Am I missing something - how do you see the names? When I click on one of the vehicles I see "Vehicle Location (PN61DYG)" and the name field is blank.

Zoom in until the names appear on the map, you don't have to select each vehicle - sadly they don't all have names.

Huh. Doing a search by name allows me to find some. But only the ones I've searched for by name _have_ a name. The rest have no name when I click on them. That's...weird.

I live in a warm place so I am out of touch, but isn't that like a lot of gritters for how small Scotland is?

The trunk road network is 2179 miles (3506km) long and there's ~120 gritters deployed. Doesn't seem like an unreasonable amount to me.

2179/120 means each one has to cover about 18 miles. Assuming they average 36 mph, assuming each trunk road is 2 lanes in both directions (assuming one pass per lane and not including time to clean up the shoulder/median), and assuming they spend 50% of their time gritting/plowing new roads rather than filling up/changing drivers/driving on plowed roads to get to or from their target road, that's one pass every four hours. Seems quite reasonable (if a bit undersized) to me as a Michigander.

We're having unseasonably warm weather here - it's 45 and sunny instead of a typical 25 and overcast - so all the snow has melted in Southwest Michigan and our state plow tracking map is basically blank today:

We have about 800 snowplows to cover 12,000 miles of state/trunk roads (15 miles per vehicle). It requires about 2,000 operators to keep those 800 plow trucks running 24x7 when it's really snowing.

In Michigan we have webcams on the front of our snow plows, in addition to their GPS location. This is useful for seeing road conditions throughout the state in places that don't have traffic cameras.

Just click the little icon that looks like a snowplow on this site. No plows out today, however...

Took reading the comments to figure out what a gritter is. (Here in the States.)

Here we'd call them sanders or salters. It was an even bet for me between that and maintenance of oiled gravel roads. It's basically a lower cost version of asphalt. Every few years, they sprinkle some gravel, and spray with heavy oil. The odor is horrible, and vehicles get dirty.

Typically we refer to them as 'plows' or 'snowplows' in the US midwest regardless of what they're actually doing—they often (but not always) have a large plow on the front, and a salt/sand spreader on the back, or in some cases a sprayer that shoots out fine mist that gets your car all grimy and nasty for the next day or two.

I'm amazed Scotland have a real time map with also how long ago a road was gritted - much respect to them. And the Gritter names are hilarious - but sadly don't (in my mind) beat Doncaster's "Gritsy Bitsy Teeny Weeny Yellow Anti-Slip Machiney"

I'm pleased to see they have a 'Mr Plow' in there, for the Simpsons reference!

Having never heard the terms "trunk road" or "gritter" it took me a little time to figure out what this was. Correct me if I'm wrong but "trunk road" appears to mean something like main road and "gritter" seems to mean plow and/or sanding truck.

"Main road" is actually considerably more general than trunk road in the Great Britain. The roads in GB are ordered hierarchically starting with motorways (although these have restrictions, ie. motorvehicles only), through trunk roads, primary, secondary, all the way down to byway.

It is important for navigation in GB. When you want to go somewhere you are supposed to use trunk roads to navigate to the first town/city on the trunk network beyond where you are going. The signs are coloured to indicate you are on the trunk network. Then as you approach your actual destination you will begin to see it signposted on the local non-trunk roads, at which point you leave the trunk roads.

This has been mostly forgotten in this age of GPS navigation, though, and many signs are in a poor state of repair or badly occluded by trees or shrubbery.

I'm from the UK and was unaware of this method (trunk road to town/city after destination).

Is there somewhere I can read about this in more detail?

Thanks!
