Abstract

[CATALÀ] Cada dia per anar de casa al treball haig de circular de mitjana per 11 rotondes, em permet sentir el tediós que resulta haver d'aturar-se de forma brusca és degut a la poca visibilitat d'aquestes i la imprevisibilitat de les traçades d'alguns conductors. Això provoca que a més de fer un consum superior innecessari de frens també ho fem de combustible per introduir-nos a la rotonda, en alguns casos accelerant amb la mateixa innecessària violència. Tots dos casos generen la majoria de partícules contaminants a l’aire de les ciutats. També pretén evitar els accidents derivats d’aquests actes. El meu objectiu tracta d'evitar aquestes situacions, sent les mesures aplicables de forma immediata, senzilla i econòmica. La rotonda intel·ligent té un grup de sensors electromagnètics capaços de detectar velocitat i dimensions, a més porta instal·lats senyals de velocitat lluminoses programables que indicaran la velocitat que els vehicles hauran de circular per fer una entrada a la rotonda de la forma més eficient possible. Els coneixements que he adquirit durant el grau em permet fer ús del software LabVIEW per a programar el control i un simulador que sigui capaç de mostrar el funcionament. El control ha sigut satisfactori amb una freqüència de 2160 vehicles per hora, aquesta freqüència és considerada baixa. La simulació i el control aplicat té un error de ± 2,23 metres, aquest error en un control real pot ser eliminat, considerant que un humà és capaç de rectificar aquesta variació considero que és assumible.

[ANGLÈS] Every single day to go from home to work, I have to drive on average through 11 roundabouts. It allows me to feel how much cumbersome is to stop brusquely because of the low visibility or the unpredictability of the traces of “some drivers”. In addition to unnecessary braking, we also use too much fuel to speed up enough to go inside, in some cases with the same unnecessary violence. Both cases generate the majority of environmental pollution in cities. It also aims to avoid accidents arising from these acts. My objective is to avoid these situations, being the measures applicable immediately, simply and economically. Smart roundabout has a group of electromagnetic loops sensors capable of detecting speed and size installed about 30 meters away. Also, has installed programmable luminous speed signals that indicate the speed that the vehicles will have to circulate with to make the entrance as efficient as possible. The knowledge I have acquired during the degree allows me to choose the LabVIEW software to program the control and a simulator capable of showing the behaviour. The control has been satisfactory with a vehicle frequency of 2160 per hour, it’s considered low. The simulation and the applied control has an error of ± 2,23 meters, this can be eliminated in a real control, considering that a person is able to rectify this variation I consider that it is acceptable.
