HavanaDay wrote:@CBenson. This is what I know and have seen. If you mark the roads in a bigger neighborhood with just private roads at the entrances it will not route you out at the most efficient manner.
I have also not come across this issue - at least not where private roads at the entrances (or split roads with one direction private) worked. I was under the impression that the private road penalty was designed to prevent routing through a neighborhood where all the roads are private. If this isn't working we really need to revisit the basic operation of private roads, don't we?HavanaDay wrote:Now if all the roads are private in the neighborhood there seems to be some issues with still allowing routing to go through there even if it isn't your destination.
I'm not suggestion to use parking lot roads for private installations (or areas prohibited to through traffic by signs if we are treating them differently). I'm just saying that the through routing penalties are similar for areas of parking lot roads and areas of private road segments. So if something is already considered a parking lot and mapped with parking lot roads, then there is no reason to do anything else to prevent through routing.HavanaDay wrote:Regarding using parking lot roads (not specific to the case above) but isn't that hacking the map?
I haven't formed an opinion on that matter yet. Still waiting for a tile update so we can see if there are any differences between putting the private road segments on the entrances or the exits of a private installation with split roads at the gates.HavanaDay wrote:Has your opinion changed after posting in this thread, Or do you consider it two seperate matters?

If we go by how sings are displayed, we know that the direction of the sign is were the intended instruction is meant for. Since there is no other "No thru traffic" sings facing the other directions, it's safe to assume that it's meant for the off-ramp traffic so they don't go packing through the narrow opening.

Fredo-p wrote:As for the extended curb, I mentioned it before. IMO, I believe the curb is extended due to the fact that the road allows for curb/street parking. What was developed was a "bubble" curb to protect the parked cars from traffic coming in. This also indicates how restrictive the community is for traffic if they went as far as having the curb bulge out that far.
Fredo-p wrote:In regards to the curb and how narrow the opening is to this street, I don't think it plays any part in figuring out what to do, as it's just a effect from the design. I can say that is one hell of a right turn if your traveling south.

Case in point, in a neighborhood near me, a small island was added in the middle of a road to reduce through traffic between the neighborhoods. In the words of the city planner (yes I directly spoke to him at one city counsel meeting), "the constricted width of the street will reduce the probability that someone would pick that route out of the neighborhood."

So if I understand you correctly, you are saying that when routing out of an area that complies with the alternate treatment for larger installations you sometimes get inefficient routes. If so, I haven't come across the issue. But if the split road method works and the single segment method doesn't, maybe we should eliminate the alternative from the wiki.

I disagree, if the sign were on the final few feet of the ramp, you would have people arguing that the turns onto Sawtelle are included and the entire exit is only for local traffic.
