  1. In Sweden they are almost always both. That is both before the crossing as well as after. Specially how when its all LED, the back side of the on across the street is the front side of there light on there side.. That is not always the case, but its pretty common

  2. Roundabouts is not always the best option. I would say roundabouts should only be used on road with equal traffic on all sides. If one road have much more traffic than the road crossing, it should be made into a main road.

  3. That is not really true. The fact is that most of the cities and towns are built very recently. Also, carts did exist before the car did. Roads was mostly made for carts, not pedestrians. I live in Sweden, if i look at my town 1.4km2 was built prior to WW2. The town is currently 13.5km2. To get it into perspective 0.5km2 was built the last 10 years. The village where i live was 0.01km2 before WW2, and is currently 0.7km2, that of 0.25km2 have been built the last 2½ years. To many people go to Berlin, or Paris, or Rom and imagine that is how Europe looks. It mostly don´t. Specially not in Central and Northern Europe. For instance, Paris and Stockholm have about the same urban area. En Paris there live about 10 million people inside the urban area (not counting metro area), in Stockholm there live about 2.1M people in the Urban area (not counting metro area). Typical of most Northern European citis and town having a dense core, that is really very very dense, but then just loads of suburba around it. In Stockholm they even have suburbia between the project suburbs. Downtown there are more tourist then people that actually live there. Really quite a lot more. But people that come visit pretty much never see that. Even people that live in the city as like a guest worker, might live there for 5-10 years and don´t have a clue that there exist giant suburbia areas. Sweden may be the most extreme example of this in Europe, but its very much true in Finland and also in Norway and Denmark to a sightly lower degree. Its also true in Germany, similar to Denmark. I have lived in Germany in a town that is very similar to the Swedish town i live in now. Its also true to e degree in Italy, maybe not so much in Rome, but a larger degree in say Milano. On the same token the opposite is also true to a degree.. There are towns and cities in the US with a similarly dense city core. Those are of cause mostly on the east coast. Its really more the event of railroad that spreed them out more so than cars

  4.  @melnerud  They just fit them on the back side. We have special lights that are independantly coneted frontside to backside.

  5. You shouldn´t do that. The road engineere have put the stop line on a optimal distance from the crossing

  6.  @srkares  i just lean forward

  7. Roundabouts are good if the roads is on equal size, other vice its not. If they are not equal size a main road system should be used. And of cause, if the roads are very smal nothing is really needed. There is reallt few cases where traffic light are the most efficent.

  8.  @ac1455  Most of what would become streetcars later was originaly made as local railroads. They was typically converted to streetcars first in a period between 1880 to 1900. I know my university town had local railways all around the city core with full scale (more or less) steam engine sin the 1860s. I don´t know the number of people that was run over, but it was probobly more than one. Those railroads was converted to trams around the turn of the century. It probobly was somewhat of a gradual process when the locos was replaced by tram-locos and the line was electrified with DC current. That did happen before the mainline was electrified (i know they was running electric trams at least in 1902) that was and the mainline was probobly electrified around 1912, that was fairly early, even in European terms.

  9.  @Lewtable  its rather the width and length of the carts that is the issue. Remeber. People in olden days eate no less than we do. A single horse cart is about 2 Metes wide, and 8 meters long and can carry up to 1.5 ton, but often less. A moden 3 axle tryck is 10 meters long and 2.5 meters wide. That is, slightly larger, and can carry 15 tons. So despite popular belife there was loads of traffic in olden times.

  10. Biking is not reallt a problem if it -20. It is a problem when its close to 0C

  11. 6:40 Its not quite true. Some crossings have just a yeald sign of you go right, its not very common, but there are at some places
