I used to use this as a far-fetched example when talking about the benefits of retroactive landmark reports:
“Let’s say you catch one of your drivers buying crack at a crack house — don’t you want to know which others may have visited there in the past year or more?”
Well, in Detroit, they actually found a city employee’s vehicle at an actual crack house.
It’s detailed in this Automotive Fleet article.
So, now that there is a real life example of this, how would you use GPS Insight to easily determine the other vehicles which have visited that same crack house?
Here’s how:
First, find the exact location by looking at that vehicle/date/time and create a landmark with the convenient link from that point (we’ll pretend my house is a crack house).
First, run a 3D history map for that day (pretend yesterday):
I’ll pick the “crack stop” at my house (really me coming home from taking the kids to Buffalo Wild Wings, a different kind of crack) and blur the street names in case anyone wants to come see for themselves — then I click on “Landmark: Create from Point”:
Now I choose a Polygon landmark, change the color to green (why not?), and outline the areas a vehicle might PARK IN (not my house, which is a common mistake — you want landmarks to be where people park, not where the actual landmark is!).
I call it “Crack House.”
Now when I refresh my menu to pick up the new landmark under “Reports: Landmarks” I can run a 1 month at a time landmark report (note clicking the month name selects the entire month):
Other than my wife & I, no other vehicles show up in December, so I go to November and see that a few other vehicles have been tracked in that exact area. Note the “Passing through” option which is checked — this means the visit will show up even if the ignition is not turned off while there (e.g. a drive by drug buy — my guess is crackheads like to idle too).
There was too much activity for my vehicle (with 3-4 devices), my wife’s & the company Scion (3 devices), so I created an “all but robs” group and ran the report against that:
So Elliot and Ryan were in the crack house zone in November:
You get the idea. Obviously this is just a simulation — Elliot was dropping off a credit card we had forgotten at a restaurant the night before, and Ryan was dropping my wife off after her car needed service.
But what is important here is GPS Insight allows you to go BACK in time to check for landmark activity.
Several competitors do NOT (including two of the largest/oldest ones in our space). They will only allow you to report on landmark activity in landmarks which you created BEFORE the activity took place.
That means you would need to know all the crack house locations in advance! I hope our customers don’t have that information handy.
Although, I’ve often said you would have to be smoking crack to go with another solution…
