Highly automated vehicles (HAVs) have been introduced to the transportation system for purpose of providing safer mobility. Considering expected long co-existence period HAVs and human-driven (HDVs), safety operation interacting with HDVs needs be verified. To achieve this, HAVs' Operational Design Domain (ODD) identified under scenario-based testing framework. In this study, a novel framework aiming at identifying Safety performance boundary (SPB) is proposed, which assures coverage...

Autonomous vehicles (AVs) are being introduced to the traffic system with promise of improving current status. However, empirical data also indicate contrary effects estimated higher crash rate and change patterns. Therefore, it is necessary investigate driving behavior AVs human-driven (HDVs) in real mixed traffic. Current studies have analyzed HDVs, as well behavioral adaptations drivers HDVs based on data. While they play an important role systems, signalized intersections not been...

Abstract In this paper, a radio frequency sensor for measuring microfluidics dielectric properties is designed based on microstrip meander line. The replaces the straight transmission lines with in part of half-wavelength path difference to improve sensitivity and reduce its size. According experimental results, line has higher accuracy lower relative error than methanol–ethanol mixtures different molar fractions. measured by after calibration an adjustable cavity less 1%. It easier detect...

A new flexible broadcast optical switching structure (FBOSS) using tunable splitter is proposed. FBOSS supports both point-to-point and point-to-multipoint (broadcasting) connections, any input signal can be broadcasted to number of output ports without extra power loss. Its flexibilities the port wavelength help enhance capability switching.
