London Congestion Charging

Posted by Amaroussi on 28 February 2013 in English (English)

In the 8 years of OpenStreetMap, it is extraordinary that London's Congestion Charging zone has not been properly mapped. Some road navigation systems are now using OpenStreetMap - the absence of the Congestion Charging zone on OSM means that some drivers are accidentally driving into the zone without being aware of the £10-a-day cost.

To bridge the gap, I am gradually adding "toll=yes" to affected roads as an interim measure, but in the long term we will need a dedicated standard tag to indicate the Congestion Charge zone because the Congestion Charge does not apply to pedestrians, cyclists, taxis, TfL buses and motorcyclists. I feel that a dedicated tag is necessary because I note that there are similar schemes in the world, including Milan, Singapore, Stockholm and Durham.

Contributors are invited to discuss the future of mapping the Congestion Charge on OpenStreetMap. I think that OpenStreetMap is no longer a map just for cyclists and pedestrians, but for just about everyone.

The resulting map.

The subways will be filled up from the middle of February 2013, but who cares?!

When postcodes go wrong...

Posted by Amaroussi on 22 January 2013 in English (English)

Caledonian Road Area

Surely this area can't be part of the N17 postcode area: it's N7 instead! Additionally, searching for N1 doesn't return a postcode centroid for N1.

What is causing all the problems?

Hardly the end of the world...

London lighting data

We are 100% certain that today is NOT the end of the world: certainly not when 99% of all trunk roads within the M25 now have lighting data. To make it even better, the Southall and Mildmay areas have a lot more detail than when I first joined OpenStreetMap in late-October.

Here are a summary of improvements:

London

99% of the trunk roads and motorways within the M25 London have street light data. The next phase of this project is to extend such data to 99% of primary, secondary and tertiary roads. These roads are all-purpose, meaning that cyclists and pedestrians will use it.

Southall

Not celebrating Christmas does not imply that we can't improve Southall during that time: so far, we have added street light data, previously uncovered alleyways and tracks, footpaths and cycleways (particularly with car parks and recreational parks). We have also marked out tertiary roads, places of interest, businesses and key places of worship for the Sikh and Hindu community.

Mildmay

So far, we have added street light data, traffic calming information. We also marked out previously uncovered footpaths, tertiary roads, and added many businesses and points of interest. We also added all the bus routes around the area.

Light up my way!

Posted by Amaroussi on 20 November 2012 in English (English)

Streetlights affect how you plan a safe road journey at night - another thing Google Maps cannot do. Recently, Transport for London has removed the lights from the Hammersmith Flyover (A4) and parts of the Westway (A40), and this means that drivers need to take extra care at night.

Mapping the streetlights on London’s roads is one of OpenStreetMap’s aims, and recently I have added relevant data for many London roads, including the A4 and the aforementioned sections that TfL have removed the streetlights.

Did you know that you can drive from London to Newbury using only roads with streetlights? You obviously cannot use the M4 (unlit between Junctions 8/9-10 and 12-13), but the A4 instead (except for the detour to avoid the Hammersmith flyover).

Addendum: I should also point out that you can also drive to Southend using only roads with streetlights, by following the A13.

Addendum II: I should also also point out that most of my data came from driving trips over the last two years, as well as recent public transport trips within the M25. I respect the privacy of the drivers given the current problems with cyber-bullying on the internet, but thanks.

Improving Canonbury and Mildmay Park

Posted by Amaroussi on 2 November 2012 in English (English)

Hello cartographers, I would like to introduce myself as a mapper for the Canonbury and Mildmay Park area in North London. OpenStreetMap Users who visit this area often will notice that I have either added or improved many new features in the area because I live around there.

Key improvements include more bus routes, gates and pedestrian paths: for example, it is possible to walk from Mildmay Avenue to Mildmay Park without using Balls Pond Road.

Remember, making OpenStreetMap better than Google maps in terms of quality is dependent on contributions from local people like you. Therefore, if you know a lot about your local area, please join in: Phyllis Pearsall did not use the GPS when she created the original A-Z.
