For improving the performance of ADAS and AD system in China, driving behavior Chinese drivers is being increasingly focused. The purpose this study to investigate macroscopic microscopic characteristics typical behavior, by using UAV capture extract them. Traffic flow rate, traffic density, velocity, acceleration offset from lane center were acquired their influence vehicle types studied. Mini...

FEOD (Finite Element Optimization Design) is a design methodology that derives optimal design solutions by concurrently considering various mutually dependent design elements from an assortment of disciplines. As such, it is applicable to the designing of cars. This paper is concerned with design optimization of material reinforcement of car body frame for rigidity improvement. Topology optimiz...

A study was conducted to find out whether in a rear-impact motor vehicle accident, velocity changes in the impact vehicle of between 10 and 15 km/h can cause so-called "whiplash injuries". An assessment of the actual injury mechanism of such whiplash injuries and comparison of vehicle rear-end collisions with amusement park bumper car collisions was also carried out. The study was based on expe...

Laboratory studies have suggested that the preferred cadence of walking is approximately 120 steps/min, and the vertical acceleration of the head exhibits a dominant peak at this step frequency (2 Hz). These studies have been limited to short periods of walking along a predetermined path or on a treadmill, and whether such a highly tuned frequency of movement can be generalized to all forms of ...

Gonadectomized male golden-mantled ground squirrels ( Spermophilus lateralis) were implanted with estradiol benzoate (EB)-filled or empty capsules. Body mass was monitored before, during, and for at least 1 yr after hormone treatment. EB treatment during the mass-gain phase of the annual cycle significantly decelerated increases in body mass; the period of the circannual rhythm (CAR) of body ma...

Although a substantial body of research concurs that most urban areas have a challenge in providing adequate car parking space, there is a scarcity in the literature on how conformity to planning standards that regulates the provision of car parking spaces may be analyzed. This study, therefore, examines the extent to which the planning standards that regulate compliance with the provision of c...
