Mapping turn-restrictions for navigation in 30 cities in US #187
Description
Aim:
To map turn-restrictions in 39 US cities using Mapillary as the source.
Task Workflow
- Here is the workflow to follow to add turn-restrictions to OpenStreetMap.
- Here is the spreadsheet where we will be tracking the progress.
Team : @mapbox/team-data
Features to map : Turn-restrictions by using mapillary as the main source and Bing/Mapbox Satellite imagery.
Process:
- Two team members can pick one city together and update the spreadsheet with their name.
- Before starting the mapping run the below overpass query by changing the city name in the query and update the spreadsheet with number of turn-restriction present before mapping.
- Overpass Query: http://overpass-turbo.eu/s/gqr
- Divide the city into half based on a road/landmark and work at different parts of the city.
JOSM Setup
Plugins:
Paint Styles
- Traffic Signs : JOSM Preferences -> Map Settings -> traffic signs

I came across few Mapillary images in Los Angeles where the turn-restriction was written on a turn-lane boards (white background and black signs).
In such situations make sure to add
no_u_turnturn restrictions.More information: Refer Department of Transportation (DoT), California document here.

@mapbox/team-data have been working on adding turn-restrictions in 30 US Cities to improve the navigation data.
Process we are following
Below is the overpass query to run for all the users who are working on turn-restriction. (Need to change the timestamp as required)
http://overpass-turbo.eu/s/gxe
The number of turn restrictions already present in the cities listed below can be found here. Below is the list of cities where we are adding turn-restrictions:

We have updates to the experimental OSM navigation map to help review and add turn restrictions from Mapillary quickly.

Features
ValidRestriction is correct and has been mappedRedundantThe restriction is correct but is not useful to add to the map. eg. No turn against a oneway.InvalidThe restriction was wrongly detected, is temporary or in the wrong location. Do not map.Please submit feedback and file issues at https://github.com/planemad/osm-navigation-map/issues

Reminder to @mapbox/team-data to take care of conditional restrictions like this:
The correct tagging is
restriction:conditional=no_left_turn @ (Mo-Fr 06:00-09:00,16:00-18:00). This is already documented in the workflow.Also be careful with conditional restrictions since JOSM will not recognize
restriction:conditionaland will not display the type in the relation list. Here duplicate restrictions were added to the same roads.poornibadrinath commentedon Jun 2, 2016
While marking turn restrictions near one ways as redundant, it would be great to check instances like this with u turns.
While left and right turn restrictions near one ways are redundant, u turns on one ways can be valid.

@mapbox/team-data I want to attract your attention to this case of turn restriction https://www.openstreetmap.org/relation/2573759.
Here is
no_left_turnrestriction with 3viamembers!This restriction makes sense because of the markings before the crossroads. Here is solid marking so drivers not allowed to change their lanes from the node where
motorway_linkjoin to theprimaryroad down to the intersection. Drivers traveling from the motorway may move only by the most right lane to right. On the other hand, drivers moving alongprimarynot allowed to make right turn, that described by this turn restriction - https://www.openstreetmap.org/relation/2573760Please be careful when you are editing

The Mapillary layer in the navigation map is showing a series of possible turn restriction images.
A series of mapillary images with possible turn restrictions in Georgia Avenue
But when I am opening the at same area in JOSM, the mapillary plugin is not displaying the series of images that are displayed in a line around "Georgia Avenue".
No mapillary images displayed in JOSM
The plugin has been updated and I have tried deleting and loading the mapillary layer again multiple times. The problem still persists.
Is this because the mapillary layer has not been updated?

@planemad
While working on turn restrictions, I found some stuff that I think could be improved.

Week [ 30th May 2016 - 3rd June 2016]
The team has completed adding 425 turn restrictions in a total of 14 cities since 25th May 2016. This week the team completed 9 cities and added 216 turn restrictions in the following cities:
Please refer to the above table to get more details about the cities completed and the cities that we are currently working on.

@samely looks like there was some confusion in the style. have updated it:

Great work team 👏
A team of 14 members worked on 32 US cities adding 1178 turn restrictions in 13 days. The time spent on each of the cities varies based on the Mapillary coverage and number of turn restrictions detected. The city-wise stats can be found here.💥

This is the trial run on the proposed work-flow to be followed to validate the turn restrictions added by the team in the 30 US cities.

@mapbox/team-data team has completed the validation of close to 900 turn restrictions mapped in the 30 US cities using the above work-flow. The team will next jump into validating 300 odd
conditional turn-restrictionsin these cities.jinalfoflia commentedon Jul 21, 2016
@mapbox/team-data completed validating the conditional turn restrictions in the 30 US cities.💥 No further actions here. Closing it.
