Route points: Some non-alerting, some alerting

[Mikey]

Having created a route by placing START and END points, I then proceed to place Route points along the Route. I have been doing this with the Insert tool.

Question: Why is it that some of the Route points show in the Dialogue box as Arrive/alerting, and others as Non-alerting? I did not specify each, but simply clicked each in along the Route.

I know I can change each Route point to Via or Shaping, but I am just wondering why/how BC makes up its mind as to how it initially lists them (arrive/alert or non-alert) in the Dialogue box (?).

Thank you, Mikey

Varies depending on whether you, intentionally or not, click on a spot that the map has as a specific point.

I placed the Route points on the magenta route in ‘wide open road’ nothing nearby that I could see, so I am curious as to why there are non-alerting and alertings (???).

Thank you sussamb,
I will have a closer look. I understand your post. It makes sense.
Cheers, Mikey

It's not a complete answer, but if you insert a point on a junction it doesn't alert.

That is interesting Colirv. I did not know that.
One of my forum learnings is to place route points on the desired outbound leg of an intersection, and generally not at the junction, so I take that approach. I hope I have that correct, I understand the reasoning behind it.
Thank you.

IMHO yes, you have this correct. I never place a point at a junction. There are several reasons for this.

I've often wondered about the alerting/nonalerting thing too. It seems random to me. I've heard the "click on a specific point" reasoning but that doesn't seem to apply. To me it really doesn't matter, it's a minor thing, notworth worrying about.

IMHO, it seem that if Basecamp can identify an address with the point clicked, then it will make it an alerting point, otherwise it won't. I, like @Mikey, also learned to avoid placing route points at junctions. In my early routing and XT days I had an issue with a route point at a junction which manifested itself in the XT seeming to be confused. I don't recall the details but have avoided route point at junctions ever since.
I now wonder if that route point was placed off the center of the junction so caused the problem. I recently surprisingly learned that when you shape a route using the XT, it will place the shaping point in the closest junction. Based on that, along with the fact that some folks here place their route points at junctions, I plan to stop avoiding doing so, at least for route points whose sole purpose is to keep me on a specific road. If there will be a turn, then I will place the route point away from the junction on the road in the direction of the intended route, knowing that these will need to be checked for alerting status.

My guidelines for route points in intersections:

• Shaping points placed in intersections are always fine if I will not be turning. Shaping points in turning intersections are OK if they will never be changed to via points. Shaping points placed in intersections with turns, and later changed to via points on the XT, have caused my XT to reboot when arriving at that point. So, I pick another intersection before/after the turn intersection for a shaping point if there is any chance it may become a via point later.

• A Via point in an intersection is usually a bad idea. Alerting of via points takes precedence over alerting of turns. The turn is never announced, so if I am not watching the screen, I may miss the turn. I have also seen imprecise via placement in the intersection turn a simple left turn into straight→uturn→left→uturn→straight.

This is all sounding very complicated. My simple rule is that shaping points go on junctions, default is not to announce, via points never go on junctions, default (IIRC) is to announce. "Turns" to me are simply products of a route once it has been formed, not part of its formation.
