Where is the fire exit of the pedestrian street?

The pedestrian street is set with fire exits every 50 meters, and each street is 3 meters wide. According to relevant public information, there are two kinds of fire exits, horizontal and vertical, especially in high-rise buildings. The exits separated by fire doors and possible fire points can be called fire exits, where there are full-time and part-time jobs. For buildings, there will also be outdoor fire stairs. In American TV series, the man jumps high in a secluded alley, climbs a simple staircase made of steel, and then quietly enters through the window of the woman's boudoir. That's the safety exit.
