One Way Traffic Seperation Scheme?

Question

Has any one any idea on whether there are any shipping lanes that are made one way, in which the flow of traffic is alternated every so often. e.g. north - south from 0000 to 1200 and south - North 1200 - 0000.

Looking at it for an assignment on traffic managment of the Turkish straits where there is sometimes a delay of 18hours, so a scheme such as this may reduce such waiting times.

Answer 1

Along with the canals that have been mentioned, the entrance to Pusan, South Korea is alternating. This is based more of the pilots schedules. Usually along the lines of outbound from about 0600-0800, inbound 1000-1200, etc.

Answer 2

As far as I'm aware, there's nowhere where they direction reverses by the clock - what would happen to a ship part way along, would it have to turn around?

There are certainly Traffic Separation Schemes in the English Channel, but they're directional, not time based. You can see some on : http://www.mcga.gov.uk/c4mca/mcga-hmcg_rescue/channel_navigation_information_service_(cnis)/dops_-_dover_strait_tss_chartlet.htm.

The closest I can come to a time-based scheme is that operated in the Suez Canal, where shipping travels in convoys. On a typical day, three convoys transit the canal, two southbound and one northbound. The first southbound convoy enters the canal in the early morning hours and proceeds to the Great Bitter Lake, where the ships anchor out of the fairway and await the passage of the northbound convoy. The northbound convoy passes the second southbound convoy, which moors to the canal bank in a by-pass, in the vicinity of El Qantara.

Hope this is some help.

Answer 3

Where you enter the Chesapeake Bay, there is a Bay-Tunnel Bridge. There are 2 tunnels, and the ships pass over them in one way traffic. If you are going into the Bay, north, you take the Eastern route. Going south out of the Bay takes the Western route.

Answer 4

Not in my offshore marine waters. Not enough traffic I suppose. Don't put myself in front of the big fast movers
often. Not certain how enforcement could be handled in
more vessel rich traffic locations such as inland waterway
or ports. I'm more focused on tidal times than scheduled
arrival/departure.

Answer 5

As far as I know there is no one way traffic in the Dardanelles, however in the Bosporus there is a scheme for larger vessels that alternates. When I went through in 2003 we had to await a convoy at Istanbul, however smaller vessels can overtake in certain sections.

Answer 6

the Suez Canal has done alternating one way traffic almost from the beginning way back when.........

Panama is doing it now on a ship by ship basis getting Panamax thru Galliard Cut........

off hand though I cant think of any TSS that reverse depending on the hour.........most schemes have lanes that are ALWAYS one way...........for those Captains who read charts.......

try looking at Panama and Suez Canals web sights, or the US or British Sailing Directions.......or maybe the IMO (www.imo.org) has something useful.......that would be a first for them......

Answer 7

Not heard of anything but tidal effects may also determone which way the traffic flows at certain times.

Answer 8

I suggest that you 'go ogle' - 'Rotterdam Harbor, Holland'
It is the heaviest trafficked ship harbor in the world and they do exactly what you are describing as 'ship traffic management' and they do it so well that they have set the world-wide standard

Answer 9

can't remember the name of it but in the med there are some schemes that you have to exit to the right of the channel to turn left and cross the channel perpendicularly. never heard of a "one way".

Answer 10

I have never heard of one certainly not around England or Western Europe
