermore, we claim that results within this paradigm could already be known based on published research from the...journal article 2021

Lee, J. (author), Mitici, M.A. (author)Aircraft maintenance is key for safe and efficient aircraft operations. While most studies propose cost-efficient maintenance strategies, the safety and efficiency of these strategies need to be quantified. This paper proposes a formal framework to assess the safety and efficiency of maintenance strategies by means of agent-based modelling,...journal article 2020

Scheepmaker, G.M. (author), Goverde, R.M.P. (author)Energy-efficient train control (EETC) has been studied a lot over the last decades, because it contributes to cost savings and reduction of CO<sub>2</sub> emissions. The aim of EETC is to minimize total traction energy consumption of a train run given the running time in the timetable. Most research is focused to apply mechanical braking on...journal article 2020

Pretagostini, Francesco (author), Ferranti, L. (author), Berardo, Giovanni (author), Ivanov, Valentin (author), Shyrokau, B. (author)Since their introduction, anti-lock braking systems (ABS) have mostly relied on heuristic, rule-based control strategies. ABS performance, however, can be significantly improved thanks to many recent technological developments. This work presents an extensive review of the state of the art to verify such a statement and quantify the benefits...journal article 2020

Mohammadnejad, Ali (author), Bahrami, Abbas (author), Goli, Majid (author), Dehbashi Nia, Hossein (author), Taheri, P. (author)This paper investigated a failure in a ventilated disc brake in an automobile. The failed brake disc had been in service for approximately 10 years. The observed failure was in the form of radial cracks that appeared to have initiated at the outer edge of the disc brake. The cracks were rather straight with no branching. Optical microscope,...journal article 2019

Negi, Naman Singh (author), van Leeuwen, P.M. (author), Happee, R. (author)This study is an extension of a previous work where differences between race-car drivers and normal drivers has been investigated in a high-speed driving task. The study focused on gaining knowledge about driver differences that can be helpful in designing an adaptive ADAS by introducing the driver into the control loop. The present study...conference paper 2019
