This research proposes a method to create an objective comfort index for public transportation and suggests the use of low cost technology to acquire the required data. A case study of Montreal showcase the approach for two key indicators: vehicle's vibrations, and noise levels. Cross comparisons to London (U.K.) and Santo Domingo (Dominican Republic) were used to characterize the degree of comfort...
The right-of-way conflict such as lane-merging problem between Autonomous Vehicles (AVs) is an inescapable issue. Related studies formalize the problem using centralized decision-making models of “Reservation” or “Auction” from the perspective of intersection management, that are suitable only for the scenarios with a centralized intersection agent; and the fiat currency spent on bidding may trigger...
In this paper, in order to study the equivalent simplified model of multi-layer vertical isolation structure under heavy load train vibration, the two degree of freedom simplified calculation model of the multi-layer isolated structure is presented based on the equivalent principle of the first two order frequency and the total axial force. Based on the theoretical analysis, the equations of motion...
