Origin and Destination Study Origin and Destination Study TEEI (Civil/Environmental) (OP) 10 Feb 06 15:19 Can anybody explain me the procedure to conduct an Origin and Destination Study in a Downtown district? Thanks RE: Origin and Destination Study francesca (Civil/Environmental) 15 Feb 06 12:25 There are two methods, one is to interview people and the other is to observe on a cordon. If you observe on a cordon, then you can have people or you can do a licence plate survey by video camera. The latter are usually contracted out to experts. (For instance, Count on Us are a UK firm specializing in traffic count surveys.)Is downtown one of the origins/destinations? Or are all origins and destinations downtown?
