In this short paper we address the problem of abrupt breakdowns in traffic flow as a consequence of high traffic demand in combination with small driver inaccuracies. First we provide a brief overview on a Cooperative Advanced Driver Assistance System (CADAS) called Density Redistribution through Intelligent Velocity Estimation (DRIVE) that has been proposed to mitigate jam formations. Next, we...

The car following model is a key element in driver behavior modeling. A PD controller car-following model is a popular and realistic model. A big problem met in designing driver behavior models is the absence of reliable data from the real traffic. However, experiments using an instrumented vehicle driven in the real world supplied the radar tracking data. This paper first analyzes the desired ...

Many traffic problems occur on urban intersections. Advanced Driver Assistance Systems aim to solve these problems. However, their effects cannot be deduced directly from observing normal driving behavior, because adding a system alters the driving task. A model must be used to represent both normal intersection driving and interaction with ADAS. By using the structure of the driving task, it b...

Accurate driver and package models are necessary to analyze the signal integrity (SI) and electromagnetic compatibility (EMC) issues on digital circuits. 2-wire models that assume an ideal power distribution system (PDS) are commonly used in modeling the SI of signal lines. This assumption makes real SI and EMC analysis worthless or at least only useful under certain restrictions. In order to a...

There appears to be a lack of new ideas in driver behavior modeling. Although behavioral research is under some pressure, it seems too facile to attribute this deplorable state of affairs only to a lack of research funds. In my opinion the causal chain may well run in the opposite direction. An analysis of what is wrong has led me to the conclusion that human factors research in the area of dri...

A high-energy supercontinuum spanning 4.7 octaves, from 250 to 6500 nm, is generated using a 0.3-TW, 3.9-μm output of a mid-infrared optical parametric chirped-pulse amplifier as a driver inducing a laser filament in the air. The high-frequency wing of the supercontinuum spectrum is enhanced by odd-order optical harmonics of the mid-infrared driver. Optical harmonics up to the 15th order are ob...

This paper describes recent advances in the analysis and classification of driver behavior in actual driving scenarios. We employ data obtained from the UTDrive corpus to model driving behavior and to detect if distraction due to secondary tasks is present. Hidden Markov Models (HMMs) are used to capture the sequence of driving characteristics acquired from the vehicle’s CAN-Bus (Controller Are...

This contribution deals with the implementation of an automated cognitive-based supervision concept applied for the first time on a real vehicle. Here, the Situation-Operator-Modeling (SOM) approach is used as a representational concept to model and formalize the logic of interaction between driver, vehicle, and environment based on sensor and video measurements. The programmed implementation o...

This paper presents an overview of recent advances on modeling and layout optimization of devices and interconnects for high-performance VLSI circuit design under the deep submicron technology. First, we review a number of interconnect and driver/gate delay models, which are most useful to guide the layout optimization. Then, we summarize the available performance optimization techniques for VL...

Modern cars contain increasingly complex driver information systems. To handle such a system in a safe and comfortable way new approaches for in-car user interfaces have to be developed. A special focus lies on speech input because it promises the most comfortable operation of the system without distracting the driver from traffic. But because speech input is not reliable enough, an error manag...
