This is a question probably for the lawyer folks here and here it is:
If the police can establish that today I drive from Calgary at 7am to Edmonton and arrive at 9am. Can they prove that I spent my way to Edmonton from deduction (280KM/2hr=140KM/hr)? On what legal principle the police can or cannot charge me for spending based solely on the above deduction? Thanks.

They actually use this system somewhere (England maybe?)
They will have 2 cameras a certain distance apart. The first camera takes a pic of your plate with a time stamp. The second takes a pic of your plate as well, and uses the time stamps between the two to figure out how fast (average) you went to get there in that time.

These are average speed cameras and are a PITA on the M-motorways.
To the OP: technically yes - If they can PROVE when you left a point in Cgy and arrived at a point in Edm, they could ticket you. They'd have to have some great evidence supporting the times, but theoretically they can.
They something similar in Ontario, using planes to watch people's time from point a to point b on the 401. This is the same concept legally, but practically? Can't ever see it happening.
They're not going to do this kind of work with a distance of Calgary to Edmonton. They'll usually do it over a distance of a kilometer and simply use road cones and a stop watch from an aircraft.

i think they would stop you in airdrie - although in my expereince of driving hiway 2 - there are very few police cars on the hiway between calgary and red deer, and from RD to Edm there are lots of police cars

I always wondered if you get speeding tickets on automated tollroads based on entry and exit times
I never have on the 407 and I use it all the time.
It's a privatized highway though and they want people to use it, whether they are speeding or not. So it's not like the people who run the 407 want to discourage people from using it.
Maybe the police could request the records, but I don't see that going over too well. The whole purpose of ticketing speeders IMO should be for safety and not just a money grab. If you don't stop someone in the act, you aren't really doing anything to make the roads safer at that moment since for a lot of people, fines are nothing.

Isn't this part of initial calculus courses - that you can take a derivative of your distance and time profile and prove that at some point you must have had a speed of at least the average (140km/hr) at some point during your travel.
Outside of math/calculus proofs, it just makes logical sense as well.
Most likely enough to charge, would you ever see a conviction out of it? I doubt it. Furthermore, unless they actually physically ID'd you as the one driving, it could only be a registered owner ticket.
