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...

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...

Realistic microscopic traffic simulation is essential for prospective evaluation of the potential impacts of new traffic control strategies. Freeway corridors with interacting bottlenecks and dedicated lanes generate complex traffic flow phenomena and congestion patterns, which are difficult to reproduce with existing microscopic simulation...

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...

There is initial support for the effectiveness of approach-avoidance trainings in altering food-related health behaviors. Furthermore, outcome expectancies induced by verbal suggestions might optimize the effectiveness of these interventions, as shown in placebo research. The present study investigated the effectiveness of a gamified approach...

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...

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...

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...

Tactische rijadviezen hebben de potentie de doorstroming fors te verbeteren. In het project Dynamic Lane Guidance zijn hiervoor twee tools ontwikkeld en getest: een model dat de actuele verkeerstoestand schat en een algoritme dat naar patronen speurt.

With the use of Advanced Driver Assistance Systems (ADAS), traffic efficiency may be improved. This thesis presents an advisory system using advice on headway, speed and lane, in order to prevent potential problems 1-2km downstream. Current systems operate on smaller scale (e.g. Adaptive Cruise Control) or larger scale (e.g. route advice). With...

For a recently developed in-car speed, headway and lane use advisory system, this paper investigates empirically advice validity (advice given in correct traffic circumstances), credibility (advice logical to drivers) and frequency. The system has been developed to optimize traffic flow by giving advice on a tactical scale. This scale allows...

De beloftes zijn bekend: coöperatieve voertuig-wegkantsystemen zorgen voor betrouwbaardere reistijden, verhoogde verkeersveiligheid en verminderde emissies. Maar willen die beloftes ooit ingelost worden, dan is het niet voldoende om de boel technisch rond te krijgen. Een heldere en commercieel interessante product- en servicedefinitie is ten...

A new advisory ADAS system is implemented in micro simulation to asses the effects on traffic flow as well as on safety. The system uses loop detector data from which situations may be recognized where advices are given to drivers in-car. Advice is given on speed, headway and lane use. Effectively the system allows drivers to respond to...

This paper presents an extension of a microscopic freeway driver model for urban traffic. As urban traffic is more complex than freeway traffic, and because scientific models require extensive development, scientific models are often limited to freeways. For urban studies commercial software is often used. Models describing the behaviour in...

We experimentally validate a relatively recent electrokinetic formulation of the streaming potential (SP) coefficient as developed by Pride (1994). The start of our investigation focuses on the streaming potential coefficient, which gives rise to the coupling of mechanical and electromagnetic fields. It is found that the theoretical amplitude...
