[Script] WME LiveMap closures

[pvo11]

I made a simple script that reads the info (line) about the closure from the Live map and shows it in WME as red and white line.

WME LiveMap closures
https://greasyfork.org/scripts/5144-wme-road-closures
Current version: 1.16

The script adds new layer LiveMap closures and has no other user interface.

Here is an example of some closure in the Live map:

and the corresponding picture from WME:

Previous name of the script was WME Road Closures.

I’ve tried to make a dashed line similar to the Live map but it didn’t look so nice. The same was with the black border around the line. This simple red line was the best result of my testing.

I think the icons are not necessary in WME they could hide some other segments. It would be more annoying than helping. The same is with the information about the closure details. The Editor usually does not need this information for editing; he needs information that there is a closure, which means: “Don’t touch the segments”. If he needs in an exceptional case some additional information, he can easily switch to the Live map.

My intention was to make a simple script without any bells and whistles, which is fast and can be switched on all the time.

Right now, you are hardcoded for the ROW routing server. There is a sample function located in WME Live Map Alerts Overlay that can get the server name from Waze.location.code (or W.location.code) since the routing servers differ.

I also like wlodek76’s suggestion in trying to build the dashed line similar to LiveMap. While it’s not the same red line as a segment without any information, we already have “red roads” for that purpose.

I’ve posted new version 0.2 which should use the right routing server but I didn’t find any road closure in the USA to test it there. Please could you test it or send me a permalink of a road closure?

I will try to make the line nicer but it needs more testing.

I’ve found some closures in the USA already and the script works there now.

Btw. Maybe there is a chance to simulate this dashed line using OpenLayers.
Try to draw two lines for the same segment and create a different dash pattern:
1 line - strokeDashstyle ‘solid’, strokeColor ‘#FF0000’
2 line - strokeDashstyle ‘dash’, strokeColor ‘#FFFFFF’

This doesn’t work. When I draw two lines with the same geometry, only the second one is shown. It doesn’t mater if the second one is solid or dashed.

try playing with the opacity with line 2. You may end up with pink dashes instead of white, but it would be distinctive!

Even in this case only the second line is shown.

[pvo11]

With two layers I was able to draw dotted line in 2 colors but it looks horrible.

[taco909]

It doesn’t look the best, but IMHO it’s better than having it look like an unconfirmed (red) road.
It would actually be better with the black borders.

Remember, this isn’t being presented to the drivers on the app. This is a tool for editors. We can handle a reduction in aesthetics if it helps to clarify what we are looking at without having to select the segment.

[steveningelbrecht]

Thanks for this great script! very handy

[pvo11]

New version 0.3 is available.
I’ve found an error in generating the overlapping lines and the dotted line works now with one layer only.
Additionally I’ve improved the design of the line (check the updated picture in the first post).

@wlodek76

Is it possible to get these both scripts to work together better :?:
I mean that WME Road Closures hides icon of WME Live Map Alerts Overlay :-/
Maybe it is possible to manage their Z-Index and get icons on the top.

I’ve prepared a new version which changes index of “Road Closures” layer (Z-Index change didn’t help) to be lower than “LiveMap Alerts Overlay” layer. It works fine the Road Closure line is shown under the alert icons but the “LiveMap Alerts Overlay” doesn’t show the alert details in this case therefore I dint not post the new version and I will contact davielde directly to find common solution.

@wlodek76

Btw. Did you think about linking all the segments into a one long line. The dashed line will have a continuity in drawing then. Ex. by checking start and end of each segment or their angles

Yes, I thought about it but it is not so important and it has no priority I will do it probably later together with changing width of the line based on the zoom.

[pvo11]

@wlodek76

Try this simple code, it seems to be a solution and it works fine.

I’ve posted new version with simplified modification of your code. It works fine. Thank you for your sample.

[pvo11]

@wlodek76

Unfortunatelly your method in v0.4 doesn’t work at least for me :?

Could you send me a permalink to this or does it not work everywhere?

@wlodek76

I think you must to sort both Z-Index and apply them to both layers, because layers could be loaded in different order.

I think it is not necessary to set same values when they are in correct order therefore I didn’t use sorting.

@wlodek76

Btw. IMO perhaps lines are too wide, maybe strokeWidth 12,10,10 instead of 14,12,12 should be enough. However it could be a personal thing, I prefer thinner, narrower lines here

I think the width should depend on zoom but it should completely cover the road.

@wlodek76

Fix B a small improvement for situation where we do not have WME LiveMap Alerts Overlay installed

I’ve tested the version 0.4 in FF and Chome, both with and without WME LiveMap Alerts Overlay and everything worked correct. It is strange. I will try to test it with different script order in the Mokeys.

[pvo11]

@pvo11

I will try to test it with different script order in the Mokeys.

I’ve changed the execution order of the scripts but it works fine too.

There are two differences between your and my code.

1. I don’t search for my own layer because I have it in the variable closuresLayer
2. I don’t set setZIndex if there is no change
   Włodzimierz could you apply this two changes to your version to see if some of them is the reason of the problem in your browser?

[davielde]

An updated for LiveMap Alerts Overlay has been released with the requested changes to layer and offset as well.

[pvo11]

It is strange with your new version is the road closure line in the front of alerts icons. With the old version was the line behind the icons.

This means now I have the behavior as Włodzimierz has and I can test it.
This cold be the differnce. Włodzimierz probably modified both scripts and I did may test with unmodified WME LiveMap Alerts Overlay.

[pvo11]

@wlodek76

I will try to investigate the problem and I will test it more acuratelly. Maybe it is something with the layer ordering :roll:. I have more then 10 different scripts for wme installed

I’ve tested my script with your code with the new version of WME LiveMap Alerts Overlay an the behavior is same as with my code. The line is in the front of the icons on my computer in both browsers.

[pvo11]

It works on my computer now; the new version of WME LiveMap Alerts Overlay has different uniqueName = “__livemap_alerts”. Therefore my script didn’t find the layer.
I will wait with the new release for Włodzimierz’s tests.
