Loved all the questions (Workers & Resources: Soviet Republic)

Salute guys. Enough enough time in this game but still have questions:
1. How do you calculate the number of workers on the job. I already took everything into calculation, 3 to 6 shifts.
Here primr on the screen. A fairly large city in compliance with all requirements of the population. Each house has a designated place of work and balanced percentage. Every coal mine has 4 in-house 100% (400чел/250мест in theory) in fact there are only 40-70 works. The same situation with all the buildings in the city. What's the matter ? In statistics writes that the unemployed 1K, and productivity of 92%.





2. Also for appointment to a particular place of work, after more time the whole house in red disadvantages (all they need within walking distance up to 100m) indicators of contentment filled almost to the maximum.




3. I have the whole city 3 hospitals, each according to my logic had to answer for his plot, but the game says I'm a fool and now their cars drive great distances to visit each other. In the screenshot for example of the Donetsk and the town and the opposite travel of the carriage, as shown, they almost reach the city and frequently takes place, probably due to the fact that who was driving was already dead. + fuel consumption hard. How to configure it ?




4. The problem with the intersection of railway and road. Why is she blocked ? How to avoid it ?
