Vehicles waiting at the staging area will include automobiles, busses, vehicles pulling trailers, etc. Why can t vehicles travel through the tunnel on a first-come-first-served basis?
To enhance safety, vehicles will travel through the tunnel according to vehicle class. Each vehicle class will be metered into the tunnel at different time intervals (2.5 seconds to 45 seconds). The distance between commercial trucks will be greater than the distance between cars because commercial trucks have a greater potential fire load than cars. If a commercial truck were to catch fire, this distance would keep the fire from spreading to another truck in the tunnel. Busses also will travel through the tunnel at longer intervals because busses, like commercial trucks, have a greater potential fire load than cars. Also, the number of busses in the tunnel at any one time needs to be limited so there is always ample room in the safe houses if people must evacuate their vehicles.
