One of the major reasons for accidents is speed. Top of Form Inappropriate speed has been identified as the most important causal factor for serious traffic accidents. Traffic calming measures (TCMs) are engineering measures that are widely implemented to improve road safety by considerably reducing vehicle speed. TCMs have been widely used in urban areas to reduce vehicle flow rat...

Abstract In this study, the results of a vast experimental campaign on applicability smartphone-based technique for bridge monitoring are presented. Specifically, vehicle–bridge interaction (VBI)-based approach is exploited as cost-effective means to estimate natural frequencies bridges, with final aim possibly developing low-cost and diffused infrastructure system. The analysis performed using...

objectives the aim of this study was to examine temporal changes in technical and physical performances during a small-sided game (ssg) in elite soccer players. methods sixty elite youth players (age 14.8 ± 0.2 yr; stature 177 ± 5 cm; body mass 66.2 ± 4.7 kg) completed a 5 v 5 ssg using two repetitions of 8 minutes interspersed by 3 minutes of passive recovery. to evaluate temporal changes in p...

In urban areas, drivers often have difficulty detecting pedestrians who want to cross the street but are obstructed by parked vehicles. Highly automated vehicles (HAVs, SAE Level 4) will solve this issue automatically and at least as safely human drivers. We conducted two studies investigate whether passengers’ trust in automation can be supported adapting HAV driving behavior demonstrate that ...

The Royal Netherlands Meteorological Institute has continuously operated an outdoor atmospheric infrasound array containing 37 pairs of particle velocity sensors (Microflown) and 6 pressure sensors in the north of the Netherlands in the fall of 2008. As initial results, we detected transients caused by distant aircrafts and calculated their Direction of Arrival (DOA). A nearby sound-source, pro...

Autonomous navigation is a complex task that requires both sensing capabilities to react to sudden environmental changes or map the environment and reasoning to schedule the next action to perform. Starting from basic sensing technology used in the majority of mobile robotic systems, the introduction of sensor fusion techniques allows to obtain useful information to solve the localization, mapp...

The flexible structure of the new type aerial track studied in this paper is formed by strings and tracks, which have obvious dynamic characteristics under action vehicle moving loads also an important factor affecting its performance. uses full-scale model AERORail, based on modal test a specific span, combined with fundamental frequency analysis structure, carries out load to determine change...

Intersections in the urban network are potential sources of traffic flow inefficiency. Existing intersection control mostly adopts “cross” pattern model, while use roundabout circular is rather sparse. Connected and autonomous vehicle (CAV) technologies can enable roundabouts to better compete with traditional designs terms performance. This study proposes a strategy for CAVs enhance performanc...

This paper describes behavior and testing of the vehicles set up by VisLab to cover, in autonomous mode, a long 13.000 km trip from Italy to China, passing through Moscow. The paper, begins with a short description of the hardware and focuses on the vehicle behavior, what kind of situations is able to negotiate and how they are managed. A description of how the system has been tested and how it...

We begin with Atmosphere Einstein Brownian motions toward Knudsen Gas Boltzmann Kinetic formulism of the fluctuation-dissipation theory and applied to space travelers reentry vehicles. Early experimental results are estimated on worst situation upper bound when a vehicle is frictionally passing through dense atmosphere. In reality, has spent more time in dilute atmosphere space. Accordingly, fl...
