Are there case studies pertaining to two egress discharges being too close to each other? My situation is an outdoor area with alleyways as egress discharge. There is one contained area (an outdoor dock) with the two egress discharges but they are very close, within 20' of each other bot at the end where the dock meets land and there is a building between. They open into more small pathways and there is a lot of potential for people to run into each other, trampling, and I'm guessing they could impede people from the other egress from being able to escape. If anyone has some experience with this or case studies, I would very much appreciate your knowledge.
