Less automation and full autonomy in aviation, dilemma or conundrum?
The two recent fatal accidents involving the brand new Boeing 737 Max 8 fourth generation airplane reignited the discussions on the suitability of the increasing aircraft automation levels. Although the data presented in this study demonstrate that the automation phenomenon increased flight safety, some relevant research indicates that high levels of automation may have undesirable outcomes, and contribute for the increment of accidents rates. Such discussions arise in a moment when the autonomy phenomenon has its dawn within the aviation domain and, thus this paper aims at presenting and discussing some key information related to the automation and the autonomy phenomena within the aviation domain.
There are some problems in the timing distribution and operation mode of the crossroads traffic lights,such as some blind spots in traffic guidance,and different traffic streams with simultaneous passage time in each phase.A real time traffic guidance of traffic lights to traffic states which is accomplished between real time guage of traffic density and real time traffic states is designed in this paper as a solution to the above traffic problems.Singlechip AT89C51 is used for the dealing of detected signals.This real time traffic lights system design aims to improve intersection traffic conditions.
