Homework Statement
Consider a one-way road where the cars form a PP(lambda) with rate lambda cars/sec. The road is x feet wide. A pedestrian, who walks at a speed of u feet/sec, will cross the road if and only if she is certain that no cars will cross the pedestrian crossing while she is on it. Shwo that the expected time until she completes the crossing is (ex/u -1)/lambda
I know we need x/u seconds to cross, but I really don't even know how to start it :/ Will we use the erlang distribution?
