Flow Systems are challenging for cities

A major challenge in designing a contemporary city is to deal with the huge flow systems. For instance today I measured the sound level at a bus stop in Northern Stockholm. If it had been a work place it would have been requiring hearing protection and limited times of exposure. The sound level was equal to that of operating a chain saw. And what if a workplace should have 1-2 ton objects, passing by you within 50 cm at 70 km/h? Without any protection?

I think we seriously need to rethink and and rework the flow systems.
