I am new to this forum, so hello to everyone.
I have started working on a design for a cycle network for Edinburgh. At the moment I am just playing around with it, but I would welcome the opportunity to work cooperatively on this.
I was inspired to start work on this following a recent blog by Sara Dorman (here). If you can spare the time, please also read the comments.
As part of the planning process, route selection is very important. I tend to design from patterns to details, but this is useful only up to a point. It also helps to know what's missing.
I have started laying down routes as can be seen here. Going forward, I wonder if it would be possible to recreate this map in a separate Google account, and then to share the password amongst forum members. People can then change or add stuff as they fancy.
There are two ways to approach the development of a cycle network. One way proceeds by analysing situations (that is, the type of roadway, level of traffic, frequency of accidents, proximity of facilities, etc), and building from the bottom-up.
As far as it goes, this work is very necessary. However, according to Cycling: the way ahead, it is possible to “go much further than this strictly pragmatic and ad hoc approach”, and if I might be allowed a metaphor here, basically what you need to do is look through the other end of the telescope. That is, approach the development of the cycling environment from the top-down, by analysing journeys (origin / destination). This would then provide you with a strategic overview, enabling you to see ‘the bigger picture’, and from here you can then plan the network that would provide for these journeys. This ‘global’ approach is known as the Voluntarist policy.
Once the network has been planned and studied, the next step would be to "introduce" it so that it works. Such a network might very well be suitable only for about 10% of the population, but it is far easier to set about providing for the majority of potential cyclists working from within the framework provided by a functioning cycle network, and given a cycling modal share of about 8%, say.
Either way - top-down or bottom-up - you need to be thinking something like twenty years (the Dutch programme these things to work in twenty-year cycles).
I hope this sounds agreeable.
