Placement of traffic sign

[airmintie]

Hi guys,
I'm new here and a new graduate. I just got a job in Edmonton, Alberta, Canada.

There are two signs in which I am to place, a "50 km/h ahead" sign and a "50 km/h" speed limit sign. Now the distance I need between the 2 is the distance required for a car to decelerate from 80 km/h to 50 km/h. Does anyone know if there's a standard I could look this up, or what to look up? I'm having trouble finding any information relating to this matter. Thanks a lot.

I just realized there's a traffic engineering section so I posted this thread there. Sorry for posting in the wrong section. Any opinions would still be appreciated though. Thanks.

In the USA, each state has a state department of transportation. Ie TxDOT, Caltrans, UDOT, etc. I have found they have a plethora of standards to follow regarding a question like that.

My guess is that Canada would have the same type of standards in place. I don't know if it would be federal, or by district. That is the first place I would try to take a look. Probably google 'Canada highway design standards', and I bet you'll find a ton.

The Transportation Association of Canada (TAC) publishes a Manual of Uniform Traffic Control Devices for use by Canadian jurisdictions. Although it serves a similar role to the FHWA MUTCD, it has been independently developed and has a number of key differences with its American counterpart, most notably the inclusion of bilingual (English/French) signage for jurisdictions such as New Brunswick with significant anglophone and francophone population, and a much heavier reliance on symbols rather than text legends.

The Ministry of Transportation of Ontario (MTO) also has historically used its own MUTCD which bore many similarities to the TAC MUTCD. However, as of approximately 2000 they have been developing the Ontario Traffic Manual (OTM), a series of smaller volumes each covering different aspects of traffic control (e.g., regulatory signs, warning signs, sign design principles, traffic signals, etc.).

Took me awhile to find the MUTCD, but I eventually found it. Thanks a lot for pointing in the right direction.

Don't put the signs behind a tree..... like they seem to do around here....

Put it behind a tree and create a speed trap!!

the standard here is 750-1500'on a conventional road (not a freeway or expressway)
