Red light running by Cyclists: Which factors influence the red light running by cyclists?

In an ideal world there would be no crashes in traffic. Unfortunately the real world is far from ideal and over 20,000 people get injured in a crash in the Netherlands each year. Around 46,7% of these registered crashes, take place at intersections. To decrease the chance and number of conflicts, and therefore the chance of crashes, many...

Dynamics and Control of a Steer-by-Wire Bicycle

Already for some time, electronic enhancements regarding vehicle behavior has made its way into the aviation and automotive industry by the term "by-wire" technology. Electronic sensors and actuators are used to replace traditional mechanical systems in which software is used to operate the actuators in a way that is not possible with...

Haptic feedback on the steering wheel to maximize front axle grip

Traditional Electronic Stability Control (ESC) systems influence planar vehicle motions to better match these to the driver’s intention. These systems use the Anti-lock Braking System (ABS) hardware to generate the needed tire forces. This has a large impact on longitudinal vehicle motions. A second method of altering the front wheel tire forces...

Rider Control Identification in Bicycling

Following in the wake of the increased bicycle popularity, bicycle research arose in the late 19th century. Early research, regarding the dynamic behavior of an uncontrolled bicycle, resulted in the Carvallo (1899) and more general Whipple (1899) model. In the past years, extensive research has been done to validate these uncontrolled bicycle...

Inventory of Bicycle Motion for the Design of a Bicycle Simulator

In the Netherlands most people have mastered riding a bicycle. Usually at the age of 4 a child learns to ride a bicycle. Few people however know how a bicycle actually works. A bicycle is a dynamic system that is more complex than one would expect. For example in order to go through a left curve on a bicycle one first has to steer right for a...
