So far I have discussed the concept of fundamental parameters in highway geometric design (for example, here) and the fundamental parameter “road type“. This post covers the fundamental parameter “vehicle type“. Vehicle type relates directly to design vehicles – the … Continue reading
I began a discussion about fundamental parameters in highway geometric design recently. The first parameter in my list is road type. A feature of “road types” is that they are associated with specific details of highway geometric parameters in all … Continue reading
Not exactly new …. In a previous post (here) I wrote: Non-motorised transport (NMT) is as much a part of road transport systems in countries such as the UK and Holland as it is in countries such as Uganda and … Continue reading
Other complications with standards Layout One problem with some standards is not the format – pdf or paper for example -but that you have to search backwards and forwards through many pages of the document before you find all the … Continue reading
The previous post in this series gave an example of a two-dimensional classification for roads, and asked: What would be the features suitable for use in a 2-dimensional code for the geometry of roads? The same post argued that when … Continue reading
This is the first of a short series of (short) posts on a new road classification.
Nutzrad.de is a one-man operated web catalog with details on work bikes, for example cargo bikes, child transport bikes, sales and advertising bikes, rickshaws and others. To date the website has details on 563 work bikes from 171 different manufacturers … Continue reading
In an earlier post (here) I argued that there are in effect only two types of road. For example I said that:
The theory of road classification puts motorways and other arterial roads at the first level; and human nature being what it is, the first level is automatically assumed to be the most important level. Yet this doesn’t make sense.
I used to think that pedestrians were – well, pedestrians. Once you had the typical dimensions and walking speed for an adult person, that was all you needed. However, when you start taking a closer look things (as always) become more complex.
