Interpretation of flexible cycling behavior has always been a tough task. It is meaningful to understand the overtaking cyclists for its threats safety and high frequency on shared roads. Advanced unsupervised nonparametric clustering methods are compared distinguish segments from whole trajectory based characteristics nonmotorized two-wheelers, while hierarchical Dirichlet process hidden Marko...

The assistance and autonomous performance of overtaking manoeuvres can offer significant safety benefits. impact driving context on perceived risk emphasises the benefits using contextual information to adjust manoeuvring behaviour. This paper follows a mixed approach, addressing two main objectives: identifying factor combinations related crashes (objective risk) exploring their relationship r...

In the article, three types of proximity sensors that might be used in bicycle rangefinder to measure distance between and an overtaking car are compared. The influence various factors on accuracy measurements obtained using ultrasonic, infrared laser is tested, among others, light conditions, surface type colour, rain, pollination vibrations.

Despite continued worldwide chaos brought about by challenged economies and global terrorist actions, e-commerce continues to grow in import for all regions of the world. B2B sales were approaching 1US trillion worldwide by year-end. Worldwide holiday sales were expected to double from 2001, with Europe sales overtaking those in the US. B2C sales, while expanding, were challenged and may near 0...

In a random-matching economy of traders who maximize cumulative consumption (overtaking criterion), the stationary, Markov, Bayesian-perfect equilibrium is studied. At such equilibrium, two results hold: (1) perfect substitutability between current and future consumption implies a no-surplus condition; and (2) by the no-surplus condition, there is a nominal price at which all trades must occur....

The first sources of ionizing radiation to condense out of the dark and neutral IGM sent ionization fronts sweeping outward through their surroundings, overtaking other condensed objects and photoevaporating them. This feedback of universal reionization on cosmic structure formation is demonstrated here by gas dynamical simulations, including radiative transfer, for a cosmological minihalo of d...
