Am gasit pe FB un clip interesant in care se prezinta mai multe tipuri de intersectii si valoarea de trafic per minut. Am decis sa o postez aici pentru cei interesati de subiect, si am extras mai jos in tabel datele prezentate in clip pentru o mai usoara comparatie.

„Filmuletul respectiv a fost facut in jocul Cities: Skylines. Simularile de trafic sunt capacitatile calculate de simulatorul jocului, care clar nu e facut cu scopuri practice sau stiintifice. Chestia e ca simulatorul este bazat pe un automat celular, o metoda care e folosita pe scara larga si de simularile reale de trafic.

In cifre absolute, e clar ca cifrele sunt supra-estimate cu pana la mult peste un ordin de marime (de zeci ori mai mari adica – cifrele sunt vehicule (din joc) pe minut. Se si vede ochiometric – daca va uitati cu atentie la vehicule, sunt mult mai rapide si mult mai agile decat orice vehicul real (si se inghesuie in feluri care in realitate ar provoca accidente; in unele cazuri detectia de coliziune nu functioneaza, si vehicule trec „prin altele” fara probleme, de exemplu autobuzul rosu la 0:04).

Animatia este insa ok ca ilustrare rapida a tipurilor de intersectii reale care exista, si o ilustrare extrem de grosiera a capacitatii fiecarui tip de intersectie relativ la alte intersectii. Dar, un stack are de vreo 25-30 de ori capacitatea unei intersectii la nivel nesemaforizata, nu doar de 5 ori cum indica jocul.” spune veteranul user frunzaverde de pe forumul peundemerg.ro
