What employees do today because of their experience yesterday: Previous exposure to yellow:number aspects as a cause for SPAD incidents

When a train passes a red aspect, this is called a Signal Passed at Danger event or SPAD. Sometimes it is easy to identify the SPAD cause but in other cases it is unclear why the incident occurred, especially if the system operated as usual and the train driver was trained and experienced just like his or her colleagues. In previous research,...

Driving simulators as training and evaluation tools: Novice drivers’

The Problem. We know that newly-licensed 16 and 17 year old drivers during their first six months on the road with a restricted license are at a greatly inflated risk of crashing. This inflated crash rate has not changed over the last 50 years. The Question. The question we address is whether there are training techniques that show some promise...

Impacts of a Congestion Assistant on driving behaviour and acceptance using a driving simulator

In-vehicle systems that assist the driver with his driving task are developed and introduced to the market at increasing rate. Drivers may be supported during congested traffic conditions by a so-called Congestion Assistant consisting of a mix of informing, assisting and controlling functions. This paper describes the impacts of the Congestion...

Adaptive importance sampling for probabilistic validation of advanced driver assistance systems

We present an approach for validation of advanced driver assistance systems, based on randomized algorithms. The new method consists of an iterative randomized simulation using adaptive importance sampling. The randomized algorithm is more efficient than conventional simulation techniques. The importance sampling pdf is estimated by a kernel...

Vibrotactile in-vehicle navigation system

A vibrotactile display, consisting ofeight vibrating elements or tactors mounted in a driver's seat, was tested in a driving simulator. Participants drove with visual, tactile and multimodal navigation displays through a built-up area. Workload and the reaction time to navigation messages were measured for normal and high workload conditions....

Opportunities for technology supported driver training [Kansen voor een technologie-ondersteunde rijopleiding]

Purpose. Driver education programs in the Netherlands focus on practical lessons on the vehicle, under supervision of the instructor. An important drawback is that the driving instructor has limited control over the learning environment. Opportunities for instruction depend on incidental events taking place in actual traffic. Advanced training...

Modeling motorway driving behavior

Microscopic traffic simulation constitutes a useful method for predicting the effects of new transport telematic systems in road traffic. In such a model, the driver model is a key element describing the dynamic individual driving behavior in relation to the vehicle, the road environment, and other traffic participants. The driver model...

Speed choice and steering behavior in curve driving

The relation between speed choice and steering performance during curve negotiation was studied in a driving simulator. The hypothesis was that curve radius and steering competence both affect steering error during curve driving, resulting in compensatory speed choice. In this, the control of safety margins was assumed to operate as a regulatory...

Driving simulator validity: Some considerations

The validity of driving simulators for behavioral research is discussed. The concept of validity is introduced and explained, and a survey of validation studies follows, in the TNO driving simulator and others, comparing field and simulator study results. Results for mid-level driving simulators show that generally absolute validity of route...
