Produces a cycle map aimed at a recumbent trike rider with a trike 1.01 metres wide. - Any barriers which have an available width of less than 1.01 metres, and are on a route that could be cycled are shown with a red B in a circle. The map is routable, but will not route you through a barrier you will not fit through (caveat, if the opening width has not been updated on OpenStreetMap (OSM), then the map displays the red B in a circle as a warning that you may have a problem there (Perhaps you could update OSM so that the next trike rider has a better map).
The aim is to produce a map which you can use in a garmin cycle computer with your trike, able to route you, and which you can search for features. But perhaps more importantly, you can view the map on something like QMapShack, Garmin Basecamp or just on your actual cycle computer, and see if there will be some kind of 'hiccup' which will cause you problems when you find it. Personally I've found problems on 'The Avenue Verte' where I found a bridge with hundreds of steps that defeated me, NCN1 in the UK with cycle barriers that blocked me, and a railway bridge in Scotland that I had to take a 10 mile diversion round the roads to avoid when riding my recumbent trike.
Using MKGMAP it is possible to create a map that only shows barriers which will affect a vehicle (in this case a recumbent trike) of a certain width. One of my trikes is just over 1 metre in width, so that's the width I've chosen whilst creating this map. For instance, any bollards which have a gap between them of 101cm or less are shown on this map, and their actual available width of 'gap' is shown. If the bollards don't have their width of opening (maxwidth:physical) marked on OpenStreetMap then bollards will appear on the map as 'Bollard Gap?' - it's easy to update OpenStreetMap so the actual gap is shown.
This map has been created using OpenStreetMap data, and a number of other programmes to manipulate the data.
As a recumbent trike rider, I would like to have maps on my navigation devices that assist me. I have NCN 1 fairly near me, and fond memories of riding it when I rode a 2 wheel bike and was a Sustrans Ranger, but parts of it are a 'show stopper' for me on my trike as they have narrow gaps between bollards which require me to get off and try to lift the trike over a chest high gate - not easy or fun for me if on my own - I'm thinking that some kind of warning on the map so I can chose whether to try to negotiate the barrier, or not go that way at all, would be helpful.
