 Based on the results I obtained from the different settings, the following setting seems to reduce cars' waiting times to minimum:
 * tram lights - '''60s'''
-* car lights for Bělehradská street - '''10s'''
+* car lights for Bělehradská street - '''5s'''
-* car lights for Anglická street - '''10s'''
+* car lights for Anglická street - '''15s'''
 These results show, that the intersection is not set optimally regarding the waiting times of the cars.

		+	For the purpose of this simulation, I simplified the intersection. NetLogo world size was set to {{-15,..,15},{-15,..,15}} and the intersection is placed in the middle, as you can see in the following picture.
		+
		+	Black color displays the roads where cars drive. Blue color signifies tram rail. The arrows point to the direction in which cars or trams go.

		+
		+	* Vast majority of the cars coming from Bělehradská street turn left to Anglická street. The number of cars continuing straight to Škrétova street is so small, that all the cars in the simulation turn left to Anglická street.
		+	* Similarly as mentioned above, almost none of the cars coming from Anglická street turn right to Škrétova street. As visible on the map of the intersection, there is an extra line solely for cars turning right. But for the purpose of this simulation, this line has no importance, and thus was omitted.
		+	* Because the roads are full, the cars don't change lines. Thus, this simulation doesn't allow the cars to change lines.
		+	* The light are set and are not dependent on whether there are any pedestrians or not. Therefore, pedestrians were not included in the simulation as they are not important for it's purpose.
		+	* There is limited space for the cars going to Anglická street. This led to the choice that the time of green lights from both sides should stay the same - this means that I kept the time of green light for trams (= red lights for all cars) the unchanged.
